Why this signal matters for Google
For Google, content that ages without revision loses trustworthiness. On many topics, technology, health, finance, regulation, information moves fast, and a frozen page signals abandonment at best, an error at worst. That is the Query Deserves Freshness principle: some queries explicitly call for recency.
Conversely, a page that is regularly updated and visibly dated sends two complementary messages: the information is current, and a competent human is taking care of it. That is exactly what Google's Quality Raters are trained to recognize, staleness destroys perceived expertise, freshness reinforces it.
The Mq signal works on two levels. Algorithm side: higher crawl frequency, better eligibility for freshness-sensitive queries, consistency between the declared date and the actually detected change. Human side: a recent "Updated on" lifts SERP CTR and reader trust before the first line is even read.
It is also the best-ratio signal on the board: high impact, easy effort. No new content production, no rare skill, just editorial discipline. Freshness is not decreed by a date: it is proven by substantial, dated, traceable changes.
The NeuroEEAT scoring grid (0-10)
Use this scale to self-assess your strategic pages. Aim for a minimum of 7/10 on YMYL content and commercial pages.
| Score | Description | Concrete indicators |
|---|---|---|
| 0–2 | Abandoned content | No visible date, outdated figures and screenshots, dead or obsolete sources |
| 3–4 | Cosmetic freshness | Publication date only, or date changed with no detectable substantive change |
| 5–6 | Occasional revision | Visible "Updated on", some real edits, but no regular cycle |
| 7–8 | Established revision cycle | Revision calendar followed, visible changelog, sources refreshed at each pass |
| 9–10 | Exemplary freshness | Substantial dated and archived revisions, public changelog, sources < 12 months, data updated ahead of competitors |
How to audit it on your site
Auditing the Mq signal takes 5 steps. Start with your 10 highest-traffic pages and your commercial pages.
- 01
Inventory the displayed dates
Does every strategic page display a last-revision date distinct from the publication date? Without a visible date, the signal is inactive.
- 02
Cross-check declared date vs. actual change
Compare the displayed date with the last substantial change (CMS history, Wayback Machine). A systematic gap = manipulation signal.
- 03
Hunt perishable elements
Figures, prices, screenshots, tool names, year mentions ("in 2024"): list everything that dates the page against you.
- 04
Check source freshness
References older than 18 months on a fast-moving topic weaken the whole page. Check for dead links too.
- 05
Score and plan
Assign a 0-10 score per page, then rank by traffic × staleness. High-traffic, low-score pages form your priority revision queue.
How to activate or improve it
Three activation levels depending on your current editorial discipline.
Date and minimal ritual
- Display "Updated on [date]" at the top of the article
- Distinguish publication date from revision date
- Fix figures and dead links as you go
- Update the existing URL, never a new one
- Start with the 10 highest-traffic pages
Structured revision cycle
- Quarterly calendar for strategic pages
- Visible mini-changelog ("Added 2026 figures…")
- Replace sources older than 12-18 months
- Refresh screenshots and examples
- Mark dateModified in the Article schema
Industrialized freshness
- Revision queue driven by traffic × staleness
- Public archived changelog (browsable versions)
- Automatic alerts on perishable data
- Systematic review after every Core Update
- Publish updates before competitors (sector data)
5 common mistakes to avoid
Sector specifics
Near-mandatory freshness
Regulations, dosages, rates: outdated information can concretely harm the user. Revision cycle of 3 to 6 months maximum, with review by the signing expert.
The product moves faster than the docs
Screenshots, pricing, feature names: everything expires within months. Sync content revision with product releases.
Prices and availability, continuously
Product pages and comparisons must reflect real prices and stock. A comparison with wrong prices destroys trust and conversion rate simultaneously.
Revise without distorting
Even timeless content deserves an annual pass: refreshed examples, recent sources, verified links. The revision date reassures without a full rewrite.

FAQ
How often should you update?
It depends on the topic: YMYL or technology content deserves a revision every 3 to 6 months; more timeless content, at every real evolution of the subject, with at least an annual control pass.
Is changing only the date enough?
No. Google compares the displayed date with the actual scope of detected changes. Without substantial change, the effect is null or negative: it is a manipulation signal.
Should you create a new URL for a major overhaul?
No: update the existing URL to keep its history, signals and backlinks. A new URL starts from zero and splits your authority.
Should the revision date appear in the Schema?
Yes: fill in dateModified (in addition to datePublished) in your Article markup. Google cross-checks this value against the visible date and the actually detected change, all three must match.
Does updating really improve rankings?
On freshness-sensitive queries, yes, often within weeks. On others, the effect is cumulative: better crawl frequency, higher CTR thanks to the recent date in the SERP, and increased perceived reliability.
