Claude SEO

Claude SEO is an open-source SEO analysis plugin for Claude Code by Agrici Daniel. It audits a site for technical SEO, structured data, content quality, and whether the site shows up in AI search results. The core has 26 skills (an entry point plus 25 sub-skills), the README lists 19 specialized sub-agents, and there are 9 optional extensions. It's a third-party plugin, not an official Anthropic product.

Who it's for:Site owners, SEO specialists and marketers who want to audit their own websites.

Before you start: You need Claude Code, which requires its own account and payment method; the plugin itself is free and needs no membership. The core visits the URLs you audit, and site content goes into the AI assistant's context. Optional extensions connect to services such as Google (GA4, Search Console, Ads), DataForSEO, Firecrawl and Ahrefs, sending domains, URLs, keywords and similar data; each needs its own account and may cost money. IndexNow and Indexing submit URLs to outside services on your behalf, so they aren't read-only. The installer writes to ~/.claude/skills and agents and creates a separate Python environment, and the plugin registers a hook that reads files right after you edit or write them to check JSON-LD structured data. AI Inspiration World doesn't recommend installing with curl piped into bash without reading it first; download and review the script, then use the core features on sites you own. The README promotes a paid Skool Pro community, which isn't needed to use the plugin. MIT-licensed.
