Robots.txt Generator
The robots.txt file is one of the first things search engine crawlers look at when they visit your website, and getting it wrong can accidentally block your best pages from appearing in search results. Our robots.txt generator helps you create a properly formatted file without needing to memorize the syntax or worry about typos breaking everything. Just select which search engines to allow or block, specify which folders to exclude, point to your sitemap, and get a ready-to-upload robots.txt file in seconds. No coding required, no guessing about the format.
What Is
A robots.txt generator is a tool that creates the robots.txt file — a simple text file placed in your website's root directory that tells search engine crawlers which pages they're allowed and disallowed to access. The file follows the Robots Exclusion Protocol, a widely respected standard used by Google, Bing, Yahoo, and virtually every other search engine. The robots.txt file works like a set of instructions: you can tell all bots to stay out of certain directories, block specific bots from your entire site, or allow everything except a few private folders. The file uses a straightforward syntax with directives like User-agent (which bot you're talking to), Disallow (paths to block), Allow (paths to permit), and Sitemap (where your sitemap lives). Getting this file right matters because a mistake can have serious consequences. A typo in a Disallow line could accidentally block your entire site from Google. On the flip side, a well-configured robots.txt can prevent thin or duplicate content from being indexed, reduce server load from excessive crawling, and keep private areas like admin panels out of search results.
How to Use
- Choose your default access policy — whether you want to allow all bots to crawl your site or start with a more restrictive approach.
- Add specific rules for individual search engine bots if you want different access levels for Google, Bing, or other crawlers.
- Specify which directories or file types you want to block from being crawled, such as admin folders, private areas, or duplicate content sections.
- Add your sitemap URL to help search engines discover and index your important pages more efficiently.
- Copy the generated robots.txt content and upload it to your website's root directory, then test it using Google Search Console's robots.txt tester tool.
Examples
Input: Allow: all, Sitemap: yes
Process: Generate User-agent star then no disallow then Sitemap directive
Result: User-agent: star Disallow: Sitemap: https://example.com/sitemap.xml
Input: Disallow: /admin and /private
Process: Block admin and private paths then allow rest
Result: User-agent: star Disallow: /admin Disallow: /private Allow: /

Frequently Asked Questions
What happens if I don't have a robots.txt file?
Without a robots.txt file, all search engine crawlers assume they're allowed to crawl everything on your site. For most small websites this is fine — it just means Google and Bing will try to index everything they can find. However, if you have private areas, duplicate pages, or dynamically generated URLs that create thin content, those will get indexed too. Having at least a basic robots.txt that points to your sitemap is considered a best practice.
Can robots.txt prevent people from seeing my pages?
No — robots.txt only instructs search engine crawlers. It does not block human visitors or prevent anyone from accessing a URL directly. If you need to keep pages truly private, use password protection or authentication. Anyone can view your robots.txt file by visiting yourdomain.com/robots.txt, so don't rely on it to hide sensitive information or secret page URLs.
Will blocking a page in robots.txt remove it from Google?
Blocking a page in robots.txt prevents Google from crawling it, but it doesn't guarantee removal. If Google already indexed the page, the URL might still appear in search results without a description. To remove a page from search results quickly, use Google Search Console's removal tool or add a noindex meta tag to the page. For the cleanest result, use both noindex and a removal request together.
How do I know if my robots.txt is working?
Use Google Search Console's robots.txt Tester tool — it shows you exactly how Googlebot interprets your file and flags any syntax errors or issues. You can also test specific URLs to see if they're blocked or allowed. Bing Webmaster Tools offers a similar tester. Regularly checking ensures your rules are working as intended and haven't been broken by edits.
What's the difference between robots.txt and a noindex tag?
Robots.txt tells crawlers not to visit a page at all, while a noindex meta tag allows crawling but tells search engines not to include the page in search results. The key difference is that robots.txt blocks access to the page content itself during crawling, which means Google might not see a noindex tag if robots.txt is blocking the page first. For guaranteed exclusion from search results, use a noindex tag on the page itself.
