Sitemap Checker
Enter a domain and we will find every sitemap it exposes — from robots.txt and the usual locations — then report each one's URL count, last update and whether it validates.

How to find the sitemap of a website
There is no single place a sitemap must live, which is why finding one takes a checker. The authoritative source is robots.txt: any line starting Sitemap: declares one. Failing that, sites conventionally use /sitemap.xml, while WordPress core uses /wp-sitemap.xml and SEO plugins often use /sitemap_index.xml. This tool checks all of them in one pass and shows you exactly what exists.
What we report for each sitemap
For every sitemap found you get its type (a URL sitemap or an index file pointing at others), how many URLs it declares, the most recent <lastmod> date — a quick freshness check — and whether it validates against the sitemap protocol, with error and warning counts. Anything that fails validation is worth running through the Sitemap Validator for line-by-line detail.
Common problems this surfaces
No Sitemap: line in robots.txt — crawlers can guess the common paths, but declaring the sitemap is free and removes the guesswork. Add Sitemap: https://yoursite.com/sitemap.xml to robots.txt.
Multiple overlapping sitemaps — a plugin sitemap and a hand-made one, half-forgotten, disagreeing about the site. Pick one source of truth and remove or redirect the rest.
Stale lastmod dates — a sitemap last touched years ago tells crawlers your site never changes, so they visit less. Regenerate it automatically on publish.
A found-but-invalid sitemap — worse than none, because tools that fetch it may discard it silently. The validation verdict here tells you immediately whether that’s happening.
Once you know what your sitemaps expose, the next question is what those pages actually say — the Answerability Check reads them and reports which visitor questions they can answer.
