Where They Differ
Brief quality: Frase.io is the clear winner
Frase pulls the top 20 SERP results for your target keyword, extracts their headings, word counts, and key topics, and assembles a research-backed brief in under 2 minutes. The brief quality is higher than anything Surfer produces. For content editors who brief freelancers or scale a writing team, this alone justifies Frase’s cost.
Optimization depth: Surfer wins
Surfer’s Content Score is more granular, more predictive, and more respected than Frase’s optimization score. Surfer analyzes entity density, exact-match keyword frequency, structural signals, and hundreds of NLP features. In ranking experiments, Surfer-optimized content consistently outperforms Frase-optimized content when all else is equal.
Can you use both?
Yes — and it’s a legitimate strategy. Use Frase to build the brief and structure the content, then run the finished draft through Surfer’s editor to optimize before publishing. The combined cost ($45 + $89 = $134/mo) is higher than either alone, but it’s the strongest possible SEO content workflow if budget allows.
