Methodology
The population is the 3,460 US growth-services vendors listed in The Wall on the as-of date: marketing, SEO, creative, content, social, PR, automation, demand generation, sales, and AI marketing firms that sell to established businesses. It is a large directory, not a random sample of every US agency, and results describe it.
Google ratings and the per-star review counts come from each firm's Google Business Profile, matched to the firm by its website domain (1,032 matched profiles with at least one review). Clutch ratings come from Clutch profiles for the 1,418 firms whose record is sourced from Clutch. Firms "rated on both" have at least 5 Google and 3 Clutch reviews.
Google shows a rating to one decimal. Star counts are as Google reports them on the profile.
Every figure on this page is computed by one script from The Wall's records and is reproducible from the CSV above. Full sourcing rules: methodology. Corrections: editorial and corrections policy.
