How this ranking works
Agencies are ranked by the number of client relationships we could verify from public pages, such as the agency's own client and case-study pages. Every relationship carries a source link and a confidence label, and we count only relationships that have a working source. Ties go to the agency with more brands verified through Meta access, then alphabetically. Verified status is shown next to each agency but does not change the rank.
What it is not: a quality score or a recommendation. An agency with no public client page ranks low even if its work is excellent. Evidence shows a relationship existed when published, not that it is current. Agencies can claim their profile for free to add or correct details, and connect Meta to earn the Verified badge.
