How to read this board
Scores come from a fixed query pool, run weekly across Core-3 engines, then averaged.
Week · Pool · Engines
Week is the ISO week published. Pool is the benchmark version (e.g. v0.1). Engines are the AI surfaces included in this Index.
Mention vs Citation
Mention rate: share of Core queries that name the brand. Citation rate: share that link the brand’s domain. Citation weighs more in Index.
Index ranking
Rows are sorted by Index. A high Mention with low Citation means the brand is talked about but rarely attributed as a source.
Formulas and engine rules are in Methodology. Pro monitor shows per-query wins and losses.
