Common Use Cases for robots.txt Generator
New Website Launch
Generate a robots.txt file before launching a new website to control which pages search engines can crawl. Use our robots.txt generator to block admin panels, staging areas, and private directories from day one.
SEO Crawl Budget Optimization
Large websites use robots.txt to prevent search engines from wasting crawl budget on low-value pages like faceted navigation, session parameters, and duplicate content. Generate targeted Disallow rules for each bot.
Blocking AI Training Crawlers
Block AI training bots like GPTBot (OpenAI) and Claude-Web (Anthropic) from crawling your content. Our robots.txt generator includes presets for all major AI crawlers so you can opt out with one click.
Staging & Development Environments
Generate a robots.txt that blocks all crawlers for staging and development environments. Use the wildcard user-agent (*) with Disallow: / to prevent accidental indexing of test content.
E-Commerce & CMS Sites
E-commerce sites use robots.txt to block cart pages, checkout flows, search result pages, and user account areas. Generate per-bot rules to allow Google Shopping while blocking other crawlers from sensitive paths.
Sitemap Submission
Include your sitemap.xml URL in robots.txt to help search engines discover all your pages. Our robots.txt generator lets you add multiple sitemap URLs and validates the format before generating the file.
Understanding robots.txt
What is a robots.txt Generator?
A robots.txt generator is a tool that creates a valid robots.txt file from a visual interface, eliminating the need to write the file manually. The robots.txt file is a plain text file placed at the root of your website that tells search engine crawlers which pages or directories they are allowed or not allowed to access. Our robots.txt generator supports all standard directives — User-agent, Allow, Disallow, Crawl-delay, Sitemap, and Host — and includes presets for 14 common bots including Googlebot, Bingbot, and AI training crawlers like GPTBot and Claude-Web. All generation runs locally in your browser with no data sent to any server.
How Our robots.txt Generator Works
- 1. Configure User-Agent Groups: Select a bot from the preset list (Googlebot, Bingbot, GPTBot, etc.) or enter a custom user-agent. Add multiple groups to set different rules for different crawlers.
- 2. Add Allow and Disallow Rules: Add Allow and Disallow rules for each user-agent group. Enter the path to allow or block (e.g. /admin/). Add a Crawl-delay value to throttle aggressive crawlers.
- 3. Generate, Copy, and Deploy: Click Generate robots.txt to produce the formatted file. Copy it to your clipboard or download it directly. Upload the file to the root of your website at yourdomain.com/robots.txt.
robots.txt Directives Explained
- User-agent: Specifies which crawler the following rules apply to. Use * (wildcard) to target all bots, or specify a named bot like Googlebot. Each user-agent block applies until the next User-agent directive.
- Disallow: Tells the specified crawler not to access the given path. An empty Disallow value means the crawler can access all pages. Use /admin/ to block a directory, or /page.html to block a specific page.
- Allow: Explicitly permits access to a path that would otherwise be blocked by a Disallow rule. Allow takes precedence over Disallow when both match the same path (longest-match rule applies).
- Crawl-delay: Requests that the crawler wait the specified number of seconds between requests. Not supported by Googlebot (use Google Search Console instead), but respected by Bingbot, Yandex, and others.
- Sitemap: Specifies the full URL of your XML sitemap. This helps search engines discover all your pages. You can include multiple Sitemap directives. The Sitemap directive is not user-agent specific.
- Host: Specifies the preferred domain for your website. Only supported by Yandex — not recognized by Google or Bing. Use it if you have multiple domain variants and want Yandex to prefer one.
Important Notes About robots.txt
robots.txt is a request, not a technical barrier — well-behaved crawlers respect it, but malicious bots may ignore it. Disallowing a page in robots.txt does not remove it from search results if other pages link to it; use a noindex meta tag for that. Google does not support Crawl-delay — use Google Search Console to set crawl rate instead. Always validate your robots.txt after generating it using our Robots.txt Validator tool to catch syntax errors before deploying.

Frequently Asked Questions About robots.txt Generator
A robots.txt generator is a tool that creates a valid robots.txt file from a visual interface. Our robots.txt generator supports all standard directives — User-agent, Allow, Disallow, Crawl-delay, Sitemap, and Host — with 14 bot presets including Googlebot, Bingbot, and AI crawlers. All generation runs locally in your browser.
Upload the robots.txt file to the root directory of your website so it is accessible at https://yourdomain.com/robots.txt. For most web servers, this means placing it in the public_html, www, or root folder. The file must be at the exact root path — subdirectory robots.txt files are not recognized by search engines.
Add a user-agent group with User-agent: * and a single Disallow: / rule. This tells all crawlers not to access any page on your site. This is commonly used for staging environments, private intranets, and sites under construction.
Select GPTBot or Claude-Web from the user-agent preset dropdown and add a Disallow: / rule. You can add separate groups for each AI crawler. Our robots.txt generator includes presets for GPTBot (OpenAI), Claude-Web (Anthropic), and CCBot (Common Crawl).
No. Google does not support the Crawl-delay directive in robots.txt. To control Googlebot's crawl rate, use the Crawl Rate settings in Google Search Console. Crawl-delay is respected by Bingbot, Yandex, and some other crawlers.
Yes! Add multiple user-agent groups — one for each bot. Each group has its own set of Allow/Disallow rules and Crawl-delay. For example, you can allow Googlebot to crawl everything while blocking GPTBot from all pages.
Yes! Our robots.txt generator is 100% free with no signup, no ads, and no usage limits. Generate and download robots.txt files as many times as you need — completely free, forever.
Absolutely. All robots.txt generation happens locally in your browser using JavaScript. Your domain, paths, and configuration are never sent to any server, ensuring complete privacy every time you use our robots.txt generator online.
No. Disallowing a page in robots.txt prevents crawlers from accessing it, but if other pages link to it, search engines may still index it and show it in results without content. To prevent a page from appearing in search results, use a noindex meta tag or HTTP header instead.
