Robots.txt Generator
Build your robots.txt visually — select user-agents, add Allow/Disallow rules, set Sitemap and Crawl-delay, then copy or download.
What Is a Robots.txt Generator?
A robots.txt file tells search engine crawlers which pages or sections of your website they can or cannot access. This generator lets you build a properly formatted robots.txt file through a visual interface — no manual editing needed. Select user-agents like Googlebot, Bingbot, or GPTBot, add Allow/Disallow rules for specific paths, include your Sitemap URL, and set an optional Crawl-delay. The file is generated instantly in your browser with a live preview.
How to Use the Robots.txt Generator
- Select a User-Agent — Choose from common bots (Googlebot, Bingbot, GPTBot, etc.) or enter a custom name
- Add Rules — Set the rule type (Allow or Disallow), enter the path (e.g., /admin/), and click Add
- Set Sitemap — Enter your sitemap URL (e.g., https://example.com/sitemap.xml)
- Enable Crawl-delay — Optionally set a delay in seconds between crawler requests
- Preview & Export — See the generated file in real time, then copy or download it

FAQ
What is a robots.txt file?
A robots.txt file is a plain text file placed at the root of your website (e.g., example.com/robots.txt) that tells web crawlers which URLs they are allowed or not allowed to access. It follows the Robots Exclusion Protocol standard.
How do I block AI crawlers like GPTBot?
Select GPTBot (or ChatGPT-User, ClaudeBot) from the User-Agent dropdown, add a Disallow rule for '/', and the generated robots.txt will instruct those bots not to crawl any page on your site.
Where do I upload the robots.txt file?
Upload the robots.txt file to the root directory of your website so it is accessible at https://yourdomain.com/robots.txt. Most web hosts allow this via FTP, cPanel File Manager, or your CMS settings.
Does robots.txt guarantee pages won't be indexed?
No. Robots.txt is a directive, not an enforcement mechanism. Well-behaved crawlers respect it, but malicious bots may ignore it. For guaranteed de-indexing, use the noindex meta tag or X-Robots-Tag HTTP header.
What does Crawl-delay do?
Crawl-delay tells a crawler to wait a specified number of seconds between requests. This can reduce server load from aggressive crawlers. Note that Googlebot ignores Crawl-delay — use Google Search Console to set crawl rate for Google.
