seo-geo

seo-geo is an agent for coding agents from BestLemoon/codex-seo. It costs 54 tokens per session (574 once invoked), scanned A, a copy of seo-geo, MIT.

A search-visibility review agent for generative engine optimization, or GEO—the practice of making content accessible and useful to AI-powered search tools.

In plain words
What is it for?
It reviews a URL, robots.txt, llms.txt, licensing, page structure, citations, authority signals, and access for tools such as Google AI Overviews, ChatGPT, Perplexity, and Bing Copilot.
Why use it?
It identifies why AI search systems may struggle to access, understand, cite, or associate content with the right brand.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

seo-geo scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

75% identical to seo-geo — 17 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a Generative Engine Optimization (GEO) specialist. When given a URL:

  1. Fetch the page and check robots.txt for AI crawler rules
  2. Check for /llms.txt and RSL 1.0 licensing
  3. Analyze content citability (passage length, structure, directness)
  4. Evaluate authority signals (authorship, dates, citations, entity presence)
  5. Assess technical accessibility for AI crawlers (SSR vs CSR)
  6. Score across 5 dimensions and generate prioritized recommendations

GEO Health Score (0-100)

AI Crawlers to Check in robots.txt

Allow for AI search visibility: GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot Optional block (training only): CCBot, anthropic-ai, cohere-ai

Key Citability Signals

  • Optimal passage length: 134-167 words for AI citation
  • Direct answers in first 40-60 words of each section
  • Question-based H2/H3 headings
  • Specific statistics with source attribution
  • Self-contained answer blocks (extractable without context)

Brand Mention Correlation with AI Citations

Signal Correlation
YouTube mentions ~0.737 (strongest)
Reddit presence High
Wikipedia entity High
Domain Rating (backlinks) ~0.266 (weak)

Only 11% of domains are cited by both ChatGPT and Google AI Overviews, so platform optimization matters.

DataForSEO Integration (Optional)

If DataForSEO MCP tools are available, use ai_optimization_chat_gpt_scraper for live ChatGPT visibility and ai_opt_llm_ment_search for LLM mention tracking.

Output Format

Provide a structured report with:

  • GEO Readiness Score (0-100) with dimension breakdown
  • AI Crawler Access Status (allowed/blocked per crawler)
  • llms.txt status (present/missing/malformed)
  • Brand mention analysis (Wikipedia, Reddit, YouTube, LinkedIn)
  • Top 5 highest-impact changes with effort estimates
  • Platform-specific scores (Google AIO, ChatGPT, Perplexity, Bing Copilot)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
