## What it does

The skill audits website accessibility for search bots run by OpenAI, Anthropic, Google, Apple, and Perplexity. It checks robots.txt directives, page meta tags, and HTTP headers to spot blocked bots. To do this, it relies on agent tools like `WebFetch`, `Bash`, `Read`, and `Grep`.

The tool distinguishes between search indexers and training scrapers. For instance, `OAI-SearchBot` powers live ChatGPT search results without collecting model training data, while `Google-Extended` controls Gemini training without affecting Google Search ranking. The skill produces an access map with recommendations for each bot.

An Originality.ai study from 2025 showed that over 35% of the top 1,000 websites block at least one AI crawler due to legacy rules. Overly aggressive configurations quietly eliminate your site from AI answers. Running this audit requires network connectivity and tool execution permissions in your agent.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add zubair-trabzada/geo-seo-claude --skill geo-crawlers -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/geo-crawlers/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/geo-crawlers/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add zubair-trabzada/geo-seo-claude --skill geo-crawlers -a codex
```

2. **Manually: put the files in place**

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add zubair-trabzada/geo-seo-claude --skill geo-crawlers -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/geo-crawlers/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install zubair-trabzada/geo-seo-claude geo-crawlers
```

2. **Manually: put the files in place**

gemini skills install https://github.com/zubair-trabzada/geo-seo-claude --path skills/geo-crawlers
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/geo-crawlers/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add zubair-trabzada/geo-seo-claude --skill geo-crawlers -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/zubair-trabzada/geo-seo-claude/tree/HEAD/skills/geo-crawlers/SKILL.md

## When to use it
- audit robots.txt directives for accidental AI bot blocks
- separate live AI search access from model training crawlers
- check HTTP headers and meta tags across target pages
- build an AI crawler visibility map for search engines

## Example prompts
- Check our robots.txt file and show whether GPTBot or ClaudeBot are blocked
- Generate a crawler access map for our domain and recommend changes for AI search
- Inspect the HTTP headers and meta tags on the homepage for OAI-SearchBot

# AI Crawler Access Analysis Skill

## Purpose

This skill analyzes a website's accessibility to AI crawlers -- the bots that AI companies use to discover, index, and train on web content. If AI crawlers are blocked, the site's content cannot appear in AI-generated responses regardless of its quality. Crawler access is the foundational technical requirement for GEO.

## Key Insight

As of early 2026, many websites inadvertently block AI crawlers through overly aggressive robots.txt rules, inherited from legacy SEO configurations. An Originality.ai 2025 study found that over 35% of the top 1,000 websites block at least one major AI crawler, and 5-10% block all AI crawlers. Blocking AI crawlers is the single fastest way to become invisible in AI-generated search results.

## Complete AI Crawler Reference

### Tier 1: Critical for AI Search Visibility (RECOMMEND: ALLOW)

These crawlers power the AI search products where users actively look for answers. Blocking them directly reduces your visibility in AI-generated responses.

#### GPTBot
- **Operator:** OpenAI
- **User-Agent:** `GPTBot`
- **Full User-Agent String:** `Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; GPTBot/1.2; +https://openai.com/gptbot)`
- **Purpose:** Fetches content for ChatGPT's web browsing, plugins, and search features. Content accessed by GPTBot may be used to improve OpenAI models.
- **Impact of Blocking:** Content will NOT appear in ChatGPT Search results or be accessible when users ask ChatGPT to browse the web. This is the highest-impact AI crawler to allow.
- **Recommendation:** **ALLOW** -- ChatGPT has 300M+ weekly active users as of 2025. Blocking GPTBot removes your content from one of the largest AI search surfaces.

#### OAI-SearchBot
- **Operator:** OpenAI
- **User-Agent:** `OAI-SearchBot`
- **Full User-Agent String:** `Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; OAI-SearchBot/1.0; +https://docs.openai.com/bots/overview)`
- **Purpose:** Specifically powers ChatGPT's search feature. Unlike GPTBot, content accessed by OAI-SearchBot is NOT used for model training -- only for live search results.
- **Impact of Blocking:** Content will not appear in ChatGPT's search results even if GPTBot is allowed.
- **Recommendation:** **ALLOW** -- This is a search-only crawler with no training implications. There is no strategic reason to block it.

#### ChatGPT-User
