CORPUSTool page
Schema checker for business websites.
Run a free audit to see whether your site has Organization, LocalBusiness, Article, Product, or FAQ structured data that machines can read.
No account or email needed for the first report. Pro is $99/mo for weekly monitoring and up to 10 sites.
Why schema matters
Search engines and AI systems need clear business facts. The audit checks JSON-LD, titles, contact signals, and whether the content around those facts is readable.
What the report shows
The report marks missing or thin structured data next to the other SEO, trust, content, speed, and AI-citability findings, so schema work is prioritized against the full site.
What Pro adds
Pro generates JSON-LD snippets tied to the findings and keeps a weekly audit history for up to five sites.
