Understanding the scores
What the numbers mean
AI Recommendation Share
The percentage of tracked queries where this business was named by at least one AI platform. The most direct measure of how often AI is recommending you to buyers.
Composite Index Score
A weighted combination of recommendation frequency, how many platforms cited the business, position in results, and citation quality. Scores from 0 to 1.

How the CIS is calculated
Recommendation frequency
How often the business appeared across all 60 queries and all four platforms.
Platform coverage
How many of the four platforms independently recommended the business. Appearing on all four is a much stronger signal than appearing heavily on just one.
Position weighting
Where in the response the business appeared. Being named first carries more weight than being named fifth.
Citation context quality
Whether the AI cited the business with specific confident context or included it in a generic list.
