AI answer corrections: three clocks, not one update time
An earlier edition of this note read two archived observations as if they timed a correction in AI answers. They do not. This is what they show, and the log that would.
A corrected fact in AI search has three separate times: when the page changed, when a crawler fetched the new page, and when an answer surface first repeated the new fact. Our archived notes show the product description of CrawlCheck wrong on 5 October and right on 29 October. That brackets one answer change. It does not show when the page or the fetch happened, or what caused the change. To measure a correction, record all three times as you go.

The page, the crawler and the answer each have their own time. These notes show an identity problem on 5 October and a correct product description on 29 October. They bracket the answer. They do not time the other two, and they do not name a cause.
Correction note. The first edition of this post, published 30 October 2026, was framed as an evidence note about how long a correction takes to reach AI answers. It was built on two archived observation notes, and by its own admission those notes established nothing about timing. This edition says only what the notes show, and turns the rest into a log a business owner can keep.
What a reader saw, and what was wrong #
The title promised a correction timeline. The evidence was two operator-written notes on the recurring question “what is CrawlCheck”: on 5 October an AI Mode answer emphasised the browser extension and mixed in a different, similarly named product; on 29 October the web product was described without that mix-up. A separate Perplexity note for a brand-discovery question had used the wrong example domain, with personalisation noted.
Those notes bracket one change in one answer. They do not timestamp when our page said the right thing, when a crawler fetched it, or which change closed the gap. The 29 October note also did not re-check the identity mix-up, so it cannot be used to say that problem is gone. Personalisation means even the answer date is one session’s date: we sampled one session each time.
The three clocks #
| Clock | What counts as a time | What our notes contained |
|---|---|---|
| Page | The deploy or edit that changed the fact | Not recorded |
| Fetch | A request by the documented crawler that received the new page | Not recorded |
| Answer | A dated, saved answer that states the new fact | Wrong on 5 October, right on 29 October, product description only |
The clocks can run out of order. An answer can pick up a fact from another source before the crawler you are watching arrives. A crawler can fetch the corrected page and the answer can keep the old fact for weeks. A record of one clock is not evidence that the others have moved.
What changed #
The post no longer presents the two notes as a measured delay. Every claim above is limited to what was recorded on those two dates. We have not run a multi-business correction study, and this note is not one.
The lesson: log all three as you go #
- Page time: write down when the corrected fact went live, from your site’s edit history.
- Fetch time: request the page yourself as the documented user agent and save what came back, so you know the new fact was being served. Verify a crawler visit by IP before treating a log line as a real fetch.
- Answer time: ask the same factual question on the same surface on a schedule, in more than one session, and save each answer with its date and citations.
- Report the interval, not a moment: if you check weekly, the change happened “between these two checks”. Keep the cases that never resolved in the record.
Published timing guidance is narrower than it looks. OpenAI’s bot documentation gives an approximate period for robots-policy changes to take effect, which is about crawl policy, not about correcting facts in answers. Google’s recrawl guidance describes uncertainty in crawling, not a promise that an AI answer will change. For what an access fix does and does not prove, see unblocking AI crawlers is not a citation result; for a larger, dated comparison of answers, see four AI models on three local businesses.

Questions this post answers
How long does it take for an AI answer to reflect a corrected business fact?
There is no single figure. A correction has three times: when the page changed, when a crawler fetched it and when an answer first repeated it. Each has to be recorded separately, and our archived notes only bracket the third for one answer.
What do the 5 October and 29 October notes show?
That an AI answer described CrawlCheck’s product wrongly on the first date and correctly on the second. They do not show when the change happened inside that window or what caused it.
Does a correct product description mean an identity mix-up is fixed?
No. The later note did not re-check the identity mix-up, so a correct description cannot be borrowed to close a separate identity error.
How should a business owner track a correction?
Write down the page time from the site’s edit history, save a fetch of the corrected page as the documented crawler, and save dated answers from more than one session. Report the window in which the answer changed, and keep the cases that never changed.
