How to measure your AI visibility

Presence, share of voice, sentiment, citations, and consistency. Across every engine. What to actually track when 'are we showing up in AI?' becomes a real question.

Once a brand accepts that AI answers matter, the next question is unavoidable: how do we even measure this? "AI visibility" isn't one number. It breaks into a handful of concrete things, each answering a different question.

The five things worth tracking

Each answers a different question. You need the set, not a single number:

Metric The question it answers Why it matters
Presence Do you appear at all? The floor, if you're not mentioned, nothing else counts.
Share of Voice How do you stack up vs competitors? Whether you're winning or losing the category's AI conversation.
Citation Coverage Is your own site the source? Being cited, not just mentioned, is a concrete trust signal.
Brand Perception How are you described? "Premium" vs "budget" vs "dated". Framing shapes buyers before a human does.
Consistency How reliable is all of the above? AI is non-deterministic; reproducibility matters as much as any single reading.

Three things that make this hard to eyeball

  1. Non-determinism. The same prompt yields different answers across attempts. One check tells you almost nothing; you need repeated sampling to see the real pattern.
  2. The engines disagree. ChatGPT, Gemini, Claude, and Google's AI surfaces are built differently and will describe and rank you differently (here's why). A single-engine check is a third of the picture, at best.
  3. The surface is huge. "The questions that matter" run into the hundreds once you account for every product, use case, comparison, and the way real people phrase things. You can't hand-check that, and you can't hand-track it week over week.

A screenshot of one good answer is a vanity metric. The thing that's actually decision-useful is the trend: presence, share of voice, sentiment, and citations, sampled repeatedly, across every engine, over time.

From measurement to action

Measurement only earns its keep if it points at what to fix. The useful loop is: track the five metrics across engines → spot where you're absent, losing share, or framed badly → trace it to a cause (crawler access? thin/unstructured content? weak entity strength? a single under-performing engine?) → fix → watch the number move.

Doing that by hand. Hundreds of prompts, multiple samples each, across five engines, every day, turned into a trend and a prioritised fix list. Is exactly the job Buffy Intel automates.

Frequently asked

Can't I just ask ChatGPT how it describes my brand?

You can start there, but it won't scale or hold up. Answers shift by phrasing, by day, and by random chance; they differ across engines; and the questions that matter number in the hundreds across your products, use cases, and comparisons. A one-off check is a snapshot of one phrasing on one engine on one day, not a trend you can act on.

What's the single most important AI-visibility metric?

There isn't one, that's the point. Presence tells you if you appear; share of voice tells you how you stack up against competitors; citations tell you whether your own pages are the source; sentiment tells you how you're framed; consistency tells you how reliable all of the above is. You need the set, tracked over time.
