SEO: Universal SEO Analysis Skill

Invocation: /seo $1 $2 where $1 is the command and $2 is the URL or argument.

Runtime: Run bundled Python tools through "${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run <script.py>. That is the single canonical form used by every skill and agent. Claude Code expands ${CLAUDE_PLUGIN_ROOT} to the installed plugin directory, so the launcher is found without any PATH entry; the repository ships no top-level bin/ directory because hosted marketplaces reject one. Repository users run ./scripts/claude-seo; manual installers rewrite the canonical form to "$HOME/.claude/skills/seo/scripts/claude-seo". Never invoke bundled scripts with a bare Python interpreter.

Comprehensive SEO analysis across all industries (SaaS, local services, e-commerce, publishers, agencies). Orchestrates 25 sub-skills (22 core + 1 framework integration + 2 extension mirrors) and 19 sub-agents. A separate optional Firecrawl extension is also installable (see "Optional Extensions" below).
