Sitemap Checker
I find pages in your sitemap that are gone, moved or missing. Google uses your sitemap as its list of pages to visit, so a clean sitemap gets new pages found sooner.
Sitemaps we found
What this checks
We read robots.txt for "Sitemap:" lines, or try /sitemap.xml. Then we open up to 100 pages from it and check that each one opens, is allowed by robots.txt, has no noindex tag, and points to itself as the main version.
