robots.txt Directives Guide
User-agent: Targets specific web crawlers (e.g., Googlebot, Bingbot, or * for all bots). Multiple user-agent blocks can be defined for different crawler rules.
Disallow: Tells crawlers not to access specific paths or files on your site. Paths must start with /.
Allow: Overrides a Disallow directive for a specific path, useful when you want to allow access to a file within a disallowed directory.
Deploy the generated file to your site root directory (e.g., https://example.com/robots.txt) so search engine crawlers can discover it.
Frequently Asked Questions

Use Cases
The robots.txt Generator helps website owners and developers control how search engine crawlers access their site. A well-configured robots.txt file protects private directories, prevents duplicate content issues, and guides crawl budget toward the pages that matter most.
- Block crawlers from admin panels, staging environments, and internal APIs
- Prevent indexing of duplicate or thin-content pages
- Direct bots to your sitemap for faster discovery
- Reduce server load by excluding heavy asset directories
- Keep development sites out of search results during builds
How-To
Generate a robots.txt file in three steps. Open the tool, enter your domain, and choose which paths to allow or disallow. Download the file and upload it to your site's root directory so crawlers can find it at yourdomain.com/robots.txt.
- Enter your website domain in the input field
- Select paths to disallow, such as /admin/ or /private/
- Optionally add your sitemap URL
- Click Generate and download the robots.txt file
- Upload the file to the root of your web server
- Verify access at yourdomain.com/robots.txt
A robots.txt file is a plain text file that tells search engine bots which parts of your site they can crawl. It lives in your root folder and is the first file reputable crawlers check before indexing your content. Proper syntax matters — a single typo can accidentally block your entire site from search results.
Use the Disallow directive to keep bots out of specific folders and the Allow directive to carve out exceptions. Combine directives with user-agent rules to target individual crawlers like Googlebot or Bingbot. Always reference your XML sitemap so search engines discover new pages quickly.
Benefits include better crawl efficiency, protected staging content, and clearer signals to search engines about which pages deserve visibility. A clean robots.txt setup supports technical SEO health across the entire site.
Common mistakes include blocking CSS and JavaScript files, which can break rendering, and using robots.txt to hide sensitive data — it is not a security measure. Pair this tool with meta robots tags and canonical URLs for a complete SEO strategy that keeps your site visible and well-indexed.
