Methodology

What's counted: every citation/source URL returned by citation-capable AI models for Mexico-market projects across the rolling 4 ISO weeks, aggregated from every analysis run on BrandInsightAI. Citations deduplicate to one registrable domain per model response.
Quality gate: a domain must appear across ≥ 2 distinct projects to be named; shares are computed against ALL citations in scope, so the gate hides names, never distorts percentages.
Movers: week-over-week comparisons use the two most recent COMPLETE ISO weeks (2026-08-03 → 2026-08-17); the in-progress week is excluded because it refreshes hourly, and a domain must clear the citation floor in BOTH weeks — so a newly monitored category entering the dataset never shows up as a gainer.
Freshness: the snapshot behind this page recomputes every hour. All figures are measured, never estimated.
