Short answer: Yes, but only if the update is real. Changing a published date without changing the content doesn’t help, and AI models increasingly seem to weigh actual content changes over timestamp changes alone.
“Freshness” has been a loosely understood ranking factor for years, and the shortcut of just re-publishing a post with a new date is a habit worth breaking — it doesn’t hold up well for AI citation either.
What counts as a real update
New data, corrected facts, an added section answering a question the post didn’t originally cover, or updated pricing/availability information all count. A cosmetic date change doesn’t.
Old content can actively hurt you if it’s wrong
An outdated post with stale prices, closed locations, or discontinued services can get cited with wrong information — worse than not being cited at all.
Prioritize your highest-traffic pages first
A quarterly review of your top-performing pages for accuracy and completeness is more useful than a blanket republish of everything on your site.
Frequently Asked Questions
How often should I update older content?
A quarterly check of high-traffic pages, plus updates whenever a fact on the page actually changes.
Should I delete outdated posts instead of updating them?
If the topic is still relevant, updating usually beats deleting and losing the page’s existing authority.
Does changing the visible “last updated” date matter?
It’s a helpful trust signal for readers, but only when it’s accurate and tied to a real content change.
