How often and how prominently a brand or source appears in AI-generated answers.

Also called: visibility in AI search, LLM visibility, generative search visibility

What is AI visibility?

Direct answer

How often and how prominently a brand or source appears in AI-generated answers.

AI visibility is the measurable presence of a brand, product, person or website across answers generated by ChatGPT, Perplexity, Gemini, Claude and Google AI Overviews. It includes citations, unlinked mentions, recommendation position, sentiment and the share of relevant prompts where the entity appears.

It is broader than traffic. A buyer may see a recommendation without clicking, so a complete view combines answer-side exposure with AI referral attribution. The practical goal is not to appear everywhere; it is to appear accurately for the questions that influence discovery and purchase.

Why — and when — does it matter?

Use AI visibility to answer the broad business question: when the right audience asks AI for information or a recommendation, are you present, accurate and competitive?

How it works

1

Define the market, audience, geography and engines.

2

Build prompts across discovery, comparison, objection and purchase stages.

3

Record cited, mentioned or absent plus position and sentiment.

4

Compare competitors and trend the same sample over time.

5

Connect resulting visits and conversions where possible.

Worked example

Situation → interpretation → action

An e-commerce store tracks 60 questions about hiking footwear across four engines. It appears often for informational questions but is absent from product comparisons, revealing a commercial-visibility gap hidden by the overall score.

How to track and report it

PrimaryPrompt coverage and citation rate
SecondaryShare of voice, recommendation rate, sentiment and AI revenue
FormulaVisibility coverage = prompts where cited or mentioned ÷ eligible prompts × 100

Reporting rule: State the engine, prompt set, market, time window and denominator. A number without scope cannot be reproduced or compared.

Practical playbook

  1. Define the market, audience, geography and engines.
  2. Build prompts across discovery, comparison, objection and purchase stages.
  3. Record cited, mentioned or absent plus position and sentiment.
  4. Compare competitors and trend the same sample over time.
  5. Connect resulting visits and conversions where possible.

Common mistakes

  • Using one vanity prompt
  • Mixing markets or languages in one trend
  • Reporting exposure without accuracy or business outcomes
