A sitemap that hasn't been regenerated since new content was published means Google doesn't know about your newest pages through this channel — the sitemap is only useful if it's kept current, not set up once and forgotten.
A sitemap with missing or obviously fake lastmod dates tells Google it can't trust your freshness signals — reducing how often it bothers to recrawl your pages for updates.
Accurate lastmod dates within your sitemap provide search engines with genuine, useful signal about which pages have actually been recently updated, helping them prioritize recrawling of genuinely fresh content rather than expending equal crawl attention across pages regardless of whether their content has actually changed recently.
Inaccurate lastmod dates — whether stale dates that don't reflect genuine recent updates, or dates that update automatically regardless of whether meaningful content changes actually occurred — undermine the genuine value this signal is meant to provide, potentially causing search engines to either miss genuinely fresh content or waste crawl attention on pages incorrectly flagged as recently updated when no genuine change occurred.
The genuine accuracy this check requires means lastmod dates should reflect actual, meaningful content updates specifically, not automatic updates triggered by unrelated technical processes or minor, non-substantive changes — this distinction matters for maintaining the genuine usefulness of this signal rather than diluting it through overly liberal date updating that doesn't correspond to real content changes.
This represents an ongoing maintenance consideration rather than a one-time configuration — as your content management and publishing workflow evolves, periodically verifying that lastmod dates continue accurately reflecting genuine update activity ensures this signal remains a reliable, useful tool for search engines throughout your site's ongoing evolution.
The sitemap's content reflects your site's current pages, including anything published recently.
Fix it, then re-scan — the check confirms itself. No manual checkbox, the scan is the truth.
