Definition
AI visibility is how often and how favorably AI assistants mention, recommend or cite your brand when people ask questions related to what you sell.
AI visibility explained
In classic SEO, visibility is measured with rankings and impressions. In AI search there is no fixed ranking to track: answers vary by assistant, wording, location and day. AI visibility is therefore measured by sampling. You run a set of realistic prompts across assistants such as ChatGPT, Gemini, Perplexity and Claude, repeatedly, and record what they say.
The main things to record are:
- Mentions: whether your brand is named in the answer.
- Position and tone: whether you are recommended first, listed among others, or described with caveats.
- Citations: whether your own pages are linked as sources.
- Accuracy: whether prices, features and other facts about you are correct.
- Competitors: which brands appear when you don't.
Tracked over time, these give you a baseline and show whether GEO work, new content or press coverage is changing how assistants talk about you.
Example
You run a fixed list of buyer prompts, such as “best payroll software for startups”, across four assistants every week. Your brand appears in some ChatGPT answers but none on Gemini, and Perplexity quotes an outdated price. That picture is your AI visibility, and it tells you where to start.
Why it matters
What an assistant says about your brand now shapes shortlists before buyers ever reach your site. You can only improve it once you measure it.
