Content Freshness Signal
Content freshness signals are indicators that communicate to search engines and AI systems how recently content was created or updated. In AI search, freshness is a strong retrieval signal — content that has been updated within the past 60 days is approximately 1.9 times more likely to be included in AI-generated responses than older, stale content.
Types of Freshness Signals
Freshness signals include: the dateModified and datePublished values in Article schema markup, the Last-Modified HTTP header, visible publication and update dates on the page, and the recency of the content's indexing by search engines.
Freshness as a GEO Tactic
For GEO, maintaining content freshness is one of the highest-leverage tactics available. This doesn't mean publishing new content constantly — it means regularly reviewing and updating existing content with current data, new examples, and refreshed sections.
A Practical Approach
A practical approach is to create a content refresh calendar: audit your top-performing pages monthly, update statistics quarterly, and add new sections or expand coverage when new developments arise in your space.
