How review schema markup matters in SEO
Showcase reviews and ratings
One of the main advantages of review schema markup is that you can display your reviews and ratings on SERP and local search results. This allows users to learn more about your brand and services without having to visit your site.
Enhanced Visibility in SERPs
As you showcase genuine reviews and ratings, this increases the chances of appearing as rich results or featured snippets.
Helps build trust
Getting reviews and ratings from real customers and showing them on search results builds trust. Supporting the reviews by adding the reviewer’s name and other markup elements boosts their validity further. This allows potential customers to know what others are thinking about your brand.
Increased Conversions
Getting positive reviews is good for a brand in the long term. Whenever users see positive reviews for your brand on search results, they are more likely to proceed with a purchase and convert.

How to Implement Review Schema on Your Site
Now that you know what a service review schema is, let’s discuss the series of steps involved in implementing a review schema on your site.
Determine The Properties to Use
When learning how to build review schema, you must choose from any of the two types, which are: Review Schema and AggregateRating. Both are different types of structured data markup that enable search engines to understand reviews and display them in the SERPs. Review Schema provides information about individual reviews, while AggregateRating provides information about the overall rating of a product or service based on the reviews.
Create The Review Schema
You can create a product review schema markup by using various tools such as Schema.dev or the Schema Builder for Structured Data browser extension to mark up the relevant elements on your page. If you want to create the code manually, you can do that by adding the schema markup in the HTML code and making modifications.
Choose the specific webpage to generate a review schema, and then open the extension. Choose the “Review” tab under the “All Supported Schemas (36) section.”
Upon clicking Review, you will be presented with various properties as shown below:
Choose the property you want and mark the important data on the page. For eg, if you want to select the author of an article, select the “Author” property and then click on the arrow button to select the block on your page with the review author’s name.
After marking up the information, copy the code by clicking on “View Markup”.
Add the Review Schema to Your Website
Understanding how to add review schema isn’t that hard. Once the code is generated, it must be added to your site. Paste the code inside a <script> tag in the <head> or before the closing </body> tag. If you’re using a CMS, you can add the review schema using dedicated plugins like Yoast SEO, Schema Pro, etc.
ValidateThe Review Schema
You must ensure that the review schema is displayed correctly without issues. If you want to know how to test your review schema, you can utilize the Schema Markup validator tool offered by the Schema.org community. Open the tool and switch to the Code snippet tab. After that, paste your code and click “Run test.”
If there are any errors in the structured data, the tool will display them in the results. You can also use Google’s Rich Results Test tool to test whether the search engine crawlers can detect and understand your schema markup. After the testing phase, implement it and start measuring the overall impact with tools such as Google Search Console, Semrush, etc.
Best Practices for Creating Review Schema Markup
Once you learn how to implement review schema, you can significantly enhance your webpage content’s online visibility in search results. However, there are various review schema best practices which you have to adhere to ensure the effectiveness of your review schema. Here we list some guidelines which you must follow for the best results.
Include Genuine Content
One of the best review schema best practices is ensuring that you have included genuine content written by users rather than AI-generated content. Promoting fabricated content results in penalties and degrades trust.
Add Markup That Only Users Can See
When including markup, make sure to add the ones that are visible to users. Adding schema markup for hidden content is misleading and results in penalties.
Be Specific
Your Google product structured data must be specific and should include reviews related to the particular product, not the overall brand and other products.

If you are trying to implement a service review schema, the entire process is detailed in this article step by step.
