Bigshopper Frequently Asked Questions (FAQ)

 

What does Google CSS mean?

The Google CSS program (CSS stands for Comparison Shopping Services) started in 2018. Google was fined a record fine of 2.42 billion euros by the European Union in 2017. The reason: Google places the results of its own service Google Shopping at the top of the search results, to the detriment of competitors (other price comparison companies, such as Bigshopper). In order to avoid new fines, Google has had to adapt to Google Shopping in order to allow more competition. This adaptation marked the start of the Google CSS program. This means that only price comparison companies (such as Bigshopper) that meet Google's requirements can become a partner of the Google CSS program. The European Commission requires Google Shopping to be profitable in an independent way. This means that affiliated Google CSS Partners have an advantage of 20% margin in the auction of Google Shopping.

Google also explains this on https://support.google.com/merchants/answer/7558973?hl=en (Google explains in that article: "The European Commission requires Google Shopping to be profitable in an independent manner. Google Shopping currently does this by withholding a fixed margin percentage on each bid that sellers make before it is submitted to the auction. This margin is included in the CPC paid by the seller and is only charged when a user clicks on one of the seller's advertisements'). In short: through Google CSS itself 20% of your bid within your Google Shopping campaigns goes directly to Google, only 80% of your bid goes into the auction. If you join Bigshopper CSS, your full bid will go into the auction. You would have to bid 25% via Google CSS to achieve the same (after all: if you bid 1 euro, you enter the auction via Google 80ct, you have to bid 25% to get back to 1 euro CPC). Also on https://shoppingsolutions.withgoogle.com/faq Google explains the margin with the question "What is Google Shopping's pricing model?".

 

Why did Google launch its CSS (Comparison Shopping Service)?

Google was fined a record fine of 2.42 billion euros in 2017 from the European Union. The reason: Google places the results of its own Google Shopping service at the top of the search results, to the detriment of competitors (other price comparators, such as Bigshopper). In order to avoid new fines, Google has had to adapt to Google Shopping in order to allow more competition. This adaptation marked the start of the Google CSS program. Due to the requirements of the European Union, Google has to offer a model where other price comparison companies can charge margin. Because of this requirement, there is now an advantage in Google Shopping if you are a price comparator. By working together with a CSS Partner such as Bigshopper, you can make use of those advantages. The requirements for the CSS program of Google have been tightened several times, the last time in February 2020.
 

Why Bigshopper CSS?

Several CSS Partners are active in Europe. Why choose Bigshopper CSS? The main reasons:

  • Price: you pay a fixed amount per month. Do you spend more than 250 euros per month on Google Shopping? Then it pays to switch to Bigshopper CSS.
  • .
  • Bigshopper is one of the few Premium CSS Partners in Europe.
  • 20% margin advantage within Google Shopping
  • Bigshopper is active in all European countries to which the CSS program applies
  • .

  • Support: both support from Bigshopper and Google (because Bigshopper is a Premium CSS Partner)
  • .
  • No hidden costs and no CPC (cost per click) model
  • Bigshopper has signed a management waiver with Google. This means that Google contacts will keep access to the Google Ads accounts to which the Merchant Center is linked that are linked to the Bigshopper CSS.
  • .
  • Bigshopper complies with Google's policy requirement that a comparator has been set up for each country/language and that a CSS MCA (Multi Client Account) has been requested and approved for each country/language. We have also set up our own system (approved by Google) with which users can be redirected to the correct domain (e.g. as a Merchant Center that links multiple country targets to one country)
  • .
  • Continuity and further development: thanks to the monthly fees, Bigshopper will be further developed. Bigshopper employs several programmers and support staff. Bigshopper is a high quality platform. This is reflected in the fact that, for example, all brands and categories on our site have texts explaining the products to consumers.
  • Bigshopper complies with the obligation (this can be found on the CSS partner page of Google as well as confirmed by Google by mail) that all products in the Google Shopping feed can also be found on the comparison Bigshopper
  • .
  • Traffic continues to increase on Bigshopper, no extra charges apply for all clicks out!
  • Bigshopper.nl does not work with affiliate feeds, on the Bigshopper.nl comparator there are only connected customers with a feed.
  • .
  • Bigshopper will not use/abuse the link to your Merchant Center, for example by linking its own Google Ads account to your Merchant Center and purchasing residual traffic (which will be resold at CPC rates or provided with affiliate links).
  • Bigshopper has already successfully connected many customers, this is good for the comparison function and continuity.
  • Bigshopper can link your existing Merchant Center account to the Bigshopper CSS, which has the advantage that Bigshopper does not have access to your Merchant Center and you keep your history.
  • Bigshopper does not need access to your Google Ads account.
  • Bigshopper has arranged an opt-in, allowing your ads to remain visible on the Google Shopping tab, at Google Shopping search partners, but also within other parts of Google Ads (e.g. remarketing).
  • At the transition, your ads will remain visible on the Google Shopping tab, at Google Shopping search partners, but also within other parts of Google Ads (e.g. remarketing).
  • Quick switch: it is now possible to switch from your current CSS (e.g. Google CSS) to Bigshopper.
  • within 24 hours.
  • Advertise traffic keeps on buying and going to your website without intervention.
  • Quick and accurate search function within Bigshopper (if a consumer clicks on "From Bigshopper" within Google, the Bigshopper site loads quickly with relevant results in the right language and for the right country).
  • The offer on Bigshopper is updated several times a day. Our algorithm is continuously being improved so that as many similar products as possible are bundled.
  • If a feed cannot be retrieved, we will be notified and will take action so that visibility remains optimal.
  • A notice period of only one calendar month.
  • Bigshopper deploys Comparison Listing Ads with the highest possible visibility (no exclusions). These are ads in Google that can only be used by CSS Partners. Although this involves costs for Bigshopper, we do not charge any additional costs. This visibility is included in your monthly fee. Comparison Listing Ads can only be used by CSS Partners.

Kortom: enough reasons to join Bigshopper CSS directly.
 

How does Bigshopper CSS work?

If your Google Merchant Center is linked to Bigshopper and you are fully transferred, you will immediately benefit from the 20% margin advantage in the auction. Bigshopper has no insight into your Merchant Center with an account association switch (90% of the switches). Bigshopper also never needs access to your Google Ads account. Another advantage of Bigshopper CSS is that we will never advertise your products. You continue to advertise yourself (and fully manage your campaigns yourself). The only thing that changes is that you will see in your account that you are part of Bigshopper CSS. So your ads will continue to go directly to your website (without traffic going to Bigshopper first). So, you won't notice anything of the transition, only that underneath the advertisements there is "From Bigshopper", a link that does refer to Bigshopper (but for which both Google and Bigshopper don't charge extra). Only if we need to create new accounts for you (which are directly under Bigshopper CSS and are not switched from you), we will have access to those newly created Google Merchant Centers (still, we won't have access to your Google Ads account/data).
 

What are the costs of Bigshopper CSS?

You can join Bigshopper with and without CSS benefits. If you take advantage of the CSS benefits, we will switch your Google Merchant Center, so you can immediately take advantage of the 20% margin advantage. If you want to be visible on Bigshopper without CSS (i.e. without us linking your Google Merchant Center to Bigshopper), that is also possible. For the prices of Bigshopper, please contact us via the contact page. It is important to know that Bigshopper does not use a CPC (cost per click) model in any case. You will pay a fixed amount per month which will give you the full benefit. If you use Bigshopper CSS, you also do not pay any costs to Google (nor to Bigshopper) if the "From Bigshopper" link is clicked under the advertisement.
 

What are the advantages of Bigshopper CSS?

The first advantage you have is the financial advantage of 20% margin in the auction of Google Shopping. This means that your full bid in Google Ads within your Google Shopping campaigns will be included in the auction. If you bid 20 cents, then immediately 20 cents will go into the auction. If you are currently advertising via Google CSS, 80% will go into the auction (in the example it is 16 cents). If you are now connected to Google CSS, you would have to bid 25% more to enter the auction with the same bid as a competitor that is connected to a CSS Partner (such as Bigshopper).

Previously (before 2019), in addition to the margin, there was also a kickback (a percentage that was refunded to your account as advertising credit). The kickback will expire on January 1, 2019. The 20% margin advantage is still active. We expect this to remain as well, given the fine from the European Union that Google has received (whereby Google must at all times offer a model that is fairly competitive compared to price comparison companies such as Bigshopper). Another advantage is that you always pay a fixed amount per month. For traffic coming from Bigshopper, you don't pay any extra costs (so there are no CPC fees). You may place your entire offer on Bigshopper, even if you only advertise part of your products in Google Shopping. This allows you to increase your visibility. Bigshopper has multiple partners (see our partner page) who can help you connect to Bigshopper CSS. Of course, you can also contact us directly if you have any questions. Bigshopper is active in more than 20 countries.

If you advertise in more than one country, you only need one partner (Bigshopper), with whom you can take advantage of the CSS benefits in all European countries. Bigshopper will also make sure that you will be informed as soon as possible in case of problems. If something goes wrong with your product feed, our system will notify you. This will first be checked by the Bigshopper team and if your feed no longer works, we will contact you. For optimal visibility in our comparator, we advise you to provide as much data as possible (preferably at least brand, EAN, title, price, URL, image URL). Inclusion on Bigshopper offers many other possibilities (for example, you may submit a promotional text for your retailer page on Bigshopper).
 

Does Bigshopper CSS advertise on my behalf after the switch?

It may seem that connected webshops advertise through Bigshopper but that is not correct. You will continue to fully manage your Google Merchant Center and your Google Ads account. So, the click costs of Google Ads will also go through your own account. So nothing will change, only that your account will be linked to Bigshopper CSS and that instead of "From Google" it will appear under your ads after the "From Bigshopper" switch. Clicking that link will cost nothing (Google will not charge for this either). However, by switching, you will benefit directly from a 20% margin advantage in Google Shopping.
 

20% margin, how does that work?

The European Union has imposed on Google that there must be a fair model, where other comparators can use Google Shopping, but must be able to achieve an acceptable margin. This decision follows a hefty fine imposed on Google by the European Commission. A price comparator that joins the Google CSS Partner Program therefore has an advantage of 20% margin in the auction. See also Google's own explanation on this subject at: https://support.google.com/merchants/answer/7558973?hl=nl Google indicates: "The European Commission requires Google Shopping to be independently profitable. Google Shopping currently does this by withholding a fixed margin percentage on each bid that sellers make before it is submitted to the auction. This margin is included in the CPC paid by the seller and is only charged when a user clicks on one of the seller's advertisements."

If you use Google CSS, Google will withhold the margin on your bid that goes into the auction. If you bid 1 euro CPC, then only 80ct will enter the auction. If you use Bigshopper CSS, we do not keep any margin, so 100% will go into the auction. You will then immediately benefit from a 25% higher bid in the auction (after all: you would have to bid 25% more to get from 80ct to 1 euro). The margin is something that Google CSS directly deducts from your bids, you will not see this in your account. However, you will notice a difference after the switch: your bid will be fully included in the auction (so you will bid more). Also on https://shoppingsolutions.withgoogle.com/faq Google explains on the question "What is Google Shopping's pricing model?" the margin that is withheld.
 

How do I transfer my existing Google Merchant Center to Bigshopper CSS?

Connecting to Bigshopper CSS is very easy. We will switch your Merchant Center account from Google to Bigshopper. This means that everything stays the same, only under the Google Shopping ads it doesn't say "From Google" anymore, but "From Bigshopper". Switches can be done every day, within 24 hours your account will be transferred to Bigshopper. Switching is very simple: you send us a so called "consent mail", in which you agree to the switch from Google to Bigshopper. You will then keep your own account and Bigshopper will not have access to your Merchant Center. Under no circumstances will Bigshopper have access to your Google Ads account.

There are important exceptions. This concerns TROAS, if you are using campaigns with the TROAS bidding strategy, then with every switch (both to and from a CSS) the learning period will start anew. This can temporarily have a negative effect on your campaigns. In that case we advise you to switch in a quiet period for you.
 

How do I connect my webshop to Bigshopper if I target multiple countries with one domain?

If you now have one Google Merchant Center with multiple product feeds focused on multiple countries (e.g. because you have a .com domain, where you target the Netherlands, Germany and France), we can easily switch your Merchant Center without having to split it by country. Bigshopper has developed a unique detection system that ensures that the user gets to the right landing page within Bigshopper (in the right country) when clicking on "From Bigshopper" under the advertisement.
 

How should the feed for Bigshopper be built?

To get your products visible on Bigshopper we need a product feed. This is an XML, CSV or TXT file that contains all the data of all your products. It is also possible to deliver a Google Docs document containing your products. It is important that the Google Docs document is publicly accessible (and not password protected). If you are using Google Shopping, you have probably uploaded a feed in the Google Merchant Center. It is possible to use this feed for Bigshopper. Of course, you can also create a new feed and tag the destination URLs (so that you can measure traffic from Bigshopper in Google Analytics, for example). In principle, Bigshopper can import almost any feed structure, preferably a feed that meets the Google Shopping feed specifications (see https://support.google.com/merchants/answer/7052112?hl=en). Don't have a feed? No problem! We can also make a direct link to your Merchant Center through our API connection. In that case you do not need a feed and we retrieve products directly from your Merchant Center.

Bigshopper has an extensive algorithm to bundle similar products, in order to do this in the best possible way, we advise to include EAN in the feed as a variable (within the Google Shopping feed this variable is called GTIN). It is also important that "brand" is included as a variable. A number of variables are mandatory, such as title, price, image URL and destination URL.
 

What notice period does Bigshopper use?

Bigshopper currently applies a short notice period of one full calendar month for new customers. This means that if, for example, you give notice on 20 January, the contract runs until the end of February.
 

My Google Merchant Center has been rejected, what should I do?

By switching from Google CSS (or another CSS) to Bigshopper CSS, nothing changes in Google's policy. This can mean that if you want to advertise with products that do not meet Google's requirements, these products will be rejected. In some cases it may even happen that your entire account is rejected.

Dismiss your account or if specific products are rejected, you can contact the Google Ads helpdesk if you have any questions about this. They can be reached on workdays until 5pm on 0800-0202736. Please keep your AdWords account ID and the Merchant Center account ID at hand.
 

Is it possible to claim my domain name in multiple Google Merchant Centers accounts?

Yes, you can. If you use Google CSS, you can verify multiple accounts with your domain name, but you can only claim one account on your domain name. This means that with Google CSS you can only actively use one Merchant Center to serve ads. With any other CSS, including Bigshopper CSS, it works differently. Each domain name can be verified and claimed at all times by a Google CSS Partner. In fact: it is possible to claim multiple Google Merchant Center accounts as a CSS Partner for one domain.

Please note: if you use affiliate marketing, it is also possible for affiliates in your program to verify and claim your domain name. If you don't want to, please indicate this in the terms and conditions of your affiliate program. Bigshopper does not advertise in any country or in any situation with affiliate feeds in the Merchant Center. Other CSS Partners do, please pay attention here. If you work with Google CSS, you can see which CSS Partner has claimed your domain and possibly advertises with your products (whether or not as an affiliate). If you want to check this, you can login to your Merchant Center. Then choose "Shopping ads" in the menu on the left and then select Configuration. You will now see a dashboard with all the CSS's that have claimed your domain name and possibly advertise with your products. If you use a CSS, for example Bigshopper CSS, you will no longer see this dashboard in your Google Merchant Center. You can then create a new Google Merchant Center for free (through Google CSS), where you verify and claim your domain name. If you do this, you will not lose your claim of your Merchant Center that falls under Bigshopper CSS (although you can get a warning). After claiming in the Google CSS Merchant Center (which doesn't have to be active) you can see the dashboard with all the CSS Partners that might advertise your products.
 

In which countries can I use Bigshopper CSS?

At the moment the Google CSS program is only active within Europe, given the fine that Google has received from the European Union. There are now more than 20 countries in which you can get the margin advantage through a CSS partner like Bigshopper. These countries are the Netherlands, Germany, Belgium, France, United Kingdom, Ireland, Spain, Portugal, Italy, Greece, Switzerland, Austria, Hungary, Poland, Czech Republic, Romania, Slovakia, Denmark, Finland, Norway and Sweden.
 

Where are the Shopping ads displayed via Bigshopper CSS?

The Google CSS program only applies to the advertisements that are displayed on general pages with search results. If a User accesses the "Shopping" tab in Google, Bigshopper will not be visible as a CSS partner. Those clicks do not go through Bigshopper CSS either, but through Google CSS. By the way, this applies to all CSS Partners. The margin advantage only applies to all Shopping clicks from Google's normal search results pages (and not to other parts for which the Shopping feed becomes a user, such as remarketing and the Google Shopping tab). CSS Partners must provide each CSS account with an opt-in requested from Google, so that CSS Partners' advertisements are also visible on all other Google products (such as remarketing, the Google Shopping tab, etc.). When switching your account, please make sure that the CSS Partner you choose has requested these opt-ins for each country. Bigshopper has activated all opt-ins in all countries. This also includes the opt-in that your Google account specialist will keep access to your Google Ads account (by default your contact person will lose this access, because a CSS Partner is seen as a competitor of Google, so Google employees are not allowed to have access to those accounts anymore).
 

How do I know which CSS partners are advertising on my behalf in Google Shopping?

As a CSS partner it is possible to create a Google Merchant Center for any domain that is also verified and claimed. This seems unlikely, but that is the practice. This can only be done by Google CSS Partners, you cannot do this yourself with a Google Merchant Center that is not linked to a CSS Partner. Then you can only claim and use a domain name in a Google Merchant Center once. With CSS Partners this works differently. So it is possible that a CSS Partner uses Google Shopping on your behalf without you knowing it. Therefore Google has a dashboard, where you can see which CSS Partner has claimed your domain name and possibly advertises with your products (for example from an affiliate program).

If you want to check this if you are not using a CSS Partner, you can login to your Merchant Center. Then choose "Shopping ads" in the menu on the left and then select Configuration. You will now see a dashboard with all the CSS's that have claimed your domain name and possibly advertise with your products. If you use a CSS, for example Bigshopper CSS, you will no longer see this dashboard in your Google Merchant Center. You can then create a new Google Merchant Center for free (through Google CSS), where you verify and claim your domain name. If you do this, you will not lose your claim of your Merchant Center that falls under Bigshopper CSS (although you can get a warning). After claiming in the Google CSS Merchant Center (which doesn't have to be active) you can see the dashboard with all CSS Partners that might advertise with your products.

If you don't want one or more CSS Partners to claim your domain and possibly advertise with your products, you can disable these Partners through this dashboard. Google indicates that the processing of an unsubscription can take up to 24 hours.
 

Is it better to advertise in Google Shopping via a CSS Partner such as Bigshopper?

The choice is yours, but through a CSS Partner such as Bigshopper, the full bid you set in Google Ads will go into the auction within your Shopping campaign. If you don't use a CSS Partner, Google will keep a 20% margin on your bid and only 80% of your bid will be included in the auction. Competitors who use an auction, automatically bid 25% higher than you do (after all: if you both bid 50 cents in the auction, Google will keep 20% within your Merchant Center. Only 40 cents will enter the auction. You then have to bid 25% to bid 50 cents again, just like your competitor who does use a CSS Partner). If you hardly make any costs in Google Ads, then the advantage is not great and it might not be useful to make the switch. If you spend about 250 euros or more on your Google Shopping, then it certainly pays to make the switch to a CSS Partner.
 

Will I keep my Google contacts after switching to Bigshopper CSS?

If you have been assigned one or more Google contacts, you will keep them after switching to Bigshopper CSS. Bigshopper has signed an opt-in document in which we give permission for Google to retain access to accounts that switch to Bigshopper CSS. Please note that not every CSS has arranged this, so you may lose your contacts with another CSS. Please check with the relevant CSS. Bigshopper has arranged this for all countries.

It is possible that your current contact person cannot request certain components (e.g. beta's), in that case this can be done through 2 fixed contacts at Google that Bigshopper has been assigned.

 

What is the delivery time of products on Bigshopper?

Bigshopper is a price comparator. This means that Bigshopper does not deliver products directly. If you are looking for delivery time or other information about a product, it is best to click through to the supplier of your choice. You may find additional information on that page. If this is not the case, please contact the affiliated webshop directly to request current stock information on products.
 

I use a Google MCA (Multi Client Account), does this have an impact on switching to Bigshopper CSS?

If you use a Google MCA (Multi Client Account) then this means that you have one Google Merchant Center account, which includes multiple sub-accounts. It is no problem to transfer the entire MCA from Google or another CSS to Bigshopper CSS. The only thing that Google does not allow is that the MCA falls under a different CSS than the subaccounts. In that case, the subaccounts that are transferred are separated from the MCA. The solution is then to transfer the entire MCA to Bigshopper. Please note that with multiple accounts and countries the cost of Bigshopper will increase. If an MCA is linked to one country, Bigshopper will ensure that if multiple countries are targeted, the "From Bigshopper" link will be redirected to the correct country, so that visitors will see the correct language/country combination.
 

What data can Bigshopper CSS see when I switch?

To switch to Bigshopper CSS we never need access to your Google Ads account or your data. In most cases (90% of the cases) we can switch your account through an account association switch. Your current Merchant Center will then be converted to Bigshopper CSS. Bigshopper will then not have access to your account (including your Merchant Center). Important: Bigshopper works with many partners, in order to prevent us from being able to view data of possible customers or customers of partners, we have written to Google that we are not allowed to have access to accounts and/or data! Please be aware of this when choosing a CSS Partner, it is possible that not every CSS Partner has indicated this (and has insight into your data!). If new accounts are created by Bigshopper (we will create an account and it is not a matter of switching an existing account), Bigshopper will have access to your Merchant Center. Only the data that is visible there will be accessible to us. If you don't want this, it is possible to create new Google CSS accounts yourself and switch to Bigshopper.
 

What impact can I expect in my account if I switch to Bigshopper CSS?

The expected impact depends on several factors. First of all, after the switch 100% of your bid in your Google Shopping campaigns within Google Ads will go into the auction. That's if you are still with Google CSS only 80%. While keeping your existing bids, a 25% higher bid will enter the auction.

You can reduce your bids by 20% to save costs. In practice, we see that most customers choose to keep their existing bids, in order to achieve a higher display share. Please note that this does not always have a positive effect: if you have very generic campaigns, a higher display share means that you will be visible more often. This can entail extra costs and does not always have to result in an immediate increase in turnover. Keep a close eye on your campaigns and adjust where necessary. In many cases we see a higher display share, making you more visible and more volume with the same bids.

There are a number of exceptions. If you are using smart bidding (e.g. Target ROAS), a switch (both a switch from Google to Bigshopper or vice versa) will restart the learning period. This can cause your campaigns to perform worse in the beginning, because they have to find a balance in the new situation. Another exception occurs in a market with very little competition. You will then notice less difference. You may be visible everywhere, without much competition. The best metric to monitor your results after the switch is display share, but this can still give a distorted picture. After all, if you bid more, you enter the auction within the Shopping campaigns with more words (keywords on which you might not even be visible now). It is possible that the visibility on these new words is limited, so the metric display share can be distorted as well. If you remain visible on the same words, display share is the best metric to see the change.
 

What is the difference between Bigshopper CSS and other CSS Partners?

Bigshopper has many advantages over other CSS Partners (see also the question: "Why Bigshopper CSS?"). Each CSS Partner has a different way of working and a different business model. Ask the CSS Partner in question which model they use and make a choice based on that model.
 

Can I advertise with different CSS Partners?

It is possible to work with multiple CSS Partners at the same time. Google indicates that it will always try to display the same product only once per search from one advertiser. However, Google does indicate that in rare cases (where Google cannot see that it is the same product from the same provider), the same product from the same advertiser may be displayed twice through different CSS Partners. Google also indicates that if multiple CSS Partners are used, this will not be detrimental to the CPC, as the same advertiser cannot compete with himself in the auction. We advise to use only one CSS Partner. There are several CSS Partners that offer to deploy your campaigns (sometimes performance based). They will then buy at the same auction as you do, so there will be competition between the two: either you are visible, or the CSS Partner is advertising on your behalf. Although this does not drive up the CPC, it does ensure that the account with the highest bid is visible (all other factors left unchanged), so that you are no longer fully visible with your own account. We therefore advise you to keep your Google Ads in-house and to choose one CSS Partner. If you want to advertise with multiple Merchant Centers, this is also possible within Bigshopper. We can create unlimited Google Merchant Center accounts for one domain name of your webshop.
 

Where can I see which CSS can advertise with my products (CSS checker / CSS dashboard)?

Every CSS partner has the possibility to claim/verify a domain, even if that CSS partner has not received permission from a webshop. Affiliates can claim any domain name they want and if they have a feed with products, advertise in Google Shopping. Bigshopper does not advertise in Google Shopping on behalf of webshops and does not use affiliate features/models (nor does it advertise with affiliate links). We advise every customer to keep a Google CSS account active in addition to the Bigshopper CSS merchant center. Only in the Google CSS account is a dashboard visible with which CSS's have the possibility to advertise on behalf of a webshop. This Google CSS account will not be used to advertise, but only to disable affiliates and other CSS partners who are not allowed to advertise on your behalf. It is important to know that if you create a Google CSS Merchant Center (and are already with a CSS partner such as Bigshopper), you need to verify it. With a non-Google CSS (such as Bigshopper) you can never lose your account verification and claim. That may seem so, but your Bigshopper CSS Merchant Center will remain claimed.

To clarify how it works:
You use the Bigshopper CSS merchant center account to advertise in Google Shopping.
You use the Google CSS merchant center account to check which CSSs are advertising on your behalf.
In the Bigshopper CSS merchant center account you cannot see which other CSSs are advertising on your behalf. This can only be done through a Google CSS merchant center.
You will always need both. Bigshopper CSS for advertising. Google CSS for unchecking other CSS's.
With a Bigshopper CSS merchant center account you can claim all domains without a verification method.
For a Google CSS GMC account you do need to go through a verification process to claim. The Google CSS merchant center is basically the account with the most rights. Through this account you can choose which CSS's are allowed to advertise a domain.

How to create an additional Google GMC account?
- Create a new Google email address. For example [email protected]
- Use this email address to create a new Google merchant center account at https://www.google.com/retail/solutions/merchant-center/.
- Claim the domain in this Google merchant center. You now get the message that only 1 domain can be claimed. This would imply that the claim of your existing Bigshopper CSS GMC account will be lost. However, you can ignore this message. If all goes well the claim of your Bigshopper CSS merchant center account will be retained.
- In some cases other steps have to be completed (such as uploading the feed), but in practice this is not a requirement for all accounts.

How to delete other CSS's?
Follow all the above steps to create an additional Google Merchant Account
Log in to your CSS checker account (the new Google merchant center)
Click on the tool icon
Go to Configuration of Shopping ads
Go to the CSS tab
Disable the unwanted CSS's.
 

How can I switch back to Google CSS or another CSS Partner?

If you want to switch back to Google or another CSS, this is possible. In most cases Bigshopper gives you a notice period of one calendar month. This means that you will have one full calendar month left on your Bigshopper contract. You may switch back or switch to another CSS Partner before the end of the contract, if you wish. Switches take place daily and a full switch takes about 24 hours. To switch back to Google CSS (or to another Partner) we need a consent mail, in which you indicate that you want to switch back. Please contact the support team of Bigshopper to receive the correct consent mail, if you send that line of text back to us, we can submit your request to Google.
 

Is it possible to become visible on Bigshopper with an affiliate feed?

That is not possible. Bigshopper never works with affiliate feeds in the Netherlands to keep the model fair and transparent. We want traffic that comes in to our paying customers to go to our paying customers and not to forward that traffic to competitors on the basis of affiliate marketing. This does happen with other CSS Partners, but we do not. Only in countries where too few customers are connected (e.g. new countries in which Google Shopping was launched in 2019, such as Greece, Romania, Finland, etc.) are some affiliate feeds used to meet the requirements of the Google CSS Partner program (which requires, among other things, that a minimum of 50 shops are compared in each country). If there are sufficient paying customers in these countries, the affiliate feeds will be removed. For countries such as the Netherlands, Germany, Belgium, etc. no affiliate feeds will be used.
 

What does Premium Google CSS Partner mean?

There are several types of CSS Partners. First of all there is the "Active CSS", this is a CSS that does not meet the strict requirements of Google and therefore is not a Google CSS Partner. Support with this "Active CSS" is minimal. In addition, there is a CSS Partner: this meets the minimum Partner requirements of Google: there are Google Ads certified employees (both Google Fundamentals and Google Shopping exam must be passed), at least 100 customers must use Google CSS and there are requirements regarding the price comparison website (at least 50 connected customers, specific requirements regarding search and filter functions, etc.). A Google CSS Premium Partner meets even stricter requirements and has a minimum of 500 connected customers. This not only concerns 500 customers who are visible on the price comparison website, it concerns 500 customers who have at least been switched within Google Shopping (with a Merchant Center switch). Bigshopper meets all strict requirements and has been a Premium Partner since August 2018. The advantage of a Premium Partner compared to a normal Partner is that there is extra support and that Premium Partners are also invited for specific workshops. If you would like to check the differences, you can do so on the Google CSS Partners page: https://comparisonshoppingpartners.withgoogle.com/become_a_partner/.
 

How do I start at Bigshopper CSS and how long does this process take?

Starting is easy. Contact us and we will send you an order confirmation. If it is digitally signed, we still need a feed (containing all the products we can load on Bigshopper). If you don't have a feed, we can use our API connection to retrieve the product data from your Google Merchant Center. Finally, we need a consent mail. This is a short mail in which you indicate that you are the administrator of the Merchant Center, the mail also contains the ID of your Google Merchant Center and gives you access to switch the account to Bigshopper CSS. Switches can be made on a daily basis. It then takes a maximum of 24 hours on average before you can switch to Bigshopper CSS. If you only want to use Bigshopper without CSS, we only need an order confirmation and a feed.
 

As an online marketing agency or self-employed person, how do I connect my clients to Bigshopper CSS?

Are you a self-employed person, online marketing agency, web builder or other organization that wants to bring multiple customers to Bigshopper CSS, then we work with a partner model. Check out our partner page for more information and affiliated partners. If you are interested, we advise you to contact our Bigshopper support team (this can be done via the partner page, but also via the contact page).
 

Can Bigshopper manage my Google Ads/Google Shopping campaigns?

No, Bigshopper does not manage Google Ads campaigns for customers. Nor does Bigshopper advertise on behalf of clients through affiliate marketing, for example. If you would like to outsource your Google Ads campaigns to an online marketing agency, we advise you to contact one of our partners on the partner page.

Bigshopper does use Google Comparison Listing Ads. These are ads that can and may only be used by comparators. Bigshopper strives for full visibility. This visibility is included in your monthly costs. More information about Comparison Listing Ads can be found at https://support.google.com/google-ads/answer/9262823?hl=en
.
 

What are Comparison Listing Ads and can I use them?

Comparison Listing Ads is a new advertising format from Google Ads, which can only be used by CSS Partners (price comparison companies). These are ads that are visible on an extra tab next to the normal Google Shopping ads (for an example and more explanation see: https://support.google.com/google-ads/answer/9262823?hl=en). Because you can't use these ads yourself, Bigshopper uses these ads. We strive for optimal visibility. This means a high display share and no exclusion keywords. This paid visibility does not involve any extra costs for you, this is included in your monthly fee. Bigshopper deploys Comparison Listing Ads in all countries where this is possible for optimal coverage.
 

What are the costs of connecting a webshop to the Bigshopper CSS?

What Google support can I expect from Bigshopper CSS?

A frequently asked question (especially from large advertisers) concerns support from Google when switching from Google CSS to Bigshopper CSS. Bigshopper is Premium CSS and therefore has support from the Google CSS team for top merchants (and also a dedicated support channel). See also Google's official page about this and the differences between CSS Partners and CSS Premium Partners (such as Bigshopper): https://comparisonshoppingpartners.withgoogle.com/become_a_partner/.

Offices and large customers are often assigned a dedicated account manager from Google. For agencies there are contacts, but for large Google Ads account also (the LCS (Large Customer Sales) support). Officially a Google support employee is no longer allowed in an account of Google Ads and is not allowed to give support as soon as they switch to a CSS Partner. Bigshopper has signed an agreement with Google (the so-called waiver agreement), whereby a Google CSS employee (the normal Google support) is allowed in the account of a non-Google CSS.

The normal support through the help center (in case of problems) remains the same whether you are with Google CSS or a CSS Partner (see also https://support.google.com/google-ads/answer/7218750?hl=en). The extensive support (support for your agency, campaigns, but also e.g. requesting beta's) you keep and you can also request support (through our support) from the Google CSS team. Bigshopper has 2 regular Google CSS contacts who can support customers that fall under Bigshopper CSS. This support is also available for agencies that join Bigshopper as a partner.

For optimal support it is therefore important that the Google waiver document is signed by the CSS Partner you want to use, that there is a Premium CSS Partner (please note: not all CSS Partners are Premium CSS Partners) and also pay attention to the support you receive from the CSS Partner itself. From Bigshopper we can help you with issues with your Google Shopping campaigns, we have multiple support employees who are Google certified for Shopping.
 

What is Surfaces across Google and what should I do if I am disapproved?

Surfaces across Google (also known as Google Platforms) is available in all countries in Europe where Google Shopping is active. Surfaces across Google means that products in the Google Merchant Center may be eligible for display in unpaid listings on Google platforms (such as the Google Shopping tab, Google Search, Google Images, Google Maps and Google Lens). These are therefore free listings. This has been available in Europe since mid-October 2020.

In Europe, given the Google CSS program, it is possible that there are multiple accounts that advertise for one domain (namely through multiple CSS partners). This creates a conflict: the free screenings can only be linked to one Merchant Center. Google automatically grabs the Merchant Center with the most products.

The status of your registration for Google Platforms can be found in the Google Merchant Center under settings > Google Platforms. Do all steps have a green checkmark? Then the products are eligible for free screenings and you don't have to do anything else. Go through all the necessary steps until there are green tick marks. Having problems or want to know more?

Tip: create a CSS Checker

Every CSS partner has the possibility to claim/verify a domain, even if that CSS partner has not received permission from a webshop. CSS partners can therefore claim any domain name they want and advertise it in Google Shopping if they have a feed.

In addition to the Bigshopper CSS Merchant Center, we therefore recommend keeping a Google CSS account active. We call this a CSS checker, because only in this account can you see two important settings:
1. Which CSS-en have the possibility to advertise on behalf of your webshop.
2. Which CSS is used for the program Platforms of Google.

How to create a CSS Checker?
1. Create a new Google email address. For example [email protected]
2. Use this email address to create a new Google Merchant Center account.
3. Claim the domain in this Google Merchant Center account. You now get the message that only one domain can be claimed. You can ignore this message: the claim of your Bigshopper Merchant Center account will be maintained.

Where can I find the CSS settings in the CSS Checker?
Log in to your CSS Checker. Under Settings you can go to "Affiliates & CSS". Then you will see a number of tabs including "CSS and". Here you get an overview of CSS parties who have claimed your domain name. Do you want to prevent affiliates or other CSS parties from advertising your domain name on your behalf? Then turn it off. CAUTION: make sure Bigshopper and Google are always active. You can also select Bigshopper CSS for Platforms from Google.

Many problems
For many Google Merchant Center accounts, the products are rejected for Platforms from Google. A reason is always given and some are common such as:

CSS not selected for this destination
This problem can be solved by selecting Bigshopper for Google Platforms in your CSS Checker (see above). Go to Settings > Affiliates & CSS and click on the CSS tab. If you click on Bigshopper 3 dots will appear on the right, this will open a menu where you can select Bigshopper for Google Platforms (see image above). NOTE: make sure that Bigshopper and Google Shopping are always marked with a green check mark!

Missing product data
Make sure you meet all additional requirements and that your feed is complete. You can read more about it in the Google help center

One domain name with multiple Merchant Center accounts (split by country)
Do you have a single domain name (e.g. a .com domain) that serves multiple countries from multiple Google Merchant Center accounts? (One Merchant Center per country for the same domain). Please contact us, we can make sure that instead of multiple options, only one option emerges for Google platforms within your account.
 

My domain name is going to change, can I change my domain name in my Merchant Center?

Within CSS Partners such as Bigshopper, a Merchant Center account is automatically verified and claimed. Unlike via Google CSS, where it must be demonstrated that you are the owner of a Merchant Center (through verification). However, it is not possible to change the domain name (which is automatically claimed and verified) with a CSS Partner, for example if there is a name change. Should this be the case, please contact us. We ensure that the right people within Google change the domain name to avoid downtime of your account. This applies only if the entire domain name changes in terms of name.
 

Is it possible to load products via the Google API?

It is possible (for example if there is no feed available) to load the products via the Google Content API. This API link retrieves the products from the Google Merchant Center and imports them daily to Bigshopper. To create the link, the Google Merchant Center needs access to a specific Bigshopper API mail address (the exact mail address can be requested from our support department). In combination with the ID of the Merchant Center we can then retrieve all products and make them visible on Bigshopper.
