Tool library

Free tools for static sites and small publishers.

Use these tools to review common crawl, link, sitemap, canonical, metadata, schema, and publisher-readiness issues. They are practical checks, not guarantees of indexing, ranking, advertising approval, legal compliance, or security.

Available tools

Choose the check that matches the problem.

The best user experience is to run a focused check, read the plain-English notes, and then fix the underlying page or file directly.

Schema Detector

Detect JSON-LD blocks and common schema types without pretending to replace a full rich-results validator.

How to use these tools safely

Do not submit private, internal, login-only, staging, or sensitive URLs. These tools are designed for public webpages and public publisher files. Some external servers block automated checks, so warnings should be reviewed manually before assuming a link or file is truly broken.
