Paste your sitemap.xml URL. We'll check its format, size and every URL and lastmod date for problems.

What it does

Check your XML sitemap's format, size, status codes and lastmod dates, so search engines get an accurate list of the pages you want indexed.

    Valid XML

    Whether the file parses as a sitemap or sitemap index.

  2. 02

    Size limits

    Under 50,000 URLs and 50 MB per file.

  3. 03

    A sample of listed URLs checked for errors and redirects.

  4. 04

    lastmod dates

    Whether dates are present, valid and believable.

    We fetch and parse the file, then check the URLs inside.

Reading your results

Good

Clean sitemap

Valid XML listing only live, indexable pages with accurate dates.

Check

Redirected URLs listed

List the final URLs instead, so search engines don't waste time following redirects.

Fix

Errors or invalid XML

Broken files or 404s in the sitemap undermine search engines' trust in it.

Why it matters

A sitemap tells search engines which pages matter. If it's full of redirects, errors or pages you've blocked, they learn to trust it less. A clean sitemap helps new and updated pages get discovered faster.

Questions

About the sitemap validator.

Most sites benefit from one, especially large sites, new sites and sites with pages that aren't well linked internally.
