Frequently asked questions

What is a robots.txt file?

A robots.txt file is a text file placed in the root of your website that tells web crawlers (like Googlebot) which pages or directories they can or cannot access. It helps manage crawl budget, protect private areas, and control AI training data usage.

Is this robots.txt generator free?

Yes, the tool is completely free with no sign-up required. All processing happens in your browser for maximum privacy.

Does it support blocking AI crawlers?

Yes. You can easily block major AI training bots such as GPTBot, ClaudeBot, CCBot, and others with a single toggle while keeping search engine crawlers allowed.

How do I use the generated robots.txt?

  1. Copy the generated content.
  2. Create a new file named exactly robots.txt (lowercase).
  3. Upload it to the root directory of your website (same level as your index.html or homepage).
  4. Test it using Google Search Console.

What are common mistakes this tool helps avoid?

It prevents syntax errors, missing User-agent directives, overly broad blocks that hurt SEO, and outdated rules. Real-time validation flags issues before you deploy.

Does it work well for WordPress sites?

Yes. The WordPress preset includes standard paths like /wp-admin/, /wp-includes/, and plugin directories while keeping public content crawlable.

Can I add custom rules?

Absolutely. Use the custom rules editor to add any valid directives, additional User-agents, or specific bot handling.

Is robots.txt enough to stop all unwanted crawlers?

Robots.txt is a request, not enforcement. Well-behaved crawlers (Google, Bing, major AI bots) respect it. Malicious bots may ignore it. Combine with server-side security for best protection.

How often should I update my robots.txt?

Review it after major site changes, new plugin installations, or when new AI crawlers emerge. Our tool makes quick updates easy.
