Structured data is a standardized markup format that helps search engines better understand your page content. With schema markup, you can display your customer reviews directly in Google search results.

Structured data is a standardized markup language that precisely describes web page content to search engines. Using the Schema.org vocabulary, it provides semantic context that indexing robots can easily interpret.
Specifically, structured data consists of code snippets (typically in JSON-LD format) inserted into a page's HTML code. These tags tell Google and other search engines the exact nature of the information present: product, review, business, event, recipe, FAQ, etc.
Schema markup for customer reviews is particularly powerful. It allows you to indicate to search engines the ratings given, the number of reviews collected, and the text of testimonials. This information can then be displayed directly in search results as rich snippets.
Implementing structured data for reviews offers considerable advantages for your online visibility and SEO performance:
Rich snippets in Google results: Yellow stars and average ratings displayed directly in SERPs attract attention and significantly increase click-through rate (CTR). Studies show that results with rich snippets generate up to 30% more clicks.
Improved SEO: Google values sites that facilitate understanding of their content. Structured data contributes to better indexing and can positively influence rankings.
Increased trust: Displaying ratings directly in search results strengthens your business credibility before the user even visits your site.
Eligibility for enhanced features: Beyond stars, structured data can enable display in knowledge panels, product carousels, and other enhanced formats.
Technical implementation of structured data requires following Schema.org standards and Google guidelines:
Choose the right schema type: For reviews, the main types are AggregateRating (average rating), Review (individual review), and Product or LocalBusiness depending on your context. These schemas can be nested for a complete description.
Use JSON-LD format: Google recommends the JSON-LD format for structured data. This format, placed in a script tag, is easy to implement and maintain without modifying visible HTML code.
Follow Google guidelines: Displayed reviews must be authentic and come from real customers. Google penalizes sites that display misleading structured data or artificial reviews.
Validate with Google tools: The Rich Results Test tool verifies that your structured data is correctly implemented and eligible for rich snippets.
