  "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.",
  "category": "AI visibility",
  "type": "share",
  "unit": "percent of tracked answer-engine voice",
  "direction": "higher-better",
  "verification": "verified",
  "calculation": "(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.",
  "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.",
  "grain": "One competitor domain (including your own), answer engine, intent, country, device or brand bucket for one tracked segment over one date range.",

  "questions": [
    "What is our share of voice in AI answers?",
    "Who leads share of voice on this tracker?",
    "Is our share of voice improving per engine?"
  ],
  "interpretation": "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": [
    "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."

      "slug": "ai-citation-rate",
      "why": "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."

    {
      "slug": "prompt-share-of-voice-share",
      "why": "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."

      "why": "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."
