Learn AI visibility
The concepts behind measuring your brand in AI answers, defined precisely and without the hype, so you know exactly what a score means before you chase it. Start with Share of AI Answer for the metric itself, or why web-grounded measurement is non-negotiable for the single technical decision that determines whether any of these numbers are real.
- What is Share of AI Answer?The share of tracked question-engine pairs where an AI assistant cites your brand. The formula, how to measure it honestly, and what a good score looks like.
- Why web-grounded measurement is non-negotiableAn AI model without web search invents citations that look real. Why visibility measurement must run in grounded mode, and the mechanism each engine uses.
- What is answer engine optimization (AEO)?AEO, also called GEO, is the practice of making your brand more likely to be cited by AI assistants. How it works, how it differs from SEO, and how to measure it.
- How do AI assistants choose their sources?ChatGPT, Claude, Gemini, Perplexity and Grok ground answers with live search. How source selection works, what gets cited, and why the engines disagree.
- AI visibility metrics that matterShare of AI Answer, per-engine citation rate, competitor win rate and answer-source mix: the four metrics worth tracking, and the vanity ones to skip.
What do you need to understand before tracking AI visibility?
Three things, in this order. What the metric is and how it is computed; why every query has to run with live web search enabled; and which of the many numbers you could report actually support a decision.
- What is Share of AI Answer — the formula, what counts as a citation, and why failed calls must be excluded from the denominator.
- Why web-grounded measurement is non-negotiable — how each engine grounds, and why an ungrounded model fabricates citations that look real.
- What is AEO — answer engine optimization versus SEO, and what genuinely moves citations.
- How AI assistants choose their sources — retrieval, synthesis, and why engines disagree with each other.
- AI visibility metrics that matter — the four worth tracking and the vanity metrics to skip.
Where do you go after the concepts?
To the engine you care about most, then to the work. The track guides cover how to measure each of ChatGPT, Claude, Gemini, Perplexity and Grok specifically, including how each one grounds its answers and what it tends to cite. The get cited guides cover what to do once you know which questions you lose.
If you are evaluating tools rather than concepts, how AI Visibility Tracker compares puts the whole category side by side, with prices read off each vendor’s own page and stated limitations on our side.
Frequently asked questions
What is AI visibility?
AI visibility is how often, and how favourably, AI assistants name or cite your brand when answering the questions your buyers ask. It is measured as Share of AI Answer — the percentage of tracked question-engine pairs where your brand appears — rather than as rankings or traffic.
What is the difference between AEO, GEO and AI SEO?
They are three names for substantially the same practice: making it more likely that AI assistants cite your brand. AEO (answer engine optimization) and AI SEO are the common industry terms; GEO (generative engine optimization) is more common in academic writing. None of them describes a different technique.
