How the scores are produced

The composite Citation Index is a rollup of the frozen 25-query × 4-engine × 3-run scored benchmark documented at /ai-visibility-index. Each agency's per-engine score is a weighted blend of first-mention rate (50%), mean-rank score (25%), and total-mention rate (25%). The composite is the simple average of the four engine scores.

A representative subset of the underlying scored answers is published, with prompt and answer excerpt, at /ai-citation-log. The full 300-row scored matrix ships with the Q4 2026 report.

Any agency, analyst, or journalist can replicate the run and publish their own numbers. That is the point of publishing this table.

Want your citation share published this way?

Crackle PR runs the same protocol for client brands — quarterly, published, reproducible. An AI-visibility claim without a scored, dated URL is a claim, not evidence.
