  "definition": "A weighted points score for how much of an answer-engine prompt's voice you hold, counting each citation as 1.25 and each mention as 1.",
  "category": "AI visibility",
  "type": "score",
  "unit": "weighted points (citations weighted 1.25, mentions weighted 1)",
  "direction": "higher-better",
  "verification": "verified",
  "calculation": "score = 1.25 × your citations for the prompt + your mentions for the prompt, rounded to a whole number. Both inputs are filtered to your own domain before the weighting is applied.",
  "aggregation": "A points total per prompt. Not comparable across segments or periods with different basket sizes, and not a component of the percentage beside it, that percentage divides this score by the same weighted total across every domain on the prompt, not by a sum of your scores.",
  "grain": "One prompt for one tracked segment over one date range.",

  "questions": [
    "Which prompts carry most of our AI voice?",
    "Where does the weighting change the ranking versus raw citations?"
  ],
  "interpretation": "The weighting encodes an editorial position, a citation is worth more than a mention because it is the earned-source signal, and it is the same weighting the semantic layer applies in its own presence score, so the prompt score is a grain of an existing product quantity rather than a verb invention. Use it to order prompts, not to state a level.",
  "caveats": [
    "The 1.25 weight is a product constant, not an engine-reported quantity. It matches the semantic layer's presence score, so the two agree by construction rather than by coincidence.",
    "The prompt tab reads the market-share rank and brand-mention datasets. If the tracker has no market-share segment for the requested engine the tab returns no rows with a stated reason.",
    "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.",
    "Engines are non-deterministic: the same prompt can answer differently twice, so a prompt's score is an observation total over repeated runs."

  "freshness": "~1 day behind, Daily prompt runs, available the following day.",
  "failureModes": [
    "Comparing scores between two segments or two periods whose baskets differ.",
    "Reading the score as a percentage, it is an unbounded points total."

    {
      "slug": "prompt-share-of-voice-share",
      "why": "The score is your weighted points total on the prompt; the percentage is that total over every domain's weighted total on the same prompt. Both are well defined and neither is derived from the other by summing prompts."
    },
    {
      "slug": "ai-share-of-voice",
      "why": "The same weights at two grains: this is computed in the verb from one prompt's counts, while the grid and competitor tabs read a semantic-layer measure over the whole slice."
