SerpX is an all-in-one AI SEO platform for analyzing websites, researching keywords, and tracking competitors. Its core toolset includes an AI SEO Audit that scores site health and flags technical issues, a Competitor Spy and Keyword Gap Finder for uncovering keywords competitors rank for, and a Technical SEO Fixer for surfacing crawlability, indexing, and on-page problems. Users generate one-click SEO reports from any URL, manage reports across unlimited websites on paid plans, and consume credits for AI-driven analyses and content generation. SerpX also offers a free WordPress plugin that connects a WordPress site to its AI SEO workflows, keyword research, and content optimization tools, plus a REST API (Websites, Reports, and Account endpoints) for programmatic access on paid plans. The platform targets marketers, freelance SEOs, agencies, and developers who want AI-assisted audits and reporting without stitching together multiple separate SEO tools.

REST API (Websites, Reports, Account endpoints) enables programmatic reporting for agencies and developers on paid plans

Cons
