Online reviews aren’t just customer feedback — they’re a performance lever. In Google Shopping, they can dramatically impact how your products are perceived and how well they sell. Yet too often, sellers miss opportunities simply because they don’t understand the system.
Here’s what you need to know to harness the full potential of review stars in Google Shopping.
We break down how Google Shopping reviews operate, how to get your stars to show up, and why they sometimes don't, with clear steps to help you make the most of this valuable marketing asset.
Seller Ratings vs. Product Ratings: Know the Difference
Google shows two types of reviews — and they serve different purposes:
Seller Ratings
- Focus on your business as a whole.
- Reflect customer experiences with shipping, service, and support.
- Appear in search ads, Shopping ads, and Google’s seller listings.
Product Ratings
- Focus on individual product performance and quality.
- Appear as 1–5 stars in both paid and free listings.
- Consolidate reviews from across the web, not just your site.
Why It Matters:
Confusing these can lead to misaligned expectations. Seller Ratings build trust in your brand. Product Ratings help sell the specific item.
How to Get Product Reviews Showing in Google Shopping
Activating review stars in Google Shopping requires a few deliberate steps. Here’s the checklist:
1. Activate the Product Ratings Program
- Log in to Google Merchant Center.
- Opt into the Product Ratings Program under “Growth” > “Manage programs.”
2. Hit the 50 Review Minimum
- You must have at least 50 product reviews across your catalog (not per product) to be eligible.
3. Submit Reviews Correctly
- Via Aggregator: Use a Google-approved aggregator (like Trustpilot, Yotpo, etc.) to submit reviews automatically.
- Manual Upload: If you gather reviews yourself, submit a product review feed (XML format) at least once a month.
4. Provide GTINs (Global Trade Item Numbers)
- GTINs are Google’s preferred method to match reviews to products.
- Missing GTINs? Google will attempt a match using SKUs, Brand + MPN combinations, or product URLs — but this is less reliable.
Why the Review Count You See on Google Might Not Match Your Website
Don’t panic if numbers don’t align.
Google aggregates reviews from across multiple sources, not just your website. Reviews tied to a specific GTIN are pooled across sellers, meaning another retailer’s customer feedback can affect the review count you see on Google Shopping.
Key Takeaway:
The review count is a shared reflection of the product’s reputation, not just your brand.
Why Your Reviews Might Not Be Showing in Search (and How to Fix It)
Even with the right setup, your reviews might not appear. Here's why — and how to troubleshoot:
1. Relevance and Quality Standards
- Reviews must be considered helpful and relevant by Google’s algorithms.
- Thin, low-quality, or spammy reviews are often filtered out.
2. Incomplete or Incorrect Product Data
- GTINs, SKUs, brand names, and MPNs must be correct and consistently formatted.
- Errors or omissions disrupt the matching process, causing reviews not to link properly.
3. Insufficient Number of Reviews
- Google may suppress star ratings until a product has "enough" reviews to present a credible average.
- “Enough” is a moving target, depending on your product category and competition.
4. Review Feed Issues
- If you’re submitting your feed, check for upload errors.
- Use the Product Reviews Diagnostics tool in Merchant Center to spot invalid entries, missing data, or schema mistakes.
Pro Tips To Maximise Your Review Visibility
- Keep Product Data Clean and Updated: GTINs, SKUs, MPNs, and URLs must be accurate.
- Encourage Early Reviews: Post-purchase emails, loyalty incentives, and seamless review collection methods help build volume fast.
- Use a Trusted Aggregator: They simplify compliance and feed management.
- Monitor Diagnostics Regularly: Small errors compound over time if unchecked.
- Focus on Quality: Authentic, detailed reviews (especially with photos) are favoured.
Stars Sell — But Only If You Earn Them
Review stars aren’t just a vanity metric.
They directly impact visibility, click-through rates, and conversions. By understanding how Google Shopping treats reviews and proactively managing your review program, you can position your products (and your brand) to stand out when it matters most: at the moment of decision.
