How this benchmark is built

Citation share is calculated from the Trakkr Citation Index across observed AI answer citations.

The public snapshot includes the top source domains plus aggregate metadata from the latest slim index.

Unique URL and brand counts show how broadly a domain is cited, not just how often it appears.

Coverage window: 2025-10-03 to 2026-06-10.

[05]FAQ

What is citation source share?

Citation source share is the percentage of observed AI answer citations that point to a domain within the Trakkr Citation Index.

Why do some domains rank highly?

Domains rank highly when AI systems repeatedly cite their pages across brands, queries, and categories. The table includes unique URL and brand counts to separate depth from breadth.
