Practical Lens 23: Dates are recency signals
AI crawlers use timestamps to judge freshness and stability. If key identity pages have no dates (or stale ones), outputs often hedge or pull from other sources.
What this lens means
Dates are a machine-verifiable freshness signal. If your reference pages don’t expose recent updates (or expose stale dates), AI crawlers reduce certainty and may source “what you do” from elsewhere.
Why this happens
- AI crawlers use timestamps to estimate whether identity claims are current or outdated.
- When pages lack dates, crawlers rely on weaker freshness proxies (crawl time, external references, cached copies).
- Stale or inconsistent dates across reference pages create uncertainty and hedging.
What this usually indicates
- No timestamps: key reference pages have no visible or structured update dates.
- Stale dates: pages show old dates despite changed offer/naming.
- Inconsistent dates: different reference pages imply different “current” versions.
- External recency: AI cites third-party sources because they look fresher than first-party pages.
What to verify (evidence-only)
- Do reference pages expose clear last-updated signals (visible date and/or structured signals)?
- Are dates consistent across homepage/about/services when the offer changes?
- Do language variants update in sync (no outdated claims in one variant)?
- Does sitemap.xml lastmod reflect real updates for reference pages?
- Do AI outputs align with your latest wording after updates, across multiple tools?
Frequently Asked Questions
Do AI crawlers trust dates on pages?
They treat dates as one recency signal among others. Consistent timestamps across reference pages increase confidence that identity claims are current.
Where should dates appear?
On identity-critical pages (about/services) and in structured signals like sitemap.xml lastmod where applicable. Avoid misleading stale dates.
Why does AI keep using old wording?
Often because first-party reference pages don't broadcast recency clearly, so crawlers lean on older cached content or third-party sources.
