Structured data checker

What structured data is, and why it is worth the effort

Structured data is a small block of code, usually written as JSON-LD, that spells out what a page is about in a way machines understand exactly. Instead of a search engine inferring that a page is about a local business, you tell it directly: here is the name, the address, the phone number, the opening hours, the reviews. Do that and you become eligible for rich results, the enhanced listings with stars, prices, FAQs and more that take up more space and earn more clicks.

It matters even more now that people ask AI assistants questions and get answers with sources. Those systems lean heavily on structured data to understand and cite a business confidently. A page with clean schema is far easier for them to quote than one they have to guess about. This tool finds the JSON-LD on any page, tells you which schema.org types it uses, and warns you when a block is broken.

The common types, and getting them right

For most small businesses the useful types are Organization or LocalBusiness for the business itself, WebSite for the site, BreadcrumbList for navigation, Product or Service for what you sell, and FAQPage for a page with real questions and answers. Each has a set of properties search engines look for. You do not need all of them, and you should never mark up something that is not genuinely on the page, because fabricated or mismatched schema can trigger a manual penalty.

The most common failure this tool catches is simple: a block that is not valid JSON. One missing comma or a stray quote and the whole block is ignored, so all the effort of adding it is wasted and you would never know. Seeing the block flagged as invalid tells you exactly where to look. The second common issue is JSON that parses but has no @type, which search engines cannot act on.

From finding problems to fixing them

This tool tells you what schema you have and whether it is valid. To confirm you are eligible for a specific rich result, run the page through Google's own Rich Results Test, linked below, which checks the required properties for each result type. If you would rather not touch code at all, adding correct structured data across a site is part of our AI SEO service. We set up Organization, LocalBusiness, Product, FAQ and breadcrumb schema properly, and get your Google Business Profile aligned with it, so search engines and AI answers describe you accurately.
