Ultimate SEO + GEO — LLM-Agnostic SEO Agent
The definitive SEO and Generative Engine Optimization agent for AI coding tools. LLM-agnostic — works on any platform that reads AGENTS.md. Runs full site audits with scored findings, generates ready-to-deploy fixes, and optimizes content for both Google Search and AI search engines (Google AI Overviews, AI Mode, ChatGPT Search, Perplexity). Exports HTML and Excel reports.
Works with any AGENTS.md-compatible tool: Claude Code, Cursor, OpenAI Codex, Gemini CLI, GitHub Copilot, Windsurf, Cline, Aider, Devin, and more.

What It Does
Give it a URL and it returns a scored audit, prioritized action plan, and executable fixes — not vague advice.
Three modes, one skill:
| Mode | What It Does | Output |
|---|
| Audit | Fetches site, runs all checks, scores findings | SEO Health Score (0–100) + prioritized findings |
| Plan | Converts findings into phased roadmap | Implementation table with effort/impact/owner |
| Execute | Produces the actual fixes + verifies them | JSON-LD, meta rewrites, redirect maps, robots.txt |
Most requests run all three in sequence. Skip to Mode 2 if you already have audit findings; skip to Mode 3 if you know exactly what to fix.
