Frequently asked questions about Claude Seo
What is Claude SEO?
Claude SEO is a free, open-source AI SEO audit tool that runs inside Claude Code. It has 25 sub-skills and 18 subagents handling technical SEO, E-E-A-T content quality, schema markup, GEO (AI search optimization), local SEO, semantic clustering, SXO, drift monitoring, e-commerce, and strategic planning. MIT licensed with 7,000+ GitHub stars. You type one command and get the same analysis an agency would charge $5-10K/month to produce.
How do I install Claude SEO?

Is Claude SEO really free?
Yes. Fully free and open source under MIT license with no paid tiers, no freemium tricks. The core tool does everything without spending a cent. Optional extensions (DataForSEO for live SERP data, Banana for AI image generation via Gemini) need their own API keys from those services, but Claude SEO itself is $0 forever.
How does the 0-100 SEO health score work?
7 weighted categories: Content Quality (23%), Technical SEO (22%), On-Page SEO (20%), Schema (10%), Performance including Core Web Vitals with INP (10%), AI Search Readiness (10%), and Images (5%). Each audit produces a prioritized action plan with Critical, High, Medium, and Low severity levels.
Does Claude SEO work for my industry type?
All of them. Claude SEO auto-detects 5 business types from your homepage: SaaS (pricing pages, feature lists), Local Service (phone, address, service areas), E-commerce (product pages, carts), Publisher (blog, articles), and Agency (case studies, portfolios). The analysis and recommendations adapt to your specific industry.
What is GEO optimization and why does it matter?
GEO (Generative Engine Optimization) optimizes content for AI-powered search engines. Google AI Overviews, ChatGPT web search, Perplexity, and Bing Copilot now generate answers that cite sources. Claude SEO checks AI crawler access (GPTBot, Claudebot, PerplexityBot), llms.txt compliance, passage-level citability, and brand mention signals so your content gets cited.
What integrations and MCP servers are available?
Official Ahrefs MCP (@ahref/MCP), Semrush MCP server, plus community servers for Google Search Console, PageSpeed Insights, and DataForSEO. The DataForSEO extension alone adds 22 commands across 9 API modules for live SERP, keyword volume, backlink, and AI visibility data.
How does Claude SEO compare to paid SEO tools?
Ahrefs costs $99/month, Semrush costs $117/month, Claude SEO costs $0. It runs in your terminal, spawns 9 parallel AI agents, generates JSON-LD schema markup, validates against current Google requirements, and optimizes for AI search engines. The trade-off: it requires Claude Code and a terminal. If that is your workflow already, there is no reason to pay for a browser-based tool.
