Did you know that Google Shopping ads with product ratings see a 15% higher click-through rate (CTR) than those without? That’s because star ratings provide immediate social proof, reassuring potential buyers that the product has been purchased and reviewed by others.

If you’re running an eCommerce business and leveraging Google Shopping Ads, incorporating product ratings is a must to increase visibility and conversions. However, ensuring your ratings appear correctly requires proper setup.

This guide will walk you through how to display ratings in Google Shopping Ads, troubleshoot common issues, and optimize your setup with Lipscore.

👉 Want to know if your ratings are showing? Start by searching for one of your own products in Google Shopping!

Requirements for Displaying Product Ratings

Before your product ratings can appear, Google has specific criteria that must be met. Here’s what you need:

• A minimum of 50 ratings across all products in your catalog.
• At least 3 ratings per individual product for that product’s star rating to appear.
• Authentic, up-to-date ratings—Google recommends refreshing rating data at least once a month, but ideally every 24 hours for real-time accuracy.
• GTIN (Global Trade Item Number) or other structured data must be included to match your product with Google’s database.
• If your products don’t have GTINs, don’t worry! We’ll cover an alternative method below.

How to Verify Your Ratings on Google Shopping Ads

Wondering if your ratings are visible in Google Shopping? Follow these steps:

1. Search for Your Product in Google Shopping:
   • Use Google Search and go to the “Shopping” tab.
   • Look for a star rating under your product title.
   • If ratings appear, your setup is correct!
2. Check Google Merchant Center:
   • Navigate to the Product Ratings section of your Merchant Center account.
   • If your ratings aren’t displaying, move to the troubleshooting section below.
3. Confirm the Lipscore Rating Widget is Active:
   • The Lipscore-rating widget must be properly implemented on your product pages.
   • If the widget is not detected, Google may not be able to pull the necessary structured data.

💡 PRO TIP: If your products have at least 15 reviews but no rating stars in Google Shopping, double-check your feed submission settings.

What If Your Ratings Aren’t Showing in Google Shopping Ads?

If your star rating is missing from Google Shopping, you can either follow the “Simple Method” or the “Advanced Method.”

The Simple Method

If your product ratings aren’t appearing, don’t panic. There are two main methods to fix this:

The Simple Method (For Most Businesses)

If your business already has GTINs assigned to each product, follow these steps:

Eligibility Check:

• Log in to Google Merchant Center and verify that the “Product Ratings” program is activated.
• If not, request access and follow Google’s verification process.

Check Your Lipscore Feed:

• Ensure your Lipscore XML feed is correctly formatted and includes GTINs.
• Make sure the rating widget is embedded on your product pages.

Connect Lipscore to Google Merchant Center:

• Upload your Lipscore XML feed to Google Merchant Center as an additional feed.
• Find step-by-step instructions in Lipscore’s Knowledge Base.

Wait for Google Approval:

• Google typically takes 2-4 weeks to approve and display ratings in Shopping Ads.

If your products still don’t show ratings, move to the Advanced Method below.

The Advanced Method (For Products Without GTINs)

For products that don’t have GTINs, such as custom-made goods, legacy items, or private-label products, you’ll need an alternative way to link your ratings to Google Shopping.

How Fullstakk Can Help:

If your GTINs are missing, our partner Fullstakk can merge data from:

• Your Google Shopping feed
• Lipscore’s rating database (via API queries)

This custom data feed is then submitted to Google Merchant Center to ensure your ratings display properly. The level of customization depends on your CMS and eCommerce platform (Shopify, Magento, WooCommerce, etc.).

📌 EXAMPLE:
A retailer using WooCommerce had missing GTINs for half of their products. Fullstakk merged SKU data with Lipscore’s verified reviews, enabling ratings to appear in Google Shopping, leading to a 27% increase in ad CTR.
