Sitemap Missing Lastmod Dates
What This Means
The sitemap URLs do not include lastmod (last modification) dates. While optional, lastmod helps search engines prioritize crawling of recently updated content.
What Triggers This Issue
This issue is triggered when sitemap URL entries do not include the optional <lastmod> element indicating when the page was last modified.
How To Fix
Add accurate lastmod dates to your sitemap entries. Only update the lastmod when the page content actually changes significantly. Inaccurate or constantly changing lastmod dates may be ignored by search engines.
