Content freshness checker for AI search

AI search engines prefer fresh content, and they read dates by machine. A page with no machine-readable date has no chance in recency-weighted retrieval.

Why content freshness matters for AI search

About half of all AI-cited content is under 13 weeks old. Pages updated within 30 days earn around 3.2x more citations. Perplexity picks current-year pages at 1.69x the rate of last year's. On time-sensitive topics, a current year in the title correlates with roughly 30% more citations.

Dates only work when they agree with each other. GetSlurp checks that datePublished and dateModified exist in your markup, that the page was updated recently enough to compete, and that nothing on the page contradicts them. A 2023 copyright line in the footer undercuts a fresh dateModified in your schema.

Every check in this category

This list comes straight from the audit engine, so it always matches what the extension and MCP server actually run.

fresh.machine-datesGraded

About half of AI-cited content is under 13 weeks old; undated pages cannot compete in recency-weighted retrieval at all.

Fix: Add datePublished and dateModified to the page schema and show a matching visible date.

fresh.recencyGraded

Content under 30 days old earns ~3.2x more AI citations; Perplexity retrieves current-year pages at 1.69x the prior year.

Fix: Update the page substantively and bump dateModified; stale pages lose recency-weighted retrieval.

fresh.visible-yearGraded

A current-year signal in the title correlates with ~+30% citation rate on time-sensitive topics.

Fix: Where the topic is time-sensitive, include the current year in the title or top heading and keep it accurate.

fresh.stale-signalsGraded

Visible staleness (an old copyright year, "updated 2023") contradicts freshness signals and undermines both.

Fix: Update the footer copyright year and remove stale "updated" strings.

Content freshness checker for AI search: frequently asked questions

Does content freshness affect AI search?

Strongly. About half of AI-cited content is under 13 weeks old, and pages updated within 30 days earn around 3.2x more citations. Engines read dates by machine, so a missing date leaves you out of recency-weighted retrieval.

How do I show AI search engines my content is fresh?

Publish machine-readable datePublished and dateModified in your markup, update the page when the topic moves, and make sure nothing contradicts the date. A 2023 copyright line in the footer undercuts a fresh dateModified.

How often should I update content for AI search?

Often enough to stay current for the topic. Perplexity picks current-year pages at 1.69x the rate of last year's, and a current year in your title correlates with more citations on time-sensitive topics.
