Summary

Claim: Ahrefs (Despina Gavoyannis), 16.975M citations across 7 AI platforms: *"The average age of URLs cited by AI assistants is 1,064 days, compared to 1,432 days for URLs in organic SERPs — 25.7% 'fresher'… ChatGPT is most likely to cite newer pages."*

Source: https://ahrefs.com/blog/fresh-content/ — 2026.

Confidence: Verified (primary measurement on a large sample).

Caveat: Ahrefs sells SEO tools, but this is a direct measurement on its own crawl — vendor source, large-N primary data.

Why this matters for Candid: The single best freshness datapoint in the literature. Large-N, multi-platform, directly comparable to organic SERP age. Anchors R4 — Keep frequently-updated content fresh SUBSTANTIVELY, not cosmetically; cadence at least every 60–90 days for the pages that matter and supports Capability 3 — live or frequently-updated data: content whose value depends on currency (availability, pricing, status, hours, inventory) refreshed on a cadence rather than written once.
