Surfer SEO

Surfer SEO is an AI-assisted search optimization and content optimization platform. While tools like Writesonic focus mainly on writing, Surfer aims to align drafts and existing articles with what Google (and increasingly AI search) expects.

Its core is SERP / competitor analysis: after you enter a keyword, Surfer derives patterns from top results (length, phrases, structure, media, etc.) and gives live guidance and a Content Score while you write.
