Companies 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. Companies with equal views share a rank.
A company 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 companies are listed and viewed for it to be meaningful.
A ranking reflects interest in a company's listing. It is not an endorsement, and it is not a check of a company's competence, certification or accreditation.
