Top SaaS SEO Agencies: 2023

Our team evaluated 63 SaaS-centered SEO agencies to determine the most successful firms based on their SaaS industry experience. We rank-ordered the companies using the following criteria:

  • Notable Clients (35%): An agency’s experience with notable SaaS clients is the best indicator of their ability to run successful SEO campaigns. As such, it is the factor to which we assign the most weight.
  • Leadership Experience (25%): We assigned each company numerical score from 1 to 5 based on the SaaS marketing experience of each agency’s top executives and marketing leadership.
  • Company Size (20%): Although size is not inherently tied to skill, larger companies are both capable of providing a level of support and have the internal infrastructure required for executing complex SaaS SEO campaigns. To grow to a significant size, companies must also maintain strong client retention rates based on successful work.
  • Year Founded (15%): Despite being a relatively new marketing industry, SEO has evolved significantly over the past 15 years. The length of a company’s tenure displays its ability to update its SEO strategy as Google updates its algorithm, as well as weather market cycles and economic downturns.
  • Headquarters (5%): SEO agencies in major cities benefit from access to a more diverse talent pool, and a wider array of industry connections, making headquarters location a small but relevant consideration in our ranking.

For each agency below, we also provide their Main Focus, describing their unique approach to SEO. The results of our research are presented in the table below:
