This directory's ratings on a 1-10 scale.

This section weighs the public evidence of the agency's credibility, breaking down each piece of evidence by its category ("Type"), a description, and how strong it is ("Strength").

This directory's estimate of how the published practice splits across work types. It is not a mix the agency disclosed.

This section ranks the public proof behind the agency from strongest to weakest. Each rung is a different standard of proof. Independent Third-Party Coverage is a writeup by someone else. Named Case Studies are published case studies with a client named. Claimed Clients are names the agency lists as clients. Anecdotes are quotes. The right column lists the evidence we found for this agency at each rung.
