AI Visibility Audit: What ChatGPT Says About You
An AI visibility audit shows how ChatGPT, Perplexity, and Gemini describe your brand, where you are missing, and why. Here is how to run one.
In this article
An AI visibility audit is a structured check of how AI engines like ChatGPT, Perplexity, and Gemini describe and recommend your brand when buyers ask. You run your real buyer questions through each model and record whether you appear, how accurately, and who gets recommended instead. If ChatGPT does not mention your brand, it is usually because the sources these models trust do not say enough about you, consistently, in the places they read.
This is a practical guide to running an AI visibility audit yourself and what to do with the results. Corbelix is a generative engine optimization agency for B2B SaaS and established brands, and an audit like this is the first thing we do for every client.
What an AI visibility audit measures
A useful audit goes past a single search. It measures your presence, accuracy, and sentiment across models, your share of voice against competitors, and which sources each model cites when it answers. Those four dimensions tell you not just whether you show up, but why.
- Presence: do you appear for the questions buyers actually ask?
- Accuracy: is what the model says about you correct and current?
- Share of voice: how often do you appear versus competitors?
- Sources: which pages and sites is the model citing?
How to run the audit in an afternoon
Start by listing the ten to twenty questions a buyer would ask an AI about your category, including shortlisting questions, comparisons, and how-to queries. Then prompt each major model with them and record the results in a simple sheet.
- List the real questions buyers ask, not your brand name alone
- Prompt ChatGPT, Perplexity, and Gemini with each one
- Record whether you appear, how accurately, and who is cited
- Repeat monthly so you can see the trend, not a snapshot
Why ChatGPT does not mention your brand
The most common reason is a corroboration gap: your claims live mostly on your own site, and the independent sources models trust do not echo them. Models weigh agreement across many sources, so a brand that is only described by itself tends to get skipped. The fix is to make trusted third parties describe you the same way.
For how models decide which sources to cite, see our guide to optimizing for Perplexity AI and the broader mechanics of generative engine optimization.
Turning audit findings into fixes
Each gap becomes a task. Inaccurate facts get corrected at the source, missing answers get published as clear content, and thin corroboration gets built through digital PR, Reddit, reviews, and consistent entity data. Managing that picture over time is the core of reputation management.
How often to re-audit
Once is a snapshot; monthly is a system. Models change, competitors publish, and the consensus shifts, so the brands that stay visible are the ones that re-audit, correct, and reinforce on a regular cadence.

Frequently asked questions
What is an AI visibility audit?
It is a structured check of how AI engines like ChatGPT, Perplexity, and Gemini describe and recommend your brand for the questions buyers ask, including whether you appear, how accurately, your share of voice versus competitors, and which sources are cited.
Why doesn't ChatGPT recommend my brand?
Usually because the independent sources ChatGPT trusts do not say enough about you, consistently. Models weigh agreement across many sources, so a brand described mostly by its own website tends to be skipped until third parties corroborate it.
How do I check what ChatGPT says about my company?
Prompt ChatGPT, Perplexity, and Gemini with the real questions your buyers ask about your category, then record whether you appear, how accurately, and who is recommended instead. Repeat monthly to track the trend.
