Frequently Asked Questions

What is a robots.txt file? +

robots.txt is a file placed at the root of your website (example.com/robots.txt) that tells web crawlers which pages they can or cannot request. It follows the Robots Exclusion Protocol and is the first thing most crawlers fetch.

Does robots.txt prevent pages from being indexed? +

No — robots.txt prevents crawling, not indexing. If other pages link to a disallowed URL, Google can still index it without crawling it. To prevent indexing, use the noindex meta tag or X-Robots-Tag header.

How do I block AI training bots? +

Use the "Block AI Bots" preset. Common AI crawlers include: GPTBot (OpenAI), CCBot (Common Crawl), Google-Extended (Google AI), anthropic-ai (Anthropic), and ChatGPT-User. Add User-agent: BotName / Disallow: / for each.

What does "Disallow: /" mean? +

Disallow: / blocks all pages on the site for that user-agent. Disallow: /admin/ blocks only the /admin/ directory. Disallow: (empty) means allow everything. Allow: /public/ within a blocked section creates an exception.

Is robots.txt case-sensitive? +

Paths in robots.txt are case-sensitive on case-sensitive servers (most Linux servers). User-agent names are case-insensitive. So Disallow: /Admin/ and Disallow: /admin/ may be different paths.
