How to check your sitemap

What the tool checks

The service loads sitemap.xml, checks the validity of the XML, support for index files, the number of URLs, the correctness of lastmod dates and the availability of the listed pages.

Typical problems: broken URLs in the map, pages with redirects, non-canonical addresses, outdated lastmod dates “in the future” and exceeding the size limits.

Recommendations

Generate the sitemap automatically so it always matches the real structure of the site. Specify the map address in robots.txt and add it to Yandex Webmaster and Google Search Console.

For online stores it is convenient to split the map by page type (categories, products, articles) — this makes it easier to track indexing of each section.

Frequently asked questions

Why do you need sitemap.xml?+

A sitemap helps search-engine crawlers find all important pages, especially new and deeply nested ones. For large sites and sites with poor internal linking, a sitemap speeds up indexing.

How many URLs can one sitemap hold?+

Up to 50,000 URLs and up to 50 MB uncompressed. If there are more pages, use a sitemap index file that references several maps.

Are lastmod, changefreq and priority required?+

Only loc is required. Google takes lastmod into account if it is reliable, and ignores changefreq and priority. Yandex also relies mainly on lastmod.

What if blocked pages ended up in the sitemap?+

Remove them: a sitemap should contain only canonical, indexable pages that return a 200 status. Contradictions between the sitemap and robots.txt/noindex are a negative signal for search engines.
