AI Visibility (Share of Citations / Mention Rate)

AI Visibility is the collective term for metrics that express how much your brand or website is mentioned and cited within the answers of generative AI such as ChatGPT, Gemini, Perplexity, and Google AI Overviews; the representative metrics are "mention rate," "share of citations," "position," and "sentiment." It is the foundation for measuring the effect of LLMO/GEO work, corresponding to rankings and impressions in SEO. Main metrics: • Mention rate (Visibility) — the share of registered expected questions in which the brand name appears in the AI's answer • Share of citations (Share of AI Voice) — the share that your domain or brand occupies among the answer's cited links or all mentions; shows your relative position versus competitors • Position — where in the answer your brand is listed • Sentiment — in what context and with what evaluation you are described (positive / neutral / negative) • AI-referred traffic — visits and conversions with chatgpt.com, perplexity.ai, etc. as the referrer (measured in GA4 and similar) Mechanism and caveats: Generative AI answers vary each time even for the same question, and also differ by region, language, and login state. So the premise is not a single check but running the same prompt repeatedly and treating results as ratios, and measuring daily on a fixed schedule to watch trends. In practice: First prepare a few dozen expected questions for your category ("What is a good ...?", "... comparison"), measure mention rate and cited sources per AI, and understand where you stand. Then analyze the competitor pages and external media being cited, reflect that in your own content improvements and PR, and confirm the effect through the trend of the metrics. To start for free, you can manually pose the main questions to ChatGPT or Perplexity and record the results, and track AI referrers in GA4. Related tools: DolphinX AIO, SUPER ACT, AKARUMI, Peec AI, Profound, OtterlyAI, and AthenaHQ measure these metrics automatically on a daily basis.
