Surfer SEO

Surfer SEO analyzes the top-ranking pages for a target keyword and turns that analysis into a content score, term suggestions, and structural guidance (headings, word count, image count) that you edit against in real time. Its AI features build on this: generating outlines and full drafts that are pre-optimized against the same scoring model, plus a site audit tool that flags on-page SEO issues across your existing content and suggests internal links. It integrates with Google Docs and WordPress so the scoring panel sits alongside your normal writing workflow. There's no free tier, and pricing starting around $89/mo is steep for solo creators compared to general AI writing tools — the trade-off is that Surfer's recommendations are grounded in actual current SERP data rather than general writing advice. Following the score too literally can encourage keyword-stuffing, so it works best as a guide alongside genuinely useful content rather than a target to maximize.
