Robots.txt Generator
Generate a robots.txt file with custom allow/disallow rules for Googlebot, Bingbot, and more. Preview, validate, and download your robots.txt. Free tool.
What is a Robots.txt Generator?
The Robots.txt Generator creates a complete, valid robots.txt file through a form interface. Define crawl rules for Googlebot, Bingbot, AdsBot, GPTBot, Claude-Web, CCBot, and any other user-agent, set allow and disallow directives for specific URL patterns, reference your XML sitemap, and optionally configure a crawl delay. The tool outputs the correctly formatted robots.txt content ready to copy and upload to your domain root.
When Should You Use Robots.txt Generator?
Use this when setting up a new website, when the existing robots.txt needs a significant revision, or when you need to add directives for AI crawlers — GPTBot (OpenAI), Claude-Web (Anthropic), CCBot (Common Crawl) — that were not considered when the file was originally written. A well-configured robots.txt prevents crawl budget waste on low-value URLs such as admin pages, checkout flows, and parameter-based duplicates, while keeping important pages accessible to search engines.
How to Read Robots.txt Generator Results
Review every disallow rule carefully before deploying. A rule like Disallow: / with no user-agent scoping blocks every crawler from your entire site. A rule like Disallow: /admin/ blocks only URLs beginning with that path. After generating and uploading the file, test specific URLs using the Robots.txt Tester to confirm individual rules behave exactly as expected — particularly any rules using wildcard patterns, which can match more URLs than intended.
What Should You Know Before Using Robots.txt Generator?
Do not block CSS and JavaScript files in your robots.txt. Googlebot needs to render your pages to understand them, and blocking these resources prevents it from seeing your pages as users do — which can cause Google to misrepresent their content or drop them from indexing. Always include your XML sitemap URL at the end of the file. Block /wp-admin/, /checkout/, /cart/, /account/, and any other paths that generate session-specific URL variants or expose internal functionality with no indexing value.
Frequently Asked Questions
What is a robots.txt file?
Robots.txt is a plain-text file placed at the root of your website (yourdomain.com/robots.txt) that tells search engine crawlers which URLs they are and are not allowed to access. It is part of the Robots Exclusion Protocol and is checked by well-behaved crawlers before they visit any other page on your site.
How do I block a specific page from Google in robots.txt?
Add a Disallow directive for the URL path: User-agent: * followed by Disallow: /page-to-block/. This applies to all crawlers. To block only Googlebot, replace * with Googlebot. Note that disallowing a URL prevents crawling but does not guarantee de-indexing — if other sites link to the page, Google may still index it. Use a noindex tag for guaranteed de-indexing.
How do I allow all crawlers except one in robots.txt?
Create a User-agent block for the crawler you want to block with a Disallow: / rule, then create a separate User-agent: * block with Allow: /. Place the specific bot block before the wildcard block. For example, to block only GPTBot: User-agent: GPTBot then Disallow: / — all other crawlers continue to follow the wildcard allow rules.
Should I block CSS and JavaScript files in robots.txt?
No. Blocking CSS and JavaScript prevents Googlebot from rendering your pages correctly. Google needs to load these files to see your page as users see it. If these resources are blocked, Google may interpret your pages differently from their actual content, which can negatively affect how they rank. Only block resources with no public-facing value (admin pages, staging paths, session URLs).
How do I block AI crawlers in robots.txt?
Add specific User-agent blocks for each AI crawler you want to block: GPTBot (OpenAI), ClaudeBot and anthropic-ai (Anthropic), PerplexityBot (Perplexity), Google-Extended (Google Gemini AI training), and CCBot (Common Crawl). Note that blocking these crawlers prevents them from citing your content in AI-generated answers — weigh this against training data privacy concerns before blocking.
