Create a Robots.txt Generator File Online to Guide Search Engine Crawlers

The Robots.txt Generator helps you create a robots.txt file for your website without writing the rules manually. Set which parts of your site search engine crawlers can access or skip, then generate the file for your website.

How to Use

Managing how search engines and web crawlers access your website becomes simple with the Robots.txt Generator. Follow these steps to build your custom text file:

1. Select a configuration from the Start from a preset dropdown, or keep the default custom layout.
2. Choose a specific bot from the User-agent dropdown in your rule group, or type a custom name if you selected the custom option.
3. Fill in the Crawl-delay in seconds (optional) field if you want to request a pause between bot visits.
4. Enter any restricted URLs in the Disallow paths (one per line) text area, making sure each entry starts with a slash or an asterisk.
5. Specify any exceptions in the Allow paths (one per line) text area.
6. Click the + Add Rule Group button if you need to set rules for additional crawlers, up to a maximum of twenty groups.
7. Enter your absolute URLs in the Sitemap URLs (one per line, optional) section to include your sitemaps.
8. Click the Generate robots.txt button to build the file, then use the Copy or Download robots.txt buttons to save your text.

Features / Benefits

Pre-built presets let you quickly apply standard configurations, such as blocking all traffic or allowing standard WordPress rules without manual typing. The tool handles multiple rule groups so you can apply distinct directives to specific bots rather than treating every crawler identically. You can pick from a built-in list of common web bots or type any custom crawler name into the text input.

After you click the Generate robots.txt button, a warning appears if your settings block all crawlers from your entire site, helping you avoid accidental de-indexing. The Robots.txt Generator also lets you add multiple sitemap links, so crawlers can find your sitemaps directly from the robots.txt file. The file is generated in your browser with JavaScript, so you can build and export it without page reloads.

Detailed Information

A standard robots.txt file provides instructions to automated bots visiting your web domain, directing them on which folders they may read or skip. The Robots.txt Generator allows up to twenty separate rule groups per file to accommodate complex site hierarchies. Path entries must begin with a forward slash or an asterisk and cannot contain spaces, ensuring valid syntax that crawlers can parse correctly.

The optional crawl delay accepts whole numbers ranging from zero to 3600 seconds, though major engines like Google ignore this specific directive. Sitemap URLs must be absolute links starting with standard protocols. When a rule group contains no allow or disallow paths, the output automatically generates an empty disallow line to signify open access.

Common Uses / Examples

Setting up a new WordPress site requires letting administrative scripts run while shielding sensitive backend folders.

• Input: Select the standard WordPress preset from the dropdown menu and click generate.
• Result: The tool outputs a configuration that allows the admin ajax script while disallowing the rest of the WordPress administrative directory.

Protecting a site from automated AI scrapers involves targeting specific harvesting bots.

• Input: Choose the option to block common AI training bots and review the generated output.
• Result: The text creates individual blocks that disallow GPTBot, ClaudeBot, and other harvesters while leaving general search crawlers unrestricted.

Pointing search engines directly to your site maps helps indexation.

• Input: Paste an absolute sitemap link into the sitemap text area and click generate.
• Result: The output appends a clean sitemap line at the bottom of your file for search engines to follow. Using a Robots.txt Generator simplifies these everyday web maintenance tasks.

Tips / Best Practices

Always inspect the read-only output box carefully after generating your text to ensure every path starts with the correct character before you save the file.

Use the remove button on individual rule groups if you added extra sections by accident, keeping your file clean and easy to read. Place the downloaded file directly into the root directory of your domain so web crawlers can locate it immediately upon visiting.

Remember that custom bot names must only contain alphanumeric characters, periods, dashes, underscores, or asterisks to prevent syntax errors.

Privacy & Security

The robots.txt file is generated in your browser using JavaScript. The tool’s code does not send your entered paths, custom bot names, or sitemap URLs to any server, and it does not save them in cookies or local storage. When you click Copy or Download, the text is placed on your clipboard or saved as a file on your device, so handle it like any other file. Reloading the page clears the form.

Conclusion

Building a proper robots.txt file is straightforward when using the Robots.txt Generator. A correct configuration tells well-behaved crawlers which areas to skip and where your sitemaps are, but it is not a security measure, so private content should always be protected by other means.
