Canonical + Sitemap Consistency Checker
Enter a URL to compare it against its final redirected URL, canonical tag, and sitemap listing.
About this tool
This flags obvious mismatches between what you requested, what the site actually served, and what it declares as canonical — useful for catching duplicate-content or migration issues. Sitemap comparison requires a reachable, standard sitemap to check against.
Frequently Asked Questions
- What does this tool compare?
- The URL you requested, the final URL after redirects, its canonical tag, and whether it's listed in the sitemap.
- What does a mismatch usually mean?
- Often a sign of a migration issue, duplicate content, or an outdated sitemap — worth reviewing, not an automatic error.
- Does sitemap comparison always work?
- It requires a reachable, standard sitemap to compare against; if none is found, that's noted.
