How Review Schema Generator Works

This tool collects the key fields that Schema.org expects for a Review and optionally an AggregateRating. It then assembles a structured JSON-LD object using safe defaults and only includes optional properties when you provide a value. The result is a single script block that can be embedded into any HTML page or templating system.

Step-by-Step

• 1) Choose the item type: Select whether the review is about a Product, Service, LocalBusiness, SoftwareApplication, or Book.
• 2) Fill in item details: Provide the reviewed item name and optional URL, image, brand, SKU, or price where relevant.
• 3) Add review information: Enter the author name, review title, review body, and the star rating value.
• 4) Add aggregate rating (optional): If your page shows an overall rating and count from multiple reviews, add review count and (optionally) best/worst rating bounds.
• 5) Generate JSON-LD: Click Generate to produce formatted JSON-LD (with an optional script wrapper) ready to copy or download.

Key Features

JSON-LD output formatted for readability

The generator outputs neatly indented JSON so you can audit fields quickly, troubleshoot validation warnings, and keep a consistent format across pages.

Supports common reviewed item types

Review schema can describe many things, but most sites need a handful of practical types. This tool supports Product, Service, LocalBusiness, SoftwareApplication, and Book with sensible defaults for each.

Optional aggregate rating for rating snippets

If your page displays an overall rating calculated from multiple reviews, you can include aggregateRating with a review count. This provides stronger structure for search engines when it matches what visitors can see on the page.

Safe optional fields

Not every page has a SKU, brand, or price. The tool only adds these properties when you provide values, helping you avoid empty keys that can trigger warnings or confusion in debugging tools.

Copy and download actions built-in

After generation you can copy the markup to your clipboard or download it as a plain text file. This is useful when moving schema between environments, clients, or CMS templates.

Use Cases

• Ecommerce product pages: Add a review object and aggregate rating that matches the product’s visible star rating and review count.
• Service landing pages: Mark up testimonials or editorial reviews about a service offering, including author and rating.
• Local business profiles: Describe reviews for a venue or business page, with optional URL and image references.
• Software directories: Publish structured reviews for apps, plugins, and SaaS products with clear rating bounds and review text.
• Book review blogs: Add review schema to editorial content about books, including review title and publication date.
• Agency workflows: Standardize schema creation across clients, ensuring consistent field naming and output formatting.
• CMS migrations: Generate portable schema blocks you can paste into templates during a redesign or platform move.

In every case, the best results come from ensuring that the structured data reflects the content on the page. If your markup claims a 5-star rating, the page should clearly show that rating and explain how it was determined.

Implementation Guide

After generating the JSON-LD, paste it into the same page that displays the review. If you are using a CMS, look for a field such as “Custom HTML”, “Header scripts”, or “Schema markup”. For static sites, you can include the script directly in your HTML template. For Laravel, WordPress, Webflow, Shopify, or any other platform, the goal is the same: ensure the JSON-LD is delivered in the initial HTML response.

If your site uses server-side rendering, generate the schema server-side so it is present on first load. If you rely on client-side rendering, confirm that crawlers can still see the JSON-LD after JavaScript executes. When in doubt, prefer server-rendered schema because it is simpler to test and tends to be more robust.

Quality checks before publishing

• Validate JSON syntax: Make sure quotation marks and commas are correct and that the output is valid JSON.
• Confirm required fields: Check that item name, author, rating value, and review body are present.
• Align with page UI: Ensure the rating shown to users matches the rating in the markup.
• Use canonical URLs: If you provide URLs, use the canonical version to avoid duplicates.
• Keep dates consistent: If you add datePublished, make sure it matches the displayed review date.

Common Mistakes to Avoid

Many schema issues come from mismatches between structured data and the content users can see. Avoid claiming aggregate ratings that are not displayed, copying ratings from another site, or using generic text that does not describe a real experience. Also avoid marking up reviews on pages that do not contain review content; schema should always be tied to visible page elements.

Another frequent mistake is mixing rating scales. If you use a 10-point scale in your UI but submit a 5-point scale in JSON-LD, that inconsistency can trigger warnings. Keep one scale, define the bounds, and use the same scale across your templates.

High-impact pitfalls

• Hidden ratings: Do not add markup for ratings users cannot see.
• Incorrect item type: Choose a reviewed item type that matches the page content.
• Spammy language: Avoid exaggerated or repetitive marketing phrases in the review body.
• Missing review count: If you claim an aggregate rating, include the review count and display it on the page.
• Inconsistent identifiers: If SKU or URL changes frequently, remove it until it is stable.

Optimization Tips

Match visible content exactly

Search engines expect structured data to represent what users can actually see. Keep the rating value, review body, author name, and review count consistent with the visible review section. If your aggregate rating is derived from multiple reviews, ensure the page clearly displays that aggregate score and the number of reviews.

Use specific, descriptive review text

A short “Great product!” can be valid, but detailed review text is more useful for users and tends to reduce quality-related warnings. Include what was tested, what worked well, and any limitations. Avoid repeating marketing copy verbatim.

Keep identifiers clean

If you include a URL, SKU, or brand name, keep them stable over time. Consistent identifiers help search engines connect structured data across crawls and reduce ambiguity between similar items.

What Review Schema Includes

At a minimum, a review markup block usually includes the reviewed item, a rating, and an author. Schema.org allows many additional properties, but the most important are those that help a crawler verify that the review is real and that it belongs to a specific item. In practice, that means providing an item name, a stable URL when possible, and a rating scale that matches your UI.

The generator focuses on the properties most commonly used on review pages: itemReviewed, reviewRating, author, reviewBody, and an optional aggregateRating. If you add optional fields such as brand, SKU, price, or availability, they should also be visible somewhere on the page (for example in a product details table) so that the structured data is not “hidden” metadata.

Common properties you may add

• image: A representative image URL for the item, typically a product photo or listing image.
• url: The canonical URL of the reviewed item or the page where the item is described.
• brand: The brand name for products, helpful for distinguishing similar items.
• sku: A merchant or internal SKU that stays stable as your catalog evolves.
• offers: Optional pricing and availability signals for product pages that display these details.
