Mydentify Sitemap Checker Review 2026

Mydentify's Sitemap Checker is a free XML sitemap validator with one convenience most competitors skip: give it just a website URL and it discovers the sitemap itself, first from robots.txt and then from the conventional /sitemap.xml path, telling you which route worked — itself a useful signal, since a sitemap that is not declared in robots.txt is easy for crawlers to miss. Point it at a sitemap URL directly and it validates that instead. The checks target the things that silently break indexing: malformed XML structure, relative instead of absolute URLs, duplicate location entries, invalid lastmod values, and the sitemap protocol's 50,000-URL and 50 MB per-file limits. Sitemap index files are handled with bounded sampling of up to three child files. Rather than a bare pass/fail, the report returns the actual parsed entry list with each URL and its lastmod, so you can eyeball what your site really declares to search engines — often the fastest way to spot a stale generator or a staging URL that leaked into production. Plain-text output is available for machine reading, and results stay private. It is free with no account, and honest about scope: it validates the sitemap document, not the URLs inside it — there is no per-URL status checking, no crawl, and the tool explicitly does not guarantee crawling or indexing. There is no bulk mode, scheduling or history either, so regression tracking across deploys stays manual. Like the rest of Mydentify's free tool set it is a lead magnet for the parent directory platform, but a well-built one: discovery, parsing and validation all genuinely work, and it costs nothing to make sitemap checks part of every deploy checklist.
