What freshness signals does the checker inspect?

It checks JSON-LD datePublished and dateModified, Open Graph article dates, HTML time elements, Last-Modified, ETag, Cache-Control, and Age headers when those signals are publicly exposed.

Does a recent Last-Modified header prove the article was updated?

No. Last-Modified is a transport and cache signal and can change because of deployment or template behavior. Editorial dates in structured data and visible markup provide different evidence and should be kept consistent.

Does a high signal-quality score improve rankings or AI citations?

No guarantee is implied. The score only measures whether date evidence is present and internally consistent. Content quality, source authority, crawl behavior, relevance, and many other factors remain separate.

Why can the checker fail on a public page?

The site may block automated requests, require JavaScript or authentication, return non-HTML content, exceed the response-size limit, redirect too many times, or time out. Private network addresses are intentionally blocked.

Tool 01

AI Content Freshness Checker

Inspect a public page for publication, modification, cache, and conflicting freshness evidence.

Check a public webpage

We fetch only public HTML and response headers. No cookies, login data, or page content is stored by this interface.

Page URL

The checker is rate-limited and accepts public HTTP/HTTPS pages only.

Editorial dates

Checks JSON-LD, article metadata, and machine-readable time elements.

HTTP evidence

Reports Last-Modified, ETag, Cache-Control, and Age when exposed.

Signal conflicts

Flags date disagreement instead of treating the newest timestamp as truth.

Content evidence audit

Make publication and update signals consistent and defensible

A page can expose several dates that describe different events. Editorial metadata, visible dates, deployment headers, and cache validators should not be collapsed into one unsupported claim that the content is fresh.

Understand each date source

datePublished and dateModified in relevant structured data are explicit editorial claims. An HTML time element makes a date visible and machine-readable. Article Open Graph properties provide another publishing signal. Last-Modified and ETag primarily support HTTP validation and may change because a template or deployment changed rather than because the article was substantively revised.

The checker reports these sources separately and flags broad disagreement. It does not inspect editorial history, determine whether a rewrite was meaningful, or claim that a newer date improves ranking. Those conclusions require evidence beyond public markup.

Use valid ISO dates in structured data.
Show the same relevant date to readers with a time element.
Update dateModified only after meaningful editorial changes.
Keep template deployments from rewriting article dates automatically.

Create a repeatable refresh process

Review pages when facts, product capabilities, pricing, regulations, screenshots, or cited sources change. Keep a short change log internally, revise the content, verify links and claims, then update the editorial date signals together. Re-run this checker after publishing to confirm the public response is consistent.

Freshness is not a substitute for usefulness. A recent timestamp on unchanged copy is weaker than a properly maintained page with clear sourcing, direct answers, and accurate structured data.
