You’ll find that CSS partners are widely recognised as improving Shopping Ads performance by increasing effective bid competitiveness.
If you're still unsure, we'd like to invite you to test it for yourself. Contact us to get started.
How does a CSS partner improve my return?
In the EU and UK, Google applies a margin to Shopping Ads bids placed directly through its own comparison shopping service.
This means:
- A £1.00 bid via Google enters the auction as ~£0.80
- A £1.00 bid via a CSS partner enters as the full £1.00
That’s a ~25% relative advantage in auction competitiveness.
In practical terms, this can result in:
✅ Lower cost-per-click (CPC) for the same traffic
✅ Improved ad visibility and impression share
✅ More efficient use of your existing budget
✅ Stronger overall return on ad spend (ROAS)
This is not a workaround or optimisation tactic - it is how the system is designed to work.
How does the setup work?
Switching to Price Pilot CSS is simple and does not disrupt your existing setup.

Why does this advantage exist?
The CSS model exists as a result of a major antitrust ruling by the European Commission.
In 2017, the European Commission fined Google €2.42 billion for abusing its dominant position by favouring its own comparison shopping service in search results.
As part of the ruling, Google was required to open up Shopping Ads to external comparison shopping services (CSS partners), creating a more competitive ecosystem.
To enable this:
- Google applies a margin to bids placed through its own CSS
- External CSS partners are allowed to submit bids without this margin
This structural difference is what creates the ~20% advantage for advertisers using a CSS partner.
