Google Seller Ratings
A Google Ads extension displaying a merchant's star rating directly in paid ads, aggregated from reviews collected on Google-approved partner platforms.
Full definition
Google Seller Ratings (GSR) are an automatic Google Ads extension that displays a merchant's average rating directly beneath their text or Shopping ads. These gold stars (1 to 5) are calculated from reviews collected on Google-approved partner platforms: Trustpilot, Avis Vérifiés, Shopper Approved, and around thirty others.
To be eligible, a merchant must accumulate at least 100 unique reviews over the past 12 months and maintain a rating of at least 3.5/5. The extension activates automatically in Google Merchant Center once these conditions are met, with no additional configuration required. GSR appear in Google Search ads, Google Shopping, and Performance Max campaigns when Google determines the display is relevant.
The impact on advertising performance is significant. Ads featuring GSR stars achieve an average of 17% additional clicks at a comparable cost per click. This CTR improvement mechanically reduces CPA (cost per acquisition) by generating more conversions with the same budget. GSR thus constitute a genuine advertising performance lever, directly linked to the review collection strategy.
Concrete example
A cosmetics merchant spends 15,000 euros per month on Google Ads with a CTR of 3.2%. After activating Google Seller Ratings (achieved by reaching 100 reviews on Avis Vérifiés in 4 months), the CTR rises to 3.7%, generating 15% additional clicks without increasing the budget. At an equivalent conversion rate, this represents an estimated 8,000 euros in additional monthly revenue.
On Google Shopping, product tiles displaying GSR stars stand out visually in a competitive feed. Buyers who see the 4.9/5 rating with 250 reviews before even clicking the ad arrive on the site with high confidence, improving post-click conversion rates by 22% compared to ads without stars.
With Review Collect
Review Collect accelerates reaching the Google Seller Ratings eligibility threshold through its multichannel post-purchase campaigns. The 40% WhatsApp conversion rate enables most merchants to reach 100 reviews within 4 to 8 weeks, compared to 12 to 18 months for organic collection without a dedicated tool.
Reviews are automatically distributed to Google-approved partner platforms (Trustpilot, Avis Vérifiés), directly feeding the GSR calculation. The 4.9/5 rating achieved by Review Collect customers maximizes visual impact in ads and trust generated among potential buyers.
