AI share of voice
also called Share of Voice %AI answer share of voiceSoV
Definition
A single figure combining how often answer engines cite you and how often they name you, expressed as a share of the same weighted total across the tracked competitor set.
How it's calculated
(1.25 × your citations + 1.0 × your mentions) ÷ (1.25 × all tracked domains' citations + 1.0 × all tracked domains' mentions) × 100. The numerator is the AI answer presence score; the denominator applies the same two weights to the whole tracked set.
- Numerator
- Your citations weighted 1.25 plus your mentions weighted 1, the AI answer presence score.
- Denominator
- The same weighted combination computed over every tracked domain, you included.
Scope, grain and dimensions
- Grain
- One competitor domain (including your own), answer engine, intent, country, device or brand bucket for one tracked segment over one date range.
- Dimensions
- competitor domain · answer engine · intent · country · device · branded vs non-branded
- Required filters
- tracker (unified segment id) · date range
- Aggregation
- Never average the per-engine percentages for a cross-engine figure, the semantic layer re-aggregates the ratio on a measure-only read. The competitor, intent, geography and brand tabs rank rows by this measure; the prompt tab ranks by mentions and the cited-URL tab by citations, so a share-of-voice ordering is not universal across the drilldown.
- Metric type
- share · percent of tracked answer-engine voice

How to read it
Read as standing against the tracked competitor set, not as a share of all AI answers everywhere. Because it folds two behaviours into one number under fixed weights, a move is a prompt to look at the citation and mention columns underneath it rather than a finding on its own.
Caveats, freshness and failure modes
The 1.25 and 1.0 weights are a product decision carried in the semantic layer, not a quantity any engine reports. The ordering changes if the weights change.
The measure read by these verbs is the position-agnostic one. An older position-weighted variant still exists beside it, labelled "Share of Answers (%)"; it is deliberately not read, so a figure quoted from an older report may not match.
Absence from the standings means untracked, not absent, a competitor the segment does not track cannot appear in the denominator or the ranking.
Every figure is scoped to a tracked prompt basket, a sample, not a census, so the basket's coverage belongs beside the number it produced.
- Freshness
- ~1 day behind, Daily prompt runs, available the following day.
Common failure modes
- Reading it as a share of the entire AI-answer market rather than of the tracked competitor set.
- Explaining a share-of-voice move without checking whether it came from the citation half or the mention half.
- Comparing it against a figure produced by the deprecated position-weighted variant, which carries a different formula and an adjustment constant.

The confusions that cause the most wrong decisions.
AI share of voice AI citation rate Compare definitions →
Share of voice is the weighted blend of citations and mentions over the tracked set; the citation share is citations alone over the same set. They share a denominator family, so the gap between them is entirely the mention half.
AI share of voice Prompt share-of-voice percentage Compare definitions →
Same weights, two grains and two implementations. This one is a semantic-layer measure over the whole slice; the prompt-level one is computed in the verb per prompt, dividing your weighted voice by every cited domain's weighted voice for that prompt. Neither decomposes into the other.
AI share of voice AI Overview inclusion Compare definitions →
Share of voice is measured on answer-engine responses; AI Overview inclusion is Google's on-SERP feature on a different dataset. Neither is folded into the other.
AI share of voice Search market share Compare definitions →
Both get called "share of voice". This one is CTR-modeled search market share of tracked demand on the Google SERP; the other is share of answer-engine responses. Different surfaces, different denominators, and they move independently.
AI share of voice Prompt share-of-voice score Compare definitions →
A share and the points total it is built from. The score is your weighted voice alone; this is that score over the tracked set's weighted total. The score rises with basket size; the share does not.
AI share of voice Your rank in AI answers Compare definitions →
A position and the quantity it was ordered by. Share of voice can fall while the rank holds, and the rank can fall on a share-of-voice gain if a rival gained more.
