Frequently Asked Questions

Everything you need to know about Surfer SEO vs Frase.io

Can you use Surfer SEO and Frase.io together?
Yes — this is the preferred setup for serious SEO content teams. Use Frase to research the keyword, identify questions to answer, and generate the content brief. Use Surfer in the writing phase to get real-time Content Score feedback as you write. The combination eliminates the two biggest time drains in SEO content production: research (Frase saves 2–3 hours) and optimization guesswork (Surfer provides real-time data-driven guidance).
Both tools score content against top-ranking pages for a keyword, but with different emphasis. Surfer’s Content Score weights NLP term coverage, word count alignment, and heading structure. Frase’s score emphasizes topic coverage relative to the questions users are asking and the depth of answer the content provides. Both scores improve your content for search but from slightly different angles — Surfer is stronger for competitive keyword ranking, Frase is stronger for featured snippet and AI Overview capture.
Frase.io has a Chrome extension that overlays content scoring on Google Docs, but the integration is less seamless than Surfer’s native Google Docs add-on. Surfer’s Google Docs integration is generally considered the more polished of the two for in-Doc writing with real-time scoring. Frase’s Chrome extension works but requires slightly more manual workflow management.
Surfer SEO’s Topical Map feature is specifically designed for content cluster strategy — it clusters all semantically related keywords and shows which content you need to publish to build topical authority. Frase.io is stronger for individual topic research but less developed for systematic cluster strategy planning. For content teams building topical authority systematically, Surfer’s Topical Map provides more structured strategic guidance.
Both tools have AI article writers that produce SEO-optimized first drafts. Surfer AI produces more polished prose quality (built on stronger base language models) while Frase’s AI is better at structuring content around questions and answers relevant to featured snippet capture. Neither produces publish-ready content without human editing. Surfer AI includes the Humanize feature to reduce AI detection signals. For volume AI content production with built-in optimization, Surfer AI has a slight edge in output quality.
