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
- 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.
- 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.
- 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.
