Robots.txt Generator - Free Online Robots.txt File Generator

How to Use the Robots.txt Generator

1. Add rules — specify a user-agent (e.g., * for all crawlers, Googlebot for Google specifically), then add allow or disallow paths
2. Set crawl delay — optional delay in seconds to control how often crawlers hit your server
3. Add sitemap URL — link to your XML sitemap for better crawl discoverability
4. Review the output — see your robots.txt being built in real-time as you add rules
5. Copy the output — one-click copy of the complete robots.txt content, ready to upload to your site root

Perfect for SEO professionals, web developers, and site owners managing crawler access.

Features

• Multi-user-agent — create separate rules for different crawlers like Googlebot, Bingbot, and DuckDuckBot
• Allow/Disallow rules — granular path-level control over what crawlers can access
• Crawl delay — set crawl rate limits to prevent server overload
• Sitemap reference — link to your XML sitemap for better indexation

• No data sent — everything runs locally in your browser

Use Cases

• Blocking admin pages — prevent search engines from indexing wp-admin, /admin, or login pages

FAQ

Where do I upload my robots.txt file?

Upload it to the root of your domain — it must be accessible at yourdomain.com/robots.txt. Place it in your server’s document root or upload via your CMS settings.

Can I block a specific crawler with robots.txt?

Yes. Use the specific user-agent name for the crawler you want to target. For example, User-agent: ChatGPT-User to block OpenAI’s crawler, or User-agent: Googlebot to block Google specifically.

Does robots.txt prevent indexing?

No. Robots.txt controls crawling, not indexing. If a page is linked from elsewhere, Google may still index it without crawling. Use the noindex meta tag for true index blocking.

What happens if my robots.txt has a syntax error?

Most crawlers ignore malformed directives and may crawl everything. Always validate your robots.txt after making changes. The output from this generator is syntax-checked and ready to use.

Tips

• Place your robots.txt in the root directory — it won’t work from any other location
• Use Disallow: / for a user-agent to completely block that crawler from your entire site
• Always pair robots.txt with proper meta robots tags on pages you want to keep out of search results
• Test your robots.txt with Google’s robots.txt tester in Search Console after deployment
