## Definition

Content freshness is the recency of a page's content — how recently it was published or significantly updated. AI systems may use freshness as a retrieval signal to ensure users receive current and accurate information, particularly for time-sensitive or rapidly evolving topics.

## Why It Matters for AI Search

Content freshness affects AI citation in two ways. For time-sensitive queries, recently updated content is preferred over outdated content. For evergreen topics, freshness signals that a brand is actively maintaining and verifying its content — a trust signal in its own right. A content calendar that includes regular freshness updates to high-priority pages maintains citation eligibility for AI systems that factor recency into their retrieval ranking.
