Explore DefiniteSEO SuiteWhat Is a robots.txt File?
A robots.txt file is a plain text file placed at the root of your website that tells search engine crawlers and AI bots which pages they can and cannot access. Every major search engine, including Google, Bing, and DuckDuckGo, reads this file before crawling your site.
Without a robots.txt file, all crawlers have unrestricted access to every page on your site. With one, you control what gets crawled, protect private directories, manage your crawl budget, and now, block AI training crawlers from scraping your content.
Our free robots.txt generator creates this file for you visually, so you never have to write a single line of code. For a deeper understanding of how robots.txt works and its role in technical SEO, read our complete robots.txt guide for technical SEO.

Avoid Common Mistakes Automatically
Our robots.txt maker watches your rules in real time and warns you before you break something.
- Warns if you block all crawlers from your entire site
- Detects when you block CSS or JS files
- Reminds you that Disallow does not mean noindex
- Flags crawl-delay (Google ignores it)
- Suggests allowing admin-ajax.php when blocking wp-admin
Real-time warnings prevent SEO mistakes before they happen. No more accidentally deindexing your site.
Import and Edit Your Existing robots.txt
Already have a robots.txt file? Paste it or fetch it from your domain. Our tool parses it into a visual editor so you can modify rules without touching code.
- Paste your existing robots.txt to edit visually
- Fetch from any domain automatically
- AI crawlers are detected and shown as toggles
- Add new rules on top of your existing ones

- Test any URL against any user-agent in your rules
- Shows which specific rule matched
