Already running Google Shopping ads? Move to the Dotidot CSS Program and your bids reach the auction at full weight. Same campaigns, same control, lower cost per click.
Included with your Dotidot subscription. No setup on your side.

Google takes a margin from every Shopping bid before it reaches the auction. A certified Comparison Shopping Service submits the same ads without that margin.
20% of every bid is gone before the auction starts.
The whole bid reaches the auction.
You keep running campaigns in your own Google Ads account — same interface, same budgets, same bidding strategies. We never touch them.
The margin Google keeps today stays in your budget instead.
Your campaigns, your budgets, your products. Nothing leaves your Google Ads account.
We connect your Merchant Center and run the migration for you.

All three formats run through the same connection.

On the call we check whether your setup qualifies.
Enter your monthly Google Shopping spend and your average cost per click.
The 20% is an advantage in the weight of your bid in Google's second-price auction, not a guaranteed discount on your invoice. The real effect depends on competition in the auction, your bidding strategy and query volume.

CSS stands for Comparison Shopping Service — a Google partner allowed to submit Shopping ads on behalf of merchants. Through a certified CSS, the margin Google normally takes from every bid does not apply.
Nothing. They keep running in your Google Ads account with the same budgets, products and bids. Only the service that submits them changes.
Yes. Google allows several CSS partners at the same time and deduplicates bids at merchant level, so they never compete with each other.
It can take a few days from the moment we get access. Your campaigns are never paused during it.
