Tracking a brand in ChatGPT is mostly a sampling problem. Because its volatility is moderate, answers to the same prompt drift week to week as the underlying index refreshes, a single check tells you very little. ChatGPT answers from model weights first and reaches for the web when the question looks fresh, local or specific. Its search index is Bing-derived, so a page Bing has never indexed is effectively invisible to it no matter how well it ranks in Google.
How ChatGPT actually decides
ChatGPT answers from model weights first and reaches for the web when the question looks fresh, local or specific. Its search index is Bing-derived, so a page Bing has never indexed is effectively invisible to it no matter how well it ranks in Google.
Its citations skew toward encyclopedic and reference sources: published analyses put Wikipedia at roughly 47.9% of its top citations. In practice that means the surfaces worth auditing first are Wikipedia, established news and reference sites, vendor documentation, G2 and review aggregators.
The method, in order
Fix your prompt set before you measure anything. The same question asked two ways gets two answers, so the prompts have to stay constant or the trend is meaningless.
Decide what counts as a hit. Being named in the answer and being cited as a source are different outcomes, and ChatGPT often names brands without linking them, so the two have to be recorded separately.
Match the cadence to the engine. ChatGPT changes moderate, so a daily check still beats weekly, because it separates a genuine change from a single odd answer.
Record the competitors named in your place. The brands that appear instead of you are the most actionable output of any AI-visibility check.
Tie it back to search. A visibility score with no traffic behind it cannot justify itself: Search Console is what turns it into a business number.
The honest caveat
It is the slowest of the six to notice a new page, because a Bing-derived index has to find you first. Sites that only ever submitted a Google sitemap routinely discover they are absent here.
Cituna checks ChatGPT daily alongside the other five engines, ChatGPT, Perplexity, Gemini, Claude, Grok and Google AI Overviews, on the $39 Starter, and pairs the result with Google Search Console so a change here can be tied to real clicks. We do not track Microsoft Copilot.
