Quick Tips for Robots.txt Best Practices

  1. Test Before Deploying
    Always test your robots.txt in Google Search Console before going live
  2. Monitor AI Crawler Activity
    Track which AI bots visit your site and how often
  3. Update Regularly
    Review your robots.txt quarterly as new AI crawlers emerge
  4. Balance Access and Protection
    Allow AI crawlers for visibility while protecting sensitive content
  5. Consider Crawl Delay
    Set appropriate delays to manage server resources
  6. Include Your Sitemap
    Help crawlers discover all your important content

Pro tip: Combine your robots.txt with an llms.txt file for complete AI optimization. While robots.txt controls access, llms.txt provides context about your business for AI systems.

Why Control AI Crawler Access?

As AI becomes the primary way users discover information, controlling which AI systems can access your content is crucial. While allowing AI crawlers can increase your visibility in AI-generated responses, you may want to block certain crawlers to protect proprietary content, reduce server load, or maintain control over how your content is used in AI training.

Content Control

Decide which AI systems can use your content for training or real-time responses

AI Visibility

Allow helpful AI crawlers to increase your brand mentions in AI responses

Server Resources

Manage crawler traffic to optimize server performance and reduce costs

Frequently Asked Questions

What is a robots.txt file?

A robots.txt file is a text file placed in your website's root directory that tells web crawlers which pages or sections of your site they can or cannot access. It's part of the Robots Exclusion Protocol (REP) and is the first file crawlers check when visiting your website.

Why should I control AI crawler access?

Controlling AI crawler access is crucial for several reasons:

Learn more about why you might be invisible in AI search and how to fix it.

Which AI crawlers should I allow?

For maximum visibility, allow GPTBot (OpenAI), ClaudeBot (Anthropic), and PerplexityBot. B2B companies should focus on professional AI platforms like Claude and Perplexity. E-commerce sites should allow shopping-focused bots like Amazonbot and Google-Extended.

How does robots.txt affect my AI search visibility?

Your robots.txt file directly impacts how AI systems understand and recommend your business. Blocking AI crawlers means your content won't be included in AI training data or real-time responses. This is part of a larger strategy called Generative Engine Optimization (GEO), which focuses on optimizing for AI-powered search experiences rather than traditional search engines.

What's the difference between blocking Googlebot and Google-Extended?

Googlebot is Google's traditional search crawler that indexes content for Google Search. Google-Extended is specifically for Google's AI products like Gemini. You can block Google-Extended while still allowing Googlebot, which means your site will appear in Google Search but won't be used to train or power Google's AI models.

How often do AI crawlers visit websites?

According to our research, AI crawlers visit approximately 1 in 4 websites daily. The frequency depends on your site's authority, update frequency, and content type. Popular AI crawlers like GPTBot generate hundreds of millions of requests monthly. Learn more about AI crawler statistics and behavior.

Do I need both robots.txt and an llms.txt file?

While robots.txt controls crawler access, llms.txt provides structured information about your business specifically for AI systems. They serve different purposes: robots.txt is about access control, while llms.txt is about providing context. For optimal AI visibility, we recommend using both.

How can I test if my robots.txt is working correctly?

You can test your robots.txt file in several ways:

Be the brand AI recommends
