Method & limitations
Shares are of all citations captured by the platform that week (42,740 citations, 9,403 responses), a large, continuously refreshed sample, not a census of AI answers.
Only domains cited across at least 2 independent projects AND clearing 25 citations in both weeks qualify, a domain appearing from zero reflects new monitoring coverage, not a genuine move, and is excluded. Movement of ±0.2pp or less is treated as noise.
Week-over-week movement is descriptive, not causal, a spike can reflect model behaviour, news cycles, or the mix of questions asked.
How every figure on this page is counted, floored and
