The Best SEO Agencies in the World: 2022 Edition

This report takes a quantitative approach to determining the best SEO agencies in the world. Our team created a weighted algorithm based on a combination of external signals (e.g. publicly available clients, online reviews, online reputation). The main factors in our analysis are listed below, along with each factor’s respective weight in our algorithm. 

  • Years in Business: This factor evaluates SEO agencies on longevity alone, given that surviving the business world as well as Google’s many algorithm updates proves some degree of adaptability and commitment to sound SEO strategy. [ Algorithm weight: .14 ]
  • Agency Size: This factor favors slightly larger firms (which, in the world of SEO agencies, means 50+ employees) as they’re likely to have more resources to devote to each client as well as longer-tenured employees.  [ Algorithm weight: .18 ]
  • Headquarters Location: This factor matters only insofar as it hints at how plugged-in a company is to high quality employees, SEO events, and the tech community at large. We give location the least weight in our algorithm. [ Algorithm weight: .09 ]
  • Client Success Score: This numerical value evaluates an agency’s past clients, awards, and reviews. [ Algorithm weight: .26 ]
  • Online Reputation Score: This metric is based on the SEO agency’s employee reviews and the favorability of language about it on popular social media channels.  [ Algorithm weight: .18 ]
  • Notable Clients: This factor evaluates an agency on the notability of the companies that have either publicly mentioned their partnership or are listed on their website. [ Algorithm weight: .15 ]

The table below rank orders the 20 SEO Agencies that had the highest overall rating in our study. We further refine the dataset by listing each agency’s stated SEO specialty and price range.
