claude-seo — FAQ

What is Claude SEO?+

Claude SEO is an open-source SEO analysis plugin for Claude Code that runs 25 sub-skills and 18 specialist agents in parallel across technical SEO, content quality, Schema.org markup, AI search optimization, local SEO, e-commerce, and international SEO. It is MIT-licensed, works without third-party API enrichment, and produces prioritized action plans where each recommendation carries falsifiability checks and leading indicators.

How do I install Claude SEO?+

For Claude Code 1.0.33+, run '/plugin marketplace add AgriciDaniel/claude-seo', then '/plugin install claude-seo@agricidaniel-claude-seo', then '/seo setup' to create the isolated Python environment and install Playwright Chromium. For manual installation on Unix/macOS/Linux, run 'git clone --depth 1 https://github.com/AgriciDaniel/claude-seo.git && bash claude-seo/install.sh'.

Which AI clients does Claude SEO work with?+

Claude SEO is designed exclusively for Claude Code. A separate port called Codex SEO exists for Codex with TOML agents and deterministic runners, but shares the same SEO workflow surface.

Does Claude SEO require Google API keys?+

No. Claude SEO is fully functional with zero API keys. A 4-tier credential system lets you optionally add Tier 0 (API key for PageSpeed Insights and CrUX), Tier 1 (OAuth for Search Console and Indexing API), Tier 2 (GA4 property config), and Tier 3 (Ads developer token for Keyword Planner).

Is Claude SEO free?+

Yes. Claude SEO is MIT-licensed, fully open source, with no per-domain pricing, no telemetry, and no API quotas imposed by the plugin. Some optional MCP extensions (DataForSEO, Ahrefs, SE Ranking, Profound) require paid accounts but are not needed for core functionality.

Does Claude SEO work on single-page applications like Next.js or React?+

Yes. Claude SEO ships a headless renderer backed by Playwright Chromium that auto-detects SPA hallmarks (empty root divs, single bundle scripts, hydration markers) and switches to rendered fetches. Known edge cases include scroll-bound hydration or post-interaction content fetches, which require manual cross-checks.
