How to read this board

Scores come from a fixed query pool, run weekly across Core-3 engines, then averaged.

  1. 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.

  2. 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.

  3. 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.
