In shortFreshness is the match between a page and reality, not its age. Definitions decay slowly, market claims fast, how-tos with their tools — set review cadence by decay rate and fix the staleness signals anyone can see.

Content freshness, for AI visibility purposes, is the degree to which a page still describes the world it claims to describe — which is not the same thing as its age. A definition written five years ago can be perfectly current; a market overview written last quarter can already be wrong. So the question "how fresh does content need to be" has no single answer, but it has a usable one: fresh enough that nothing on the page signals a world that no longer exists, checked on a schedule set by how fast the page's subject decays rather than by the calendar. That is what this piece works out. Two adjacent problems are covered elsewhere: if you already know a page is stale and want to update it without losing the citations it has earned, the mechanics live in How to refresh old content without losing AI citations; if an assistant is repeating wrong facts about your company, that is a correction problem, not a freshness problem — see What to do when AI cites outdated information about you.

Freshness is not age

Two pages published the same week can decay at completely different rates, because what decays is not the page — it is the match between the page and reality. Age is invisible to a reader; staleness is legible. A page betrays its staleness through signals anyone can check: an "as of 2023" under a claim presented as evergreen, screenshots of a product interface two redesigns old, examples built on companies that have since folded or renamed, links that resolve to nothing. A reader who hits one of those signals tends to discount the whole page, and the text assistants ingest is the same text the reader saw. We can observe which pages carry these signals and which do not; we cannot observe how any given engine weighs them internally, and the honest position is to fix what is legible rather than theorize about what is weighted.

This cuts the other way too. A page with no stale signals does not need updating merely because its publication date is old. Rewriting a still-correct definition to look busy is churn, and churn has real costs — the refresh guide linked above exists because careless updates can lose the citations careful ones keep.

A decay schedule by content type

Definitions and concept explainers age slowly. A piece defining a term decays only when the field's language shifts — the concept gets renamed, absorbed, or split. These pages can stay correct for years, and their accumulated history of being cited is worth protecting.

Market claims age fast. Any sentence with a count, a size, a ranking, or a "currently" in it starts expiring the day it is published. Landscape overviews, vendor lists, and "state of the market" pieces are the highest-maintenance content you can own, and a stale one is worse than none, because it confidently describes a market that has moved.

How-tos and integration guides age with the tools they describe, not with time. A setup guide is current until the interface, the API, or the pricing model it walks through changes — which can be next month or not for years. Their decay is event-driven, so their review trigger should be event-driven too: watch the tools, not the calendar.

Positioning and opinion pieces age with your strategy. They are stale the day you no longer believe them, whatever the datestamp says.

Announcements are the special case: they are correctly frozen. A launch post or a release records a moment in time, and its usefulness comes from staying exactly as issued — the same property that keeps the format useful, as Do press releases still matter argues. Updating an announcement destroys the one thing it is for.

What engines appear to prefer

"Appear" is the honest verb. Observed behaviour suggests assistants often lean toward recent-looking sources for time-sensitive questions, and answer sets demonstrably shift over time — How often do AI answers change looks at that churn directly. But recency preference is engine behaviour, and engine behaviour changes without notice: how strongly any engine favors fresh material this quarter says little about next quarter, and different engines visibly differ from each other today. Building your maintenance policy on a specific engine's current appetite is building on sand.

What you control is the evidence you present: visible dates, a last-reviewed line that tells the truth, and substance that matches the datestamp. The tempting shortcut — bumping the date without touching the content — is legible to any reader who compares the date against a dead example three paragraphs down, and it spends trust you will want later. If recency signals matter to engines, an honest date serves them; if they stop mattering, an honest date still serves your reader.

The staleness audit anyone can run

Because staleness is legible, checking for it needs no judgment calls. Sweep for: years in titles or claims that have passed; examples naming products, companies, or features that changed; screenshots of superseded interfaces; terminology your field has moved past; links that 404 or redirect somewhere unintended; and numbers presented as current that no longer are. Every hit is either fixable in minutes or evidence the page needs the full refresh treatment. This audit is mechanical enough to delegate, which is exactly why it tends not to get done — nobody owns it. Assign it.

Matching cadence to decay

Put the pieces together and the maintenance policy writes itself: inventory pages by type, assign each type a review rhythm that matches its decay — frequent for market claims, event-triggered for how-tos, sparse for definitions, never for announcements — and treat review as distinct from rewrite, since most reviews should end with "still correct" or a two-line touch-up. Then close the loop: a refresh is a hypothesis that the page will serve answers better, and How to measure whether content changed AI answers covers testing it. Teams use Magrios to watch answer drift on the questions each page targets, which turns freshness work from a guess into a queue ordered by evidence. The standard, restated: fresh enough means no legible signal contradicts the present, and the date on the page is one you would defend.

Frequently asked questions

Does content age hurt AI visibility?

Age alone is invisible; legible staleness is the problem. A page with dead examples, superseded terminology, or dates contradicting its claims gives readers and engines reasons to discount it. A still-correct old page needs no rewrite, and churning it risks the citations it has earned.

How often should I update articles?

By decay rate, not by calendar. Market claims need frequent review, how-tos need review when the tools they describe change, definitions rarely, and announcements never. Most reviews should end with 'still correct' or a small touch-up rather than a rewrite.

Do AI engines prefer recent content?

Observed behaviour suggests assistants often lean toward recent-looking sources for time-sensitive questions, but recency weighting is engine behaviour and changes without notice. Keep dates honest and substance current; bumping a datestamp without updating content is legible and spends trust.

Should I update the publication date when I refresh a page?

Only when the substance genuinely changed. An honest last-reviewed line serves readers and engines either way; a bumped date over unchanged content is easy to catch against stale examples in the text.
