Process

Step 1: Check AI Crawler Access

Read robots.txt and check if these crawlers are allowed:

Crawler	Owner	Purpose	Recommendation
GPTBot	OpenAI	ChatGPT Search	✅ Allow
OAI-SearchBot	OpenAI	OpenAI Search	✅ Allow
ChatGPT-User	OpenAI	ChatGPT Browsing	✅ Allow
ClaudeBot	Anthropic	Claude Search	✅ Allow
PerplexityBot	Perplexity	Perplexity AI	✅ Allow
CCBot	Common Crawl	Training data	⚠️ Optional block
anthropic-ai	Anthropic	Claude Training	⚠️ Optional block
Bytespider	ByteDance	TikTok AI	⚠️ Optional block

Problem Examples:

❌ GPTBot blocked → ChatGPT can't cite your content
❌ PerplexityBot blocked → Perplexity can't cite you

Fix Output:

# robots.txt modification suggestion
User-agent: GPTBot
Allow: /

User-agent: ClaudeBot
Allow: /

User-agent: PerplexityBot
Allow: /

Step 2: Check llms.txt

Check if /llms.txt exists:

Status	Description
✅ Exists and complete	Has title, description, key page list
⚠️ Exists but incomplete	Missing key information
❌ Does not exist	Needs creation

Fix Output (generate llms.txt):

# [Website Name]
> [One-line description]

## Core Pages
- [Homepage](https://example.com/): Website homepage
- [Products](https://example.com/products): Product list
- [About Us](https://example.com/about): Company introduction

## Key Information
- Founded in XXXX
- Serving XXX customers
- Main business: XXX

Step 3: Check Server-Side Rendering

AI crawlers don't execute JavaScript - key content must be directly visible in HTML.

Check method:

1. Access page with JavaScript disabled
2. Check if key content is visible

Status	Description
✅ SSR	Key content in HTML
❌ CSR	Key content requires JS to load

Problem Examples:

❌ Product descriptions only appear after JS rendering
❌ Article body depends on React hydration

Fix Recommendations:

• Use SSR/SSG frameworks (Next.js, Nuxt, Astro)
• Pre-render key pages
• Ensure <noscript> has content

Step 4: Platform-Specific Check

Platform	Technical Requirements
Google AI Overviews	Traditional SEO basics + Schema
ChatGPT	GPTBot access + llms.txt
Perplexity	PerplexityBot access
Bing Copilot	Bing indexing + IndexNow
