Its own index and the OAI-SearchBot crawler
ChatGPT search draws on OpenAI's own index, built by the OAI-SearchBot crawler. A site that blocks this bot in robots.txt cannot be surfaced or cited in ChatGPT search results.
Per-provider visibility
ChatGPT visibility: how to get recommended.
There is no ranking inside ChatGPT. There is an answer your company is in or absent from. EntityRise measures this on 20 approved buyer questions, separately for each of five providers, and shows what to fix so the answer includes you.
How ChatGPT builds an answer
What decides the result
ChatGPT combines model knowledge with live search and cites the sources an answer leans on. Its share of AI referral traffic is the largest, at 74.8% (Similarweb, 2026), so the ChatGPT result carries the most weight.
Sources and weights
How ChatGPT differs from the rest
Licensed publisher content
OpenAI holds licensing deals with publishers including Associated Press, Axel Springer, the Financial Times, News Corp and Reuters. Brand presence in media that feed ChatGPT directly counts for more here than elsewhere.
Two layers: model memory and search
With search off, ChatGPT answers from training memory, where what has been widely and consistently repeated about a company over years is what counts. The slowest layer of visibility to build, and the most durable.
What this changes about your sources: do not block OAI-SearchBot, pursue mentions in major media, and build one identical definition of the company everywhere, because that is what settles into model memory.

Measurement
How we measure ChatGPT visibility
01A column in the matrix
In the report ChatGPT has its own column in the response matrix and its own index row: mentions, active recommendations, prominence and citation support computed from its answers alone.
02Same questions, separate result
Each of the 20 questions goes to ChatGPT independently; the result is never averaged with other providers.
03Six signals per observation
Mention, active recommendation, alternative, position, citation support and description accuracy.
04The model version in the report
The exact model version used in your audit is recorded in Audit Integrity.
Common questions
Straight answers.
How do I check whether ChatGPT recommends me?
Ask the questions your buyer would ask, without your company name, and record the answers. The audit does the same in a controlled way: 20 approved questions, a sealed set and a repeatable result.
Can you buy a presence in ChatGPT?
No. No provider sells placements in answers. The result is earned openly: a clear company description, content for buyer questions and evidence a model can cite.
Does the ChatGPT result carry over to other providers?
Partly. The same work raises the odds everywhere, but each provider weighs sources differently, which is why the audit measures each one separately instead of showing one average.

The $49 audit shows ChatGPT answers to 20 of your buyer questions, next to the four other providers.
