Robots.txt for AI
Using the robots.txt file to control which AI crawlers can access your website content, directly affecting your AI visibility.
How Robots.txt Affects AI Visibility
Your robots.txt file determines which AI crawlers can access your website. If you block AI crawlers, platforms like ChatGPT and Claude cannot access your current content and will rely on older or third-party information. Allowing AI crawlers ensures these platforms have accurate, up-to-date information about your business.
AI Crawler User Agents
Key user agents to configure: GPTBot (OpenAI/ChatGPT), ChatGPT-User (ChatGPT browsing), ClaudeBot (Anthropic/Claude), Anthropic-AI (Claude training), PerplexityBot (Perplexity), Google-Extended (Gemini), Meta-ExternalAgent (Meta AI), cohere-ai (Cohere), Bytespider (ByteDance AI), YouBot (You.com).
Recommended Configuration
For maximum AI visibility, explicitly allow all major AI crawlers in your robots.txt. You can selectively block specific crawlers if needed, but blocking all AI crawlers will significantly reduce your AI visibility. Consider allowing crawlers to access your most important content while blocking admin or private sections.
Monitoring AI Crawler Activity
Check your server logs to see which AI crawlers visit your site, how often they crawl, and which pages they access. This data helps you understand which AI platforms are indexing your content and identify any access issues.
