Pro Tips
- Place robots.txt at the root of your domain: https://yourdomain.com/robots.txt

- Test your robots.txt in Google Search Console's robots.txt Tester before deploying.

Frequently Asked Questions
Everything you need to know about Robots.txt Generator
What is robots.txt?
robots.txt is a text file placed at the root of a website that tells search engine crawlers which pages or sections they can or cannot access. It follows the Robots Exclusion Protocol.
Where should I put robots.txt?
Place the robots.txt file at the root of your website domain, accessible at https://yourdomain.com/robots.txt.
Can I block AI bots?
Yes. Use the Block AI Bots preset to automatically add rules blocking GPTBot (OpenAI), Google-Extended (Bard), CCBot (Common Crawl), and Anthropic AI from crawling your site.
Does Disallow prevent indexing?
No. Disallow blocks crawling but a page can still appear in search results if other pages link to it. Use the 'noindex' meta robots tag to prevent indexing.
What is crawl-delay?
Crawl-delay tells bots to wait a specified number of seconds between requests. This can prevent server overload from aggressive crawling. Note: Googlebot ignores crawl-delay.
Is my data safe?
Yes. All generation happens entirely in your browser. No data is sent to any server.
Is Robots.txt Generator free?
Yes! Robots.txt Generator is 100% free with no limits and no sign-up required. Create as many robots.txt files as you need.
What happens if I don't have a robots.txt?
Without a robots.txt file, search engines will crawl all publicly accessible pages on your site. This is fine for most sites, but you may want to block specific sections like admin panels, staging pages, or duplicate content.
