Free Comparison Shopping Service

We're a certified Google CSS partner

A Google-certified CSS partner is a third-party Comparison Shopping Service authorised and verified by Google to place Shopping ads on behalf of retailers. Partners don't add the 20% commission that Google's own CSS charges, making your bids more competitive.

Following European Union antitrust decisions, and the ruling of court cases against Google's dominant position in the search market, retailers can advertise through other CSS providers and potentially reduce their advertising costs.

Isn't Google's CSS the best?

Lots of retailers assume that Google's own CSS is the best option, but that's not always the case. Relying solely on Google's CSS can come with hidden costs and missed opportunities.

By default, 20% of the cost for every Google Shopping click goes to Google in commission fees for providing its CSS. That's 20% of your Google Shopping budget that's lost on fees.

Third-party providers enable you to eliminate that cost, but it's often replaced with a monthly fee, also eating into your earnings.

We're a Google-certified CSS provider, but we've decided to keep our Google CSS service free, so you get 100% of your media budget and 100% of your profit.

Why Bidnamic's CSS?

We're a Google-certified CSS partner, but we offer our CSS service completely free.
No hidden costs, no monthly subscriptions, and no commission charges.

Frequently asked questions

What is a Google-certified CSS partner?

How does the 20% saving work?

Google deducts 20% when bidding on its own CSS. Partners like us avoid this deduction, helping you improve visibility for your ads without increasing your ad budget.

Who can use Bidnamic's CSS?

Any retailer advertising in the UK or other EEA countries can use Bidnamic’s CSS. There’s no requirement to be an existing Bidnamic client.

How long does migration take?

Most merchants see “CSS: Bidnamic” in Merchant Center within one working day of accepting our invite. Some providers may impose a 14-day grace period.

Will switching providers affect my data or ad delivery?

No. Your product IDs, performance data, and Shopping campaign structure remain intact. The only visible change is the “By Bidnamic” label beneath your ads on Shopping.

Can I switch back to Google's CSS or another provider?

Yes. If you decide Bidnamic’s CSS isn’t for you, simply request a transfer back at any time with no penalties or downtime.
