Freshness Signals
Freshness signals are indicators that content is current — recent dates, updated pricing, current competitor names, recent statistics. AI engines weight fresh content more heavily than stale content for time-sensitive queries.
What it is
Freshness is one of the strongest signals AI engines use to rank citations. A page with a 2026 modified date, current pricing, current product names, and recent statistics will outrank an older page with stale information for the same query — even if the older page has more authority. Practical freshness signals: explicit lastModified dates in schema, year references in titles ('2026'), updated pricing tables, references to current competitor products, current statistics with cited sources.
Why it matters for GEO
Stale pages are cited less often. Updating cornerstone content quarterly is one of the highest-ROI maintenance tasks in GEO.
The CiterLabs perspective
CiterLabs sprints include a freshness audit on top 30 cornerstone pages.
