Google Sitemaps Docs Updated: Lastmod Date Should Be Last Significant Update

Google Stamps Paper

Google has made a small note to the sitemap documentation to add that the lastmod date specified in the sitemap file "should reflect the date and time of the last significant update to the page." This change was made after I covered the topic of Google trusting or not trusting that lastmod field in your sitemap file.

Gagan Ghotra spotted this update and posted on X about it. He said, "Google added a note about lastmode in Search Central document about sitemaps." He is right.

When you compare the old version to the current version - you can see this document was updated on June 21, 2024.

Google added this section:

The lastmod value should reflect the date and time of the last significant update to the page. For example, an update to the main content, the structured data, or links on the page is generally considered significant, however an update to the copyright date is not.

Google also made one small additional tweak to the text sitemap section, just to clarify it. Here is what was added in blue:
