What 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.

# Example robots.txt

User-agent: *
Disallow: /wp-admin/
Allow: /wp-admin/admin-ajax.php

# Block AI Training Crawlers
User-agent: GPTBot
Disallow: /

User-agent: ClaudeBot
Disallow: /

Sitemap: https://example.com/sitemap.xml

Everything You Need in a Robots.txt Generator

Our free robots.txt creator goes beyond basic generators. Here is what sets it apart.





Block AI Crawlers with One Click

Over 14 AI companies now send crawlers to scrape your website for training data. Our robots.txt generator is the first to include a dedicated AI Crawler Control Center.

  • Block GPTBot, ClaudeBot, CCBot, and 11 more
  • Separate training crawlers from search crawlers
  • “Block All AI” and “Block Training Only” quick actions
  • Toggle individual bots on or off with switches
  • See each crawler’s company and purpose

Manage 14 AI crawlers across training and search categories. No other robots.txt generator offers this level of control.

Start with a Ready-Made Template

Do not start from scratch. Pick a template that matches your site type and customize from there.

  • WordPress Default: blocks wp-admin, allows admin-ajax
  • E-commerce: blocks cart, checkout, and account pages
  • Block All AI Crawlers: WordPress defaults plus all AI bots
  • Search Engines Only: whitelist Google, Bing, and others
  • Maximum Privacy: blocks all crawlers entirely
  • Starter: allows everything with a sitemap entry

Click a template, customize the rules, and download your file. It takes less than 30 seconds.

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

Most generators force you to start from zero. Ours lets you build on what you already have.

Test Your Rules Before Deploying

Enter any URL and choose a user-agent to check whether the page would be allowed or blocked by your generated robots.txt.

  • Test any URL against any user-agent in your rules
  • Shows which specific rule matched
  • Supports wildcard pattern matching
  • Verify before you upload to your server

Confidence before deployment. Test your rules right in the tool, no guesswork needed.

Frequently Asked Questions

What is a robots.txt generator?
A robots.txt generator is a free online tool that creates a robots.txt file for your website without requiring you to write code. You configure rules visually, and the tool outputs the properly formatted text file you upload to your server.
Where do I upload my robots.txt file?
Upload the file to the root directory of your website so it is accessible at https://yourdomain.com/robots.txt. For WordPress, you can upload via FTP, cPanel File Manager, or use DefiniteSEO WordPress SEO Plugin that includes a built-in robots.txt editor.
Does blocking a page with robots.txt remove it from Google?
No. Disallow in robots.txt prevents crawling, but Google can still index the URL if other pages link to it. To fully remove a page from search results, use a noindex meta tag or the X-Robots-Tag HTTP header.
Can I block AI crawlers like ChatGPT and Claude?
Yes. Our robots.txt generator includes a dedicated AI Crawler Control Center with 14 known AI crawlers. Toggle them on to add User-agent: GPTBot / Disallow: / directives. This blocks AI companies from using your content for training while keeping search engines unaffected.
Does Google honor the crawl-delay directive?
No. Google ignores the crawl-delay directive entirely. To control Google’s crawl rate, use Google Search Console. However, Bing, Yandex, and some other crawlers do respect crawl-delay.
What is the difference between Allow and Disallow?
Disallow: /path/ blocks crawlers from accessing everything under that path. Allow: /path/file.php creates an exception, permitting access to a specific URL even if its parent directory is blocked. When both match, the more specific (longer) rule wins.
Can I use wildcards in robots.txt?
Yes. Google and Bing support * to match any sequence of characters and $ to match the end of a URL. For example, Disallow: /*.pdf$ blocks all PDF files. Not all crawlers support wildcards, but major search engines do.
Is this robots.txt generator free?
Yes. This tool is 100% free with no signup, no login, and no limits. Generate, import, test, and download as many robots.txt files as you need.
