Definition
A freshness signal is any indicator that a piece of content has been recently created or updated — including publication date, last-modified date, recent citations from other sources, and recency of the events or data referenced in the content.
Why It Matters for AI Search
AI systems weight freshness differently depending on query type. For time-sensitive topics — market data, platform features, regulatory changes — freshness is a strong citation factor. For evergreen concepts, it matters less. Keeping key pages updated with current data, dates, and references is a low-effort way to maintain citation eligibility for queries where recency matters.
