How the rankings work

Firms are ranked by how often their OpenFire directory profile was viewed during the calendar month, by people and by AI assistants. Search-engine crawlers, other automated traffic and link previews are not counted. Firms with equal views share a rank.

A firm with offices in several countries, or working across several categories, is ranked in each of them on the same monthly total. A ranking is only published where enough firms are listed and viewed for it to be meaningful.

A ranking reflects interest in a firm's listing. It is not an endorsement, and it is not a check of a firm's competence, certification or accreditation.
