CSS vs. Google Shopping direct
Both routes place your products in the Google Shopping auction. The difference is in the price you pay per click — and who profits from your margin.
Google Shopping is itself a Comparison Shopping Service (CSS) inside the EU. Whether you book it directly or through a certified CSS partner, the same auction decides which ad is shown.
The crucial detail: Google keeps roughly 20 % of your maximum bid as its own margin when you use Google Shopping direct. A CSS partner passes the full bid into the auction.
Google Shopping direct
You manage everything inside Google Ads. Setup is familiar and onboarding is fast.
The trade-off: Google deducts about 20 % from your bid before it enters the auction. You pay full price, but bid with reduced power.
Google CSS partner
A certified CSS partner like csspartner.io uploads your feed and runs Shopping campaigns on your behalf — without that 20 % margin.
Effect: with the same budget you bid up to 20 % higher, win more auctions and pay less per click. Nothing changes for your shop or your customers.
Who should switch?
From around 200 € monthly Google Shopping spend the saving already exceeds the flat CSS fee. The bigger your budget, the bigger the gap in your favour.
If you do not run Shopping campaigns at all yet, start with a CSS partner from day one — you keep the full bidding power right away.
