Why Product Reviews Matter for Google Shopping
If you’re running Google Shopping Ads, product reviews aren’t just a nice-to-have—they’re a performance multiplier. For e-commerce brands, especially on platforms like Shopify and WooCommerce, reviews directly influence click-through rates (CTR), trust, and even conversion rates.
When users scroll through Shopping results, listings with star ratings stand out immediately. A 4.7-star rating with 100+ reviews signals credibility in a way no discount or title tweak can. This is why review syndication and proper Merchant Center integration are crucial to your Google Shopping performance.
How Reviews Appear in Google Shopping
When set up correctly, your product reviews can appear as star ratings directly in your Google Shopping ads. These stars are sourced via the Product Ratings program and depend on feeds submitted to Google by approved review aggregators.
Example:
Ad A (no reviews): “Running Shoes – $79.99”
Ad B (with reviews): “Running Shoes – $79.99 – ⭐ 4.8 (254 reviews)”
Guess which one gets the click?

Benefits of implementing Product Reviews in Google Shopping
Higher Click-Through Rates
Ads with stars are visually more attractive and trustworthy, especially when users compare several products side-by-side.
Increased Conversion Rates
Social proof from reviews helps reduce buyer hesitation. A product with high ratings is perceived as lower risk.
Improved Quality Score
More engagement (clicks) and higher conversion rates can improve your ad relevance result in higher ROAS if you add Product Reviews in Google Shopping ads.
How to Get Product Ratings on Google Shopping
Enroll in Google’s Product Ratings Program
You must either submit your own review feed or work with an approved review aggregator (like Loox, Judge.me, Yotpo, or Trustpilot).
Collect Reviews Actively
Send post-purchase review requests via email
Offer incentives (discounts, loyalty points) for submitting reviews
Use review apps that sync directly with Google Shopping feeds
Meet Minimum Thresholds
Google requires at least 50 reviews across all products in your feed to display star ratings.
Use Structured Data (If Applicable)
If you also run a product-rich website, adding schema.org structured data can help Google crawl reviews directly from your site.

Reviews Not Showing in Ads
You’re under the 50-review threshold
