After switching from Google Shopping CSS to PriceRadar CSS, your bids become more efficient — but how do you actually measure the impact inside your Google Ads account?
Here’s what changes and how to evaluate performance.
What changes after switching to PriceRadar CSS?
With Google CSS, part of your bid does not fully enter the auction. When you switch to PriceRadar CSS, this margin is removed.
The result: 100% of your bid participates in the auction, leading to:
Higher visibility (more impressions), or
Better efficiency (lower CPC / higher ROAS)
Impact on Manual CPC campaigns
Keep bids the same
Your average CPC stays similar, but impressions and clicks increase due to stronger auction participation.
Lower your bids
Your CPC decreases while maintaining similar traffic levels. In many cases, you achieve the same volume at lower cost.
Impact on automated bidding (Target ROAS / Performance Max)
Same ROAS target
Google uses your full bid more effectively, typically resulting in:
Higher conversion value
More revenue at the same ROAS
Higher ROAS target
You can increase your ROAS target and still maintain performance, leading to:
Improved profitability
Stable impressions and conversions
Note: automated strategies need 2–4 weeks to fully stabilise after switching CSS.
