robots.txt has been a web standard since 1994. In 2025, it has gained new importance as the primary tool for managing AI crawler access alongside traditional search engine access.

How robots.txt Works

The file lives at yourdomain.com/robots.txt and uses simple directives:

  • User-agent: Specifies which crawler the rules apply to
  • Disallow: Tells crawlers not to access specific paths
  • Allow: Permits access to specific paths (overrides Disallow)
  • Sitemap: Points crawlers to your XML sitemap

AI Crawler Management

With 52+ AI crawlers now active, managing access is important. The key AI crawlers to know:

  • GPTBot: OpenAI (ChatGPT)
  • ClaudeBot: Anthropic (Claude)
  • PerplexityBot: Perplexity AI
  • Bytespider: ByteDance
  • Google-Extended: Google AI training (separate from Googlebot)

Recommended Strategy

Allow AI search bots that drive discovery. Block AI training bots that only scrape content for model building. This maximizes your AI visibility while protecting content from unauthorized training use.

AppWT configures robots.txt as part of our technical SEO and AIVO services. We balance visibility with content protection. Learn about our technical SEO.
