What is Surfer SEO?
Surfer SEO is an on-page content optimization platform that analyzes top-ranking pages for any keyword, extracts 500+ ranking signals, and translates them into actionable recommendations writers apply while writing. The core feature is a Content Editor with real-time scoring (0-100) that shows exactly which keywords to include, heading structure, word count targets, and NLP entities to cover.
