What is the XML sitemaps protocol?

It is an open industry standard supported by all major search engines that defines the XML structure for submitting URL lists and update timestamps.

Does Google still use priority and changefreq tags in sitemaps?

Google representatives have stated that Googlebot largely ignores `` and `` tags, focusing primarily on `` and accurate `` timestamps.

What date format should be used for lastmod in XML sitemaps?

Use the W3C / ISO 8601 date format, such as `YYYY-MM-DD` (e.g., `2026-09-05`) or full timestamp `YYYY-MM-DDThh:mm:ss+00:00`.

What is the maximum file size for an XML sitemap?

The maximum file size for an uncompressed XML sitemap is 50 MB, or 50,000 URLs. Sitemaps can also be compressed using gzip (`sitemap.xml.gz`) to save bandwidth.

Can an XML sitemap contain URLs from multiple subdomains?

No. A sitemap can only contain URLs from the same domain and subdomain where the sitemap file is hosted, unless domain-level ownership is verified in Search Console.

How do I submit an XML sitemap to Google Search Console?

Log into Google Search Console, navigate to Sitemaps in the left menu, enter your sitemap URL (e.g. `sitemap.xml`), and click Submit.

Does submitting a sitemap guarantee that all my URLs will be indexed?

No. Sitemaps assist search crawlers in discovering URLs, but indexing depends on content quality, uniqueness, site authority, and internal linking.
