Introduction

Ever wondered how some websites show stars and ratings right in the search results? That’s the magic of schema markup—specifically for product reviews and ratings.

If you’re running an eCommerce store, affiliate blog, or product comparison site, adding this markup is like rolling out the red carpet for search engines. It increases credibility before visitors even click, in addition to making your results stand out.

What Is Schema Markup?

Definition and Context

Schema markup is one type of structured data that you may incorporate into your HTML. It helps search engines like Google understand what your content is about in a more detailed way.

How It Helps Search Engines Understand Your Content
Think of it as translating your product page into a language Google understands. Your review section is simply words without it. With it, Google knows you’re showing:

A 4.5-star product
Based on 300 reviews
Priced at $39.99

Benefits of Using Schema for Reviews and Ratings

Enhanced Visibility in SERPs
Schema helps your page qualify for rich snippets, which means those eye-catching stars under your listing.

Rich Snippets with Stars and Reviews
These stars instantly build trust and can increase your listing’s real estate on the page.

Boosted Click-Through Rates (CTR)
A better-looking listing = more clicks. Some sites report a 20–30% increase in CTR after implementing review schema.

Types of Schema Markup for Reviews

Product Schema
This marks up product details like name, description, price, brand, etc.

Review Schema
This focuses on the actual content of the review—what the customer said, who said it, and when.

AggregateRating Schema
Used to show average ratings from multiple reviews. This is what triggers the star rating in Google.

Nested Schema in Product Pages
You can combine these types into one JSON-LD block so Google sees the full picture.

How to Add Review and Rating Schema Markup

Using JSON-LD Format (Recommended by Google)
Here’s a basic example:

json

CopyEdit

{

“@context”: “https://schema.org/”,

“@type”: “Product”,

“name”: “Wireless Headphones X200”,

“image”: “https://example.com/images/x200.jpg”,

“description” : “High-quality wireless headphones with noise cancellation.” ,

“review”: {

“@type”: “Review”,

“author”: “Jane Doe”,

“datePublished”: “2024-07-01”,

“reviewBody” : “Amazing sound and battery life!” ,

“reviewRating”: {

“@type”: “Rating”,

“ratingValue”: “5”,

“bestRating”: “5”

}

“aggregateRating”: {

“@type”: “AggregateRating”,

“ratingValue”: “4.7”,

“reviewCount”: “274”

}

Place this in the <head> of your product page.

Manual HTML Microdata
Not recommended unless you can’t use JSON-LD. More prone to errors and less flexible.

WordPress and Shopify Plugins

Use tools like:

Rank Math
Schema Pro
Shopify’s built-in Product Reviews app with schema support

Best Practices for Review and Rating Schema

Use Authentic and Visible Reviews
Google requires that the reviews you mark up are actually visible to users. No behind-the-scenes tricks.

Use the Correct Schema Types
Follow Google’s official documentation.

Keep Content Updated
Outdated reviews may not reflect your current product. Update your markup frequently or use dynamic schema.

Common Mistakes to Avoid

Reviews that are not on the page should not be marked up.
Avoid duplicate reviews across pages
Don’t use fake or biased reviews—Google might penalize you

Case Study: Boosting CTR with Review Schema

A tech gadget eCommerce site added review schema to 50 product pages.

Before: Avg. CTR was 4.2%
After (1 month): Avg. CTR jumped to 6.9%
Bonus: Time on page increased as users landed with higher expectations.

How Google Uses Review Schema in Search

Google may display:

Stars
Review count
Average rating

But it’s selective. If the schema isn’t high quality or violates guidelines, it won’t show up.

Schema for Multiple Products or Listings

If you’re listing multiple products on one page (e.g., collection or category pages), you need:

ItemList schema
Nested Product schema within each item

Avoid marking up the entire page as one product.
