Claude SEO
AgriciDaniel/claude-seo
Claude SEO is an MIT-licensed plugin for Claude Code from the maker agricidaniel. It runs 26 sub-skills and 19 specialist agents in parallel across technical SEO, content quality, schema markup, AI search optimization, local SEO, e-commerce and international SEO. Each audit produces a prioritized action plan with a 0 to 100 score, and every recommendation carries a check for how you would know it failed.

How to install Claude SEO
| Agent | Command | Copy |

Commands as given in the README on 3 October 2026.
What Claude SEO runs on your machine
- Hooks
- Yes. A PostToolUse hook runs a Python schema validator after every Edit or Write, through a small Node wrapper.
- Bundled scripts
- Yes. /seo setup creates an isolated Python environment in Claude's plugin data and installs Playwright Chromium. Audits render pages with a shared Python script. Python 3.10 or later is required, and the README advises 3.11 or newer.
- Network calls
- Yes. Audits fetch the URLs you point them at. The README says the free tier makes no third-party API calls by default. Optional Google API credentials and extensions call outside services, and the README says there is no telemetry.
- API keys needed
- None required. The README describes four optional tiers, starting with a Google API key for PageSpeed Insights and CrUX. Some extensions need paid accounts.
These are facts read from the repo, not a security rating. Read the files before you install any skill.
What is inside Claude SEO
| Skill | What it makes the agent do |
|---|---|
| /seo audit | Full website audit that fans out up to 17 specialist agents in parallel. |
| /seo page | Deep single-page analysis of on-page elements, content quality and schema. |
| /seo schema | Detects, validates and generates Schema.org markup. |
| /seo geo | AI search optimization with passage citability scoring. |
| /seo sitemap | Generates a sitemap from industry templates. |
| /seo setup | Creates or refreshes the isolated Python runtime and Chromium. |
| /seo doctor | Checks that the setup is healthy. |
| /seo dataforseo | Live SEO data through an optional extension that needs a DataForSEO account. |
The count of 26 is the README's figure for sub-skills in the core plugin. The repo also holds optional extensions, such as DataForSEO, Ahrefs, Firecrawl and Bing Webmaster, which add further skills.
A good fit for
- SEO agencies that run recurring audits across many client sites
- In-house SEO leads who want a second review before an executive meeting
- Freelance consultants who want a quick scored audit to open an engagement
- Teams that care about AI search visibility, since a dedicated GEO skill covers it
Skip it if
- Agents other than Claude Code, because this plugin targets Claude Code
- Machines where Python and Chromium cannot be installed
- Teams that want no hooks, since a schema validator runs after file edits
How Claude SEO works
The plugin is aimed at agencies, in-house SEO leads and freelance consultants. A full audit runs agents for technical SEO, content, schema, performance, GEO and more, then merges the results into one prioritized plan.
The README says every recommendation includes the observation it rests on, its dependencies, a check for how you would know it failed, and a leading indicator. It also lists a limitation: heavy client-side hydration can still trip the headless renderer on some single-page apps.
