What is AI visibility? · Rankdelta

AI visibility is how often answer engines mention or cite your brand. It is not a Google position, and it is not a traffic channel by itself.

AI visibility is how often, and how prominently, an answer engine mentions or cites your brand when people ask questions in your category.

Semrush’s GEO guide frames the same idea as competing to be part of the output, not only to rank in a list of links. Metrics they name: AI visibility, mentions, citations, share of voice. We use those words the same way. We do not invent a proprietary index number.

What it is not

  • Not position. Classic rank tracking still answers a different question. Keep it.
  • Not a GSC click. A citation without a click can still shape the shortlist a buyer hears.
  • Not “we asked ChatGPT once.” One session is a demo.

Google Search Central: AI Overviews appear when they are additive; they use query fan-out; eligibility is indexed + snippet. That is the Google slice of AI visibility, not the whole thing.

How to measure it without a fake score

  1. Freeze 20–40 prompts a buyer would actually ask.
  2. Sample ChatGPT, Perplexity, and Google (AI Overviews / AI Mode) on a weekly cadence.
  3. Code each run: cited, mentioned, absent.
  4. Watch your time series on one tool. Do not mash Profound SOV into Peec SOV.

First-party Google layer: Performance (Web) plus, where rolled out, the Generative AI performance reports (impressions, pages, countries, devices, dates — subset of sites as of the 3 June 2026 announcement).

Rankdelta citation rate of 42% and average position #1 among cited brands for a demo project

Two separate measurements on one demo project (visitvaldinoto.com): 42% of AI answers link to the site, and when it is cited it comes first. Neither number says how often the brand is named in the text, which is a third measurement.

Tools vs definition

Definitions do not require a purchase. Tools do. See AI visibility tools for the tracker vs writer split, AI Overview tracking for the Google sampler, ChatGPT SEO tool for the ChatGPT-shaped query. To test whether AI names you, run an AI visibility checker.

Rankdelta tracks AI visibility and includes a Content Writer. Disclosure: this is our product; we have no independent study proving a visibility lift percentage.
