🤖 Robots.txt Generator
Last updated:
Generate robots.txt files. Allow/disallow crawlers, set crawl-delay and sitemap URL. Free, instant.
Build a robots.txt file by selecting from common directives — allow or block all crawlers, target specific bots like Googlebot or AI scrapers, protect private directories, and include your sitemap URL. The generated file appears instantly and is ready to copy and deploy to your website's root. All configuration runs in your browser.
Advanced rules (custom Allow / Disallow)
📋 When to Use the Robots.txt Generator
Write a correct robots.txt when launching a site, blocking a staging path, or pointing crawlers at your sitemap. The form keeps directive syntax straight — User-agent, Allow, Disallow, Sitemap — so you don't accidentally deny your whole site, a mistake that is surprisingly easy to make when editing by hand.
⚙️ How the Robots.txt Generator Works
The Robots.txt Generator runs entirely in your browser using client-side JavaScript. When you interact with the tool — entering text, adjusting settings, or clicking Generate — the browser processes your input using built-in algorithms and renders the output in real time. No data is ever sent to a server. For CDN-loaded libraries (like QR code generation), the library code downloads once to your browser and then runs locally — your data stays on your device throughout the entire process.
How to Use the Robots.txt Generator
1. Set your sitemap URL (optional). Enter your full sitemap URL (e.g., https://yoursite.com/sitemap.xml) to help search engines discover your content. This adds a Sitemap: directive to the generated file.
2. Choose your crawling rules. Use the checkboxes to configure access: allow all crawlers (default), block Googlebot specifically, block AI crawlers (GPTBot, CCBot), or block the /admin directory. You can combine multiple options.
3. Review the generated robots.txt. The output panel shows your complete robots.txt file in real time as you toggle options. Copy it directly or use it as a starting template.
4. Upload to your site. Save the generated content as robots.txt and upload it to your website's root directory (e.g., https://yoursite.com/robots.txt). Search engines will respect it on their next crawl.
Frequently Asked Questions
What is a robots.txt file?
It's a text file placed in your website's root directory that tells search engine crawlers which pages or sections they should and should not access. It's part of the Robots Exclusion Protocol (REP), a standard honored by all major search engines.
Does robots.txt block pages from being indexed?
No. robots.txt controls crawling, not indexing. A page blocked in robots.txt won't be crawled, but it could still appear in search results if other pages link to it. To prevent indexing, use a noindex meta tag instead.
What are AI crawlers and should I block them?
AI crawlers like GPTBot (OpenAI) and CCBot (Common Crawl) scrape web content to train AI models. Blocking them prevents your content from being used in AI training datasets without your consent. Many site owners choose to block them.
How do I verify my robots.txt is working?
After uploading, use Google Search Console's robots.txt Tester tool, or simply visit https://yoursite.com/robots.txt in your browser. You can also check individual URLs in Search Console's URL Inspection tool.
