What is AI visibility?
AI visibility is the metric the other disciplines aim at. GEO, AEO and LLMO are ways to work on it; AI visibility is how you measure the result. This guide defines it, explains the two rates that make it up, and shows how to work on it.

What is AI visibility?
AI visibility is the measure of how often and how prominently your brand appears when AI assistants answer questions about your category. It's an outcome metric for generative search: it tells you whether answers to buyers asking ChatGPT, Perplexity, Gemini or Claude point toward you or toward your competitors.
Where GEO, AEO and LLMO are disciplines you practise, AI visibility is what you measure. Track it over time to see whether anything changes after your work. It is different from an AI-readiness score, which checks prerequisites on your own site.
How is AI visibility measured?
By running a fixed set of buyer questions through each assistant on a schedule and recording two things: your mention rate (how often your brand is named) and your citation rate (how often your own site is cited as a source). Tracking both, per engine, over time, is the core of the metric.
- Mention rate: how often your brand is named in the answer.
- Citation rate: how often your own site is cited as a source.
- Share of voice: your mentions compared with competitors'.
- Per engine and over time, because each assistant differs and the point is the trend.
What's the difference between mention rate and citation rate?
Mention rate is how often your brand name appears in an answer. Citation rate is how often your own site is cited as the source behind it. They can move independently: a high mention rate with a low citation rate means you're known but rarely used as a source.
Tracking them separately turns a single number into a diagnosis. Citanto reports both, per engine.
How do you work on AI visibility?
Find the questions where you're under-represented, publish structured content that answers them with your brand named, add structured data that matches the page, and earn mentions on trusted third-party sources. Then re-measure the same questions, because answers vary over time.
Citanto measures monthly mention and citation rates on four engine APIs and prepares content drafts for your review. Earning third-party mentions stays with you.

Frequently asked questions
Is AI visibility a tactic or a metric?
A metric. It's the outcome that GEO, AEO and LLMO aim to improve. Those are the disciplines; AI visibility is what you track to see whether they're working.
Can you have good SEO but poor AI visibility?
Yes. AI assistants put answers together differently from a ranked list of links, so a site can rank well in Google yet rarely be named or cited in AI answers. They're related but distinct, which is why AI visibility needs its own measurement.
How often should AI visibility be measured?
On a regular schedule with a stable set of questions, so the numbers are comparable from one period to the next. Answers vary from one run to another, so repeated samples on the same questions give a more reliable picture than occasional checks.
