WordPress 6.5 Delivers Powerful SEO Advantage with Lastmod Support

Get ready for a significant boost in your website’s SEO performance! WordPress 6.5 introduces a groundbreaking feature – native last mod support within sitemaps. This seemingly simple addition can revolutionize how search engines crawl and index your content, leading to increased website visibility and organic traffic.

What is Lastmod and Why Does it Matter?

Lastmod stands for “last modified.” It’s a metadata tag in your sitemap that tells search engines the last time a specific webpage on your website was significantly updated. Search engines like Google and Bing use this information to prioritize and schedule their crawls.

Think of it this way: Search engine crawlers are constantly delivering information (indexing websites) just like a delivery person brings packages. With last mod, it’s like having a “recently delivered” section on your doorstep. The delivery person can prioritize dropping off these new packages first, ensuring your latest content gets indexed quickly.

Currently, only 21% of WordPress websites utilize version 6.5, which offers native lastmod support. Upgrading to this version or exploring alternative solutions for other platforms can significantly improve crawl efficiency for search engines.

The WordPress Developer Community Delivers

The credit for this innovative feature goes to the dedicated WordPress developer community, spearheaded by the remarkable Pascal Birchler. Their tireless efforts have resulted in a seamless integration of last-mod support within WordPress 6.5.

This means:  As a WordPress user running version 6.5 or above, you no longer need to manually configure lastmod tags. WordPress automatically populates this field in your sitemaps, saving you valuable time and ensuring accuracy.


42Works build beautiful, user-friendly, and SEO-friendly custom WordPress websites from the ground up, ensuring optimal lastmod integration and adherence to best practices.

A Call to Action from Google’s Gary Illyes and Bing’s Fabrice Canel

Both Google and Bing representatives have enthusiastically endorsed the last mod implementation in WordPress 6.5. Gary Illyes from Google strongly encourages website owners to upgrade, stating:

“If you’re on WordPress, since version 6.5, you have this field natively populated for you thanks to Pascal Birchler and the WordPress developer community… If you’re holding back on upgrading your WordPress installation, please bite the bullet and just do it (maybe once there are no plugin conflicts).”

Fabrice Canel from Bing echoes this sentiment, highlighting the importance of the last mod for search engines – regardless of their underlying technology (AI-driven or rules-based). He recommends using lastmod in conjunction with IndexNow for a comprehensive and fresh SEO strategy.
