Freshness signal
The cues that tell a retrieval system how current your content is, including visible dates, structured data timestamps and substantive updates.
In depth
What it really means
Retrieval systems favor recent content on anything time-sensitive, and they need evidence of recency. A page with no visible date, no dateModified in schema and no year in the copy looks undated, and undated loses to dated on any query where currency matters.
The distinction that actually matters is real updates versus fake ones. Changing a date stamp without changing the content is detectable and increasingly discounted. Substantive revision, with the date reflecting it, is what works.
How it works
- Crawlers record when content changed and by how much.
- Schema dateModified and visible dates are read as claims about recency.
- The system estimates whether the query has a freshness requirement.
- For queries that do, recent and substantively updated content is favored.
Pros & cons
Pros
- Updating existing pages is cheaper and faster than publishing new ones.
- Dated, current content is preferred by reasoning models evaluating reliability.
- It gives your best pages a repeatable maintenance path.
Cons
- Freshness needs ongoing work, so content becomes a running cost.
- Date-only changes with no substance can hurt rather than help.
- Evergreen content gets little benefit, so the effort is wasted there.
Common mistakes
- Bumping the modified date with no real change to the content.
- Hiding the publication date entirely, which reads as undated rather than timeless.
- Leaving year references like ‘in 2024’ inside content you claim is current.
- Updating everything on a schedule instead of the pages where currency matters.
Best practices
- Show a visible last-updated date and back it with dateModified in schema.
- Only change the date when you have changed something meaningful.
- Refresh the statistics, examples and product details, not just the wording.
- Add a short changelog note saying what was updated.
- Prioritize pages where the answer genuinely goes stale: pricing, tools, comparisons, benchmarks.
FAQs
What is a freshness signal?
Any cue telling a retrieval system how current your content is: a visible date, a dateModified timestamp in schema, or evidence of substantive revision.
Does updating the date improve rankings?
Not on its own. Date changes without content changes are detectable and get discounted. Substantive updates with an accurate date are what work.
Should I remove dates from evergreen content?
No. Undated content looks unverifiable rather than timeless. Show the date and keep the content genuinely current.
Which pages should I refresh?
The ones where the answer goes stale: pricing, tool comparisons, statistics, benchmarks and anything with a year in the title.
