Semrush's 26B keywords and 43T backlink index are in a completely different league.
Surfer's real-time NLP scoring and shareable writer links are faster than Semrush's SEO Writing Assistant.
Semrush crawls 140+ technical SEO & Core Web Vitals checks; Surfer does not crawl technical site architecture.
Surfer includes 5–10 seats + shareable links; Semrush charges $45–$100/mo per extra user seat.
Comparing Semrush and Surfer SEO is a frequent point of confusion for B2B marketing directors. While Semrush includes an on-page writing assistant and Surfer includes keyword clustering, they solve two distinct stages of the organic growth funnel: Semrush tells you what to build and why competitors are winning; Surfer SEO helps your writers engineer the exact page to outrank them.
No. Surfer SEO does not include backlink auditing, technical site crawl diagnostics, or competitor PPC intelligence. High-performing B2B teams use Semrush Pro/Guru (1 seat) for strategy and Surfer SEO for content execution.
