What is the Robots.txt Generator?
Generate a robots.txt file with disallow rules and your sitemap location. A robots.txt file tells search engine crawlers which areas of a site they may crawl and where to find your sitemap.

How to use the Robots.txt Generator
- Enter your user-agent, your disallow paths, your sitemap url.
- Tick the options you need: block ai training crawlers (gptbot, ccbot, google-extended).
- Results update automatically as you type; you can also press Calculate.
- Read the output: robots.txt.
- Use the 📊 chart to see the result visually, then copy or share it.
Formula and method
Where the Robots.txt Generator helps in real life
You launched a new website and need a clean robots.txt that points to your sitemap. The generator creates a valid file you can upload to the site root.
You want to keep crawlers out of an admin area and a staging folder. Adding disallow rules here keeps the syntax correct.
Common mistakes to avoid
- Blocking the whole site with “Disallow: /” by accident.
- Blocking CSS or JavaScript files that pages need.
- Using robots.txt to hide private information.
- Forgetting to include the sitemap line.
💡 Practical tip: robots.txt controls crawling, not indexing — use a noindex tag to keep a page out of search results.

Tips for better results
- Test the file in Google Search Console after uploading.
- Keep the rules short and simple.
- Add the full sitemap URL.
