Two URLs · one bounded migration gate
URL migration safety gate
Enter an old and new URL to compare the old URL's 301/308 redirect and final destination with the new page's canonical, og:url, hreflang, robots, and sitemap. It is designed to catch “moved, but not fully updated” issues before launch.

How to read the result
- READY means this tool found the expected redirect and public references in its bounded checks.
- BLOCKED means the redirect, final URL, canonical, og:url, hreflang, robots, or sitemap needs review.
- UNKNOWN means a target could not be fetched and is never treated as PASS. Rankings, indexing, social previews, and migration completion are not guaranteed.
