Frequently asked questions

What is the maximum size of a sitemap?

A single sitemap may hold up to 50,000 URLs and 50 MB uncompressed. Larger sites should split into several files and list them in a sitemap index.

Which tags are required in a sitemap?

Each URL entry needs a loc tag with a full address. The lastmod, changefreq and priority tags are optional, though a correct lastmod date can help.

Why are duplicate URLs flagged?

Listing the same address twice wastes crawling and suggests the sitemap is out of date. Keep each page once, and use the preferred version of the URL.
