Free Schema Checker is a free web tool that scans any webpage for structured data (schema markup) and identifies missing, broken, or incomplete schema types, helping AI systems and search engines understand, trust, and cite content.
What is Free Schema Checker?
Free Schema Checker takes a webpage URL as input and returns a report of which common schema types are present, missing, or broken on that page. It runs entirely in the browser (no download required) and is built by nenawow.com, a site providing honest reviews and guides for AI tools and SEO software. The tool checks for Article schema, FAQ schema, Organization schema, and other structured data formats that AI search tools and Google look for when reading a page.
Key Features
- Free to use — No payment or subscription required; unlimited scans with no hidden charges.
- No signup required — Paste a URL and scan immediately; no account creation, email, or login needed.
- Private scanning — Results are never stored on servers; the page content is processed and discarded after the scan.
- Checks common schema types — Scans for Article, FAQ, Organization, and other structured data formats commonly used by AI systems and search engines.
- Plain-language explanations — Each missing, broken, or incomplete schema item is described in non-technical language with actionable suggestions for what to add or fix.

Who is it for?

What can you do with Free Schema Checker?
- Pre-publishing audit – Enter a draft page URL to catch missing structured data before the page goes live, reducing the risk of poor AI understanding or search engine misreading.
- Content optimization – Verify that FAQ pages include FAQ schema, articles include Article schema, and organization pages include Organization schema, adjusting markup as needed based on the tool’s feedback.
