There are two timelines, not one. Changes that depend on live search can show up in a ChatGPT answer within days, once your pages are reachable and indexed. Changes that depend on the model's own built in picture of your business move much slower, typically over three to six months. That second figure is this site's own estimate, based on how the two routes work, not a number OpenAI has published.
Why placement can never be guaranteed
Before either timeline matters, there is a harder fact underneath both of them. OpenAI states plainly that ChatGPT ranks search results using multiple factors intended to help users find relevant, reliable information, and that placement is not guaranteed. No provider, including this one, controls what a model decides to say. Anyone selling a guaranteed date or a guaranteed position is describing something outside their control as if it were a service they deliver.
What has to be true first
Neither timeline starts from zero. A few things need to already be in place:
- Crawler access. OAI-SearchBot needs to be allowed to crawl your site, and your host or CDN needs to allow traffic from OpenAI's published searchbot IP addresses. Without this, the live search route cannot see your page at all.
- Pages that actually load. A page that times out, blocks the crawler with a firewall rule, or sits behind a login is invisible regardless of how good the content is.
- Consistent details. The same name, address, phone number and core facts across your own site and the places that mention you, so there is one version of the truth to find.
What tends to slow things down
The following is reasoning about how the two routes work, not a quoted OpenAI statement. A blocked crawler stops the live route outright. Inconsistent listings, different addresses or phone numbers in different places, give both routes conflicting information to reconcile. Thin pages that state almost nothing in plain text give a search system little to cite and give the training route little to learn from. None of these guarantee a bad outcome, but each one adds friction to a process that already has no guaranteed outcome.

How to measure progress instead of guessing
Since there is no dashboard that reports "ChatGPT recommendation progress," the only honest method is to ask the same buyer questions on a fixed schedule, monthly works well, and keep the dated transcripts. See how to check what ChatGPT, Perplexity, Gemini and Google AI say about your business for the exact method. A change in what comes back over a few cycles is the only real signal available.
A red flag worth knowing
If a provider quotes you a guaranteed date or a guaranteed position in an AI answer, that is the clearest sign to walk away, for the reason above: nobody controls what a model outputs. See how much AEO actually costs in 2026 for the fuller list of red flags and what a fair engagement looks like instead.
Frequently asked questions
Why are there two different timelines?
Live search can reflect a page change within days, because the assistant reads the page again each time it searches. The model's built in picture of a business moves more slowly, typically over three to six months, because it depends on new references accumulating across the web. This is the site's own estimate based on how the two routes work, not a published statistic.
Can anyone guarantee when ChatGPT will start recommending my business?
No. OpenAI states directly that placement is not guaranteed. Any provider promising a specific date or position is not describing something within their control.
What has to be true before either timeline can start?
OAI-SearchBot needs to be allowed to crawl the site, the host or CDN needs to allow OpenAI's published searchbot IP addresses, and the business details on the page need to be consistent. None of that guarantees a result, but none of the above can happen without it.
How do I know if progress is actually happening?
Ask the same buyer questions on a fixed schedule, such as monthly, and keep the dated transcripts. A change in what comes back is the only real signal, since there is no dashboard that reports ChatGPT recommendation progress directly.
