How to add star ratings to Google search

Star ratings in Google search results — also called rich snippets — make your listing stand out and improve click-through rates. Here’s how to get them.

The universal snippet

Vouchnest can generate the structured data you need automatically. Enable schema generation in your dashboard and the correct JSON-LD appears on your wall and embed pages.

Example JSON-LD schema

{
  "@context": "https://schema.org",
  "@type": "Product",
  "name": "Your Product",
  "aggregateRating": {
    "@type": "AggregateRating",
    "ratingValue": "4.8",
    "bestRating": "5",
    "worstRating": "1",
    "reviewCount": "124"
  }
}

Automatic schema

Vouchnest can generate and update review schema automatically as you approve new testimonials.

Works for products & services

Support for Product, Service, and LocalBusiness schema types — whatever fits your business.

Test with Google tools

Use Google's Rich Results Test to validate your markup before it goes live.

Schema without code

Vouchnest can inject schema markup directly into your hosted wall page at vouchnest.com/wall/your-space-slug. If you link to that page from your site, Google can crawl it and discover your review data for rich snippet eligibility.

Frequently asked questions

How long does it take for stars to appear?+

After implementing valid schema markup, Google can take anywhere from a few days to several weeks to recrawl your pages and display star ratings. Use the URL Inspection tool in Google Search Console to request an immediate crawl.

Do I need to be verified?+

For review schema on your own site, no verification is needed beyond owning the domain. For Google Seller Ratings in ads, you need a verified Google My Business profile and a Google Merchant Center account.

Can I add star ratings without reviews?+

No. Google's guidelines require that aggregate ratings be based on real customer reviews. Fabricating ratings or using schema without actual reviews can result in a manual action penalty. Collect genuine testimonials first with Vouchnest, then add the schema.

Will it help my SEO?+

Star ratings are a rich snippet enhancement that can improve click-through rates from search results. While they aren't a direct ranking factor, higher CTR can indirectly benefit your SEO performance over time.

What if Google shows wrong ratings?+

If Google displays an incorrect star rating, first validate your schema markup using the Rich Results Test. Check that your aggregateRating values match what's in your Vouchnest dashboard. If the data is correct, request a recrawl via Google Search Console.
