How we rank

We rank marketing agencies like a product reviewer ranks products, not like a directory. Every listing passes the same qualification bar before placement is considered.

Scoring criteria

Each category has its own weighted rubric (plumbing weights differ from legal). In every rubric:

Niche depth — what share of their clients are in this vertical.
Tenure in niche— how many years they've specialized.
Client retention — average engagement length.
Verifiable results — real case studies with real numbers.
Owner accessibility — founder-led operations.
Team specialization — dedicated staff for the niche.
Proprietary IP — playbooks, software, or methodology.
Industry participation — trade events, publications, associations.

Disclosure

Some agencies on our lists are members of a paid network. Membership never qualifies an agency for a list — qualification is earned on editorial criteria alone. Within qualified agencies, membership can influence placement in Editor's Picks. Every page where this applies carries a disclosure line, and individual listings are labeled "Featured."

Annual refresh

Every listing is re-scored annually against current criteria. Prior editions are preserved at year-versioned URLs so buyers can see how our view changed.
