This is how your Shopping listing looks after the switch.
Google takes a margin off every bid before it reaches the Shopping auction. Through a Comparison Shopping Service your whole bid goes in instead. The arrangement exists because the European Commission required Google to open Shopping to other services, so this is not a discount we invented. It is how the auction works in Europe.
In Google's own words
You approve the switch yourself, inside your own Merchant Center.
“admins of the Merchant Center account are notified of your request and can approve or decline the request in their Merchant Center account”
You can turn us off again, and it takes effect within a day.
“Opt-outs may take up to 24 hours to become effective”
Google reviews every CSS regularly and can suspend one that fails.
“All websites registered with the CSS programme are periodically reviewed to ensure that they meet the minimum requirements”
Your Merchant Center ID is an account number, not a password. We use it to send you a request. Nothing happens until you approve it inside Google, and you decide what access we get. You can set it to none.

With us, the same clicks can cost up to this amount less
+680 €
Google's own CSS keeps up to 20% of your bid. Of every €10 you bid, only €8 used to reach the auction. Now the full amount does, so the same place can cost up to 20% less.
This calculation is an illustrative example based on a 20% margin. Your actual results always depend on the market, feed quality and competition.

Frequently asked questions
Will I have any downtime?
No. The migration happens on Google's side of the setup while your campaigns keep running. There is zero downtime, and your ads do not stop for a moment.
Do I lose my history?
No. All of your data history is kept. Account, campaigns, budgets and learning data are untouched: we only change the service your Shopping ads are bid through.
How do I cancel?
With a single email. There is no lock-in period, and you can always move back to Google's own CSS at no charge.
What will shoppers see under my ads after the switch?
The same ad, with one name changed. The grey line under each Shopping ad names the CSS that submitted it: "By Google" before the switch and "By Gezar" after it, because Gezar is the company that runs The CSS Partner. Your products, prices, images and titles stay as they are.
Does it work with Performance Max?
Yes, for the Shopping part of the campaign. The rest of Performance Max runs as before, and you change nothing in the campaign itself, because the switch happens in Merchant Center.
How can I tell that it works?
Compare impression share on Shopping before and after, not average cost per click, and leave the first seven days out while the switch settles. The "How it works" page explains which number shows the effect most directly.
