Claude SEO - Setup Guide

Source: skills.sh (31 skills, ~160,000 combined installs) GitHub: AgriciDaniel/claude-seo (16,628⭐, 2,436 forks, MIT, very active) Category: Marketing / SEO First Seen: Jul 23, 2026 sweep (rejected as "Claude Code-specific"); overturned Sep 9, 2026 - 31 skills are now on skills.sh in open Agent Skills format with broad cross-agent adoption Quality Tier: 🟡 Production (Gen Agent Trust Hub Pass / Socket Pass / Snyk Warn - W011 third-party content exposure, inherent to SEO workflows)

A universal SEO suite: 25 core skills + 6 extension skills, with the flagship seo-audit crawling up to 500 pages and delegating to up to 15 parallel specialist sub-agents. Covers technical SEO, E-E-A-T content quality, Schema.org, AI-search optimization (GEO/AEO), backlinks, local SEO, e-commerce, international SEO, and Google APIs - every audit output is a prioritized action plan with falsifiable recommendations grounded in Google primary-source guidance.

Installation

The skills themselves are open Agent Skills format and install via skills.sh:

npx skills add agricidaniel/claude-seo

For Hermes Agent, copy from a clone:

git clone --depth 1 https://github.com/AgriciDaniel/claude-seo.git
cp -r claude-seo/skills/* ~/.hermes/skills/

Heavy-tool dependency: several skills (e.g. seo-audit) call claude-seo run render_page.py - a CLI installed by the repo's setup script (isolated Python env + Playwright Chromium). Install it once per machine:

bash claude-seo/install.sh # from the clone; review before running
claude-seo doctor # verify the toolchain

(Claude Code users can instead use the plugin path: /plugin marketplace add AgriciDaniel/claude-seo → /plugin install claude-seo@agricidaniel-claude-seo → /seo setup. That path is Claude-Code-specific; the skills.sh + manual paths above are not.)

Prerequisites

Requirement Details
Hermes Agent Skills directory support (~/.hermes/skills/)
Python 3 + Playwright Installed by install.sh for the render tooling (headless Chromium for page rendering/SPA capture)
Node.js 18+ For the npx skills path
Optional API keys Extension skills: DataForSEO, Firecrawl, Ahrefs, Bing Webmaster, SE Ranking, Unlighthouse, Profound, Banana (image gen) - each extension is optional

  2. "Audit corpusiq.io" → seo-audit crawls and produces a prioritized action plan
  3. "Check our AI-search visibility" → seo-geo for citability/llms.txt/AEO
  4. "Write a content brief for [keyword]" → seo-content-brief

CorpusIQ Use Cases

Use Case How
Docs SEO/AEO/GEO program CorpusIQ's docs SEO pass (frontmatter, llms.txt, JSON-LD) gets automated audit + fix loops via seo-audit, seo-geo, seo-schema
Competitive SEO intelligence seo-competitor-pages + seo-drift for tracking competitor ranking moves - feeds the competitive-attack playbook
Content briefs seo-content-brief for SERP-grounded briefs before any blog/docs page is written
Technical SEO hygiene seo-technical + seo-sitemap as a recurring site-health check for corpusiq.io and client domains

Limitations / Verification

  • Snyk Warn (W011, MEDIUM): skills ingest arbitrary third-party URLs (audited pages, SERPs) - indirect prompt-injection surface. Standard mitigation: treat page content as data, never as instructions; the skill's own workflow already separates analysis from actions
  • Distribution is Claude-Code-first upstream (plugin marketplace, /seo slash commands) - but the SKILL.md layer is platform-agnostic and that is what skills.sh installs
  • Extension skills are low-install on skills.sh (58 - 69) but functional; they just aren't widely adopted yet
