Frase (Writing) and Surfer SEO (Marketing) come from different corners of the market, so this usually comes down to which job you're actually hiring a tool for, not a head-to-head on the same task.
Choose Frase if…
Best for content teams who want a research brief built from what's already ranking, before writing begins, and its edge is pulls the top 20 search results for a keyword and turns their structure into an optimized content brief automatically. Excellent for the research phase specifically, its own AI writer is a secondary feature at best. Lean toward Surfer SEO instead if a live Content Score that shows exactly which semantic terms and entities your draft is missing as you write matters more for your use case.
Choose Surfer SEO if…
Best for content teams optimizing existing articles to compete with the top-ranking pages for a keyword, and its edge is a live Content Score that shows exactly which semantic terms and entities your draft is missing as you write. The best content-scoring tool available, better for optimizing a draft than generating one from nothing. Lean toward Frase instead if pulls the top 20 search results for a keyword and turns their structure into an optimized content brief automatically matters more for your use case.
