One URL · four bounded checks
Public URL publishing gate
Enter one public URL to check meta and OGP, robots and sitemap, HTML accessibility, and HTTP security headers before sharing. The result becomes a local repair report.
Four GET requests run in sequence. Each uses the existing 2 MiB, 10-second, redirect, and no-credentials safety boundary.

How to read it
- FAIL means a mechanical finding was detected. NOTICE means you should review an item.
- UNKNOWN means a source could not be fetched; it is never treated as PASS.
- This is an assistive pre-publish check. It does not guarantee rankings, social crawls, WCAG conformance, or security.
