    "Decay describes observed persistence, not the full causal mechanism behind why a citation disappears.",
    "Brand- and domain-level averages can hide very different retention patterns by query class or model.",
    "Some of the stickiest or most volatile domains come from niche query pockets and should be read as examples, not universal leaders."

  "question": "How fast can AI visibility drop after a peak?",
  "directAnswer": "Usually, very fast. The study shows that 47.1% of brands halve their visibility within 7 days, with an average weekly mention change of 51.8% and an average daily mention change of 30%.",
  "answerSummary": "Teams that check visibility too slowly can miss the full shape of a rise and collapse, leading to inaccurate performance assessments.",
