Google Shopping CSS partners: save 20% on CPC in Europe
Comparison Shopping Services can lower your Shopping ad costs in the EU. Here's how it works and whether it's worth it.
In the European Economic Area, Google is required to allow Comparison Shopping Services (CSS) to compete on equal terms for Shopping ad placements. Merchants who switch from Google's own CSS to a third-party CSS partner get a roughly 20% discount on cost-per-click.
Same ads. Same placements. Lower cost. Here's how it works.
How the discount works
When you bid through Google's own CSS ("Google Shopping"), Google adds a margin to your CPC. Third-party CSS partners don't add this margin. The same bid goes further. Your effective CPC drops by about 20%.
Who this applies to
Only merchants targeting EEA countries (EU member states, Norway, Iceland, Liechtenstein) and the UK. Merchants targeting only the US, Canada, or other non-EEA markets see no difference.
Is it worth switching?
The math is straightforward:
| Monthly EU Shopping Spend | Estimated Monthly Savings |
|---|---|
| 5,000 EUR | ~1,000 EUR |
| 10,000 EUR | ~2,000 EUR |
| 50,000 EUR | ~10,000 EUR |
The switch is free with most CSS partners. They make money from the Google referral, not from you.
Popular CSS partners

Kelkoo,
Idealo, and
