AI Share of Voice™

The percentage of AI-generated buying answers that recommend a given brand, measured across ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews. Where SEO rank measures presence, AI Share of Voice measures preference the share of recommendations that actually go to you.

It is calculated by running a curated bank of buyer prompts (typically 100+ per category) through every tracked engine on a fixed cadence, then weighting each captured mention by prompt search volume, position within the answer, and engine reach.

SOVbrand = Σ ( mentions × position weight × engine reach ) ÷ Σ ( total weighted answer slots )
Score bands

Four bands. One spectrum.

Where you sit on the AI Share of Voice spectrum determines how AI surfaces you in buyer answers and what you have to do next.

31 – 55%

At Risk

You appear in some answers, often after a competitor. One model update, one new entrant, and you're back in invisible territory.

56 – 75%

Strong

AI recommends you in the majority of category prompts, usually in the first or second slot. You're winning the buyer's first answer.

76 – 100%

Dominant

You are the default answer. Buyers asking AI for your category get you, by name, first, with framing in your favor.

Calculation

How we compute it.

Every score is reproducible. We run the same prompts, on the same cadence, weight each mention with the same constants, and publish the methodology. No magic.

Step 01 · Prompts

Curated bank, real buyers.

Our index covers 10,000+ category prompts ranked by commercial intent. Per category, we use 100+ the questions buyers actually type into AI before purchasing.

Step 02 · Capture

Verbatim from every engine.

Each prompt runs across all five engines. We log the verbatim answer, the brands named, the order of mention, and any cited sources every cycle.

Step 03 · Score

Weight, aggregate, publish.

Mentions weighted by prompt volume × position × engine reach. Aggregated to a single 0–100 composite, plus per-engine and per-prompt drilldowns.

Why it matters

Why it beats traditional metrics.

SOV measures the right thing in the right place: did AI tell the buyer to choose you?

SEO Rank #1vs.AI SOV 64%

Rank measures presence. SOV measures preference.

You can rank first on Google and never get recommended by AI. SOV captures the actual choice the buyer is given not the list of choices that exist somewhere.

Share of searchvs.AI Share of Voice

Search volume measures intent. SOV measures outcome.

Share of search tells you what people are typing. AI Share of Voice tells you which brand they're being told to pick. Different question, different answer.

Brand awareness surveysvs.AI Share of Voice

Surveys measure memory. SOV measures recommendation.

Awareness asks "have you heard of us?" SOV asks "did the AI recommend us?" Only one of those moves a sale forward.
