claude-seo
claude-seo is the skill this site uses for its SEO and GEO audits. It covers technical SEO, E-E-A-T, structured data, GEO/AEO, backlink analysis, local SEO, semantic clustering, e-commerce and international SEO, with optional DataForSEO and Firecrawl extensions. Maintained by a third-party developer, with regular updates (a personal contribution on JSON-LD block truncation was in fact merged into a more robust version).
Key advantages
- 25 sub-skills covering nearly every aspect of modern SEO
- Extensible with third-party data sources (DataForSEO, Firecrawl)
- Active community, bugs reported and fixed quickly
Who it's for, and why
SEO consultants and technical teams who want a structured, repeatable audit directly from Claude Code, without a separate SaaS tool.
- Full technical audit of a site (crawlability, indexing, security)
- Checking structured data and GEO citability
- Backlink analysis and semantic clustering
Getting started
- 1Quick install (Claude Code 1.0.33+): `/plugin marketplace add AgriciDaniel/claude-seo` then `/plugin install claude-seo@agricidaniel-claude-seo`.
- 2Run setup: `/seo setup`, which creates an isolated Python environment and installs Chromium for Playwright, without touching global packages.
- 3Check the install at any time with `/seo doctor`.
- 4Manual alternative: `git clone --depth 1 https://github.com/AgriciDaniel/claude-seo.git && bash claude-seo/install.sh`.
Things to watch out for
- Maintained by an independent third-party developer, not by Anthropic or an established SEO vendor: continuity depends on a single maintainer, even though external contributions do get merged.
- Some sub-skills (DataForSEO, Firecrawl) need paid third-party API keys to be fully useful; the core stays usable without them.
- Claude Code only: unlike the MCP servers in this list, it's not a model-agnostic tool usable with ChatGPT.
Frequently asked questions
Does claude-seo work with ChatGPT?
No, it's a Claude Code skill specifically, not an MCP portable to other agents.
Do I need to pay for third-party APIs to use it?
The core of the skill (technical audit, GEO, schema) works without any third-party key. Some optional extensions (DataForSEO, Firecrawl) require paid API keys for enriched data.
Who maintains this project?
An independent third-party developer (AgriciDaniel), not Anthropic. A contribution from this site on JSON-LD block truncation was in fact credited and merged in a more robust form.
Is it reliable enough for a paid client audit?
It's the tool used for this site's own audits, but like any third-party tool, a human review of its recommendations remains necessary before delivering them to a client as-is.
