How we score agencies

Every agency gets an IC Score out of 100, built from seven weighted factors. All inputs come from publicly available information — review platforms, the agencies' own websites. Scores are refreshed monthly.

25%

Client reviews

Average rating across major review platforms, adjusted for review volume so 5 reviews can't beat 300.

20%

Verified clients

Named clients and brand logos we could verify against public sources.

15%

Campaign track record

Published case studies with concrete, checkable results.

10%

Pricing transparency

Published pricing, minimum budgets, or rate ranges score higher than "contact us."

20%

Niche specialization

Share of public work and case studies in this specific niche.

10%

Team & stability

Years in operation and team size, from public company information.

Scores reflect publicly available information as of August 2026 and are opinions based on the methodology above, not statements of fact about service quality.
