The Robots.txt Generator builds a correctly formatted robots.txt file for your website in seconds. Choose your default crawl rules, add specific allow or disallow paths, point to your sitemap, and copy the result to your site's root. Free, in-browser, and no signup.
Guide Search Crawlers the Right Way
A robots.txt file sits at your site's root and tells search engine crawlers which areas they may access. Getting it right matters — a stray rule can accidentally block your whole site, while a good one keeps bots focused on your important pages. This generator produces valid, properly formatted directives so you don't have to remember the syntax.
How to Use It
- Set default access — allow or disallow all robots.
- Add paths and your sitemap URL.
- Generate and copy the robots.txt content.
The Directives It Builds
| Directive | What it does |
|---|---|
| User-agent: * | Applies the rules to all crawlers |
| Disallow: /path/ | Asks bots not to access that path |
| Allow: /path/ | Explicitly permits a path |
| Sitemap: URL | Points crawlers to your XML sitemap |
An Important Nuance: robots.txt vs. noindex
A common misunderstanding: Disallow does not guarantee a page stays out of Google. It stops compliant crawlers from fetching the page, but a disallowed URL can still appear in results if other sites link to it, because Google may index the URL without crawling it. To reliably keep a page out of search, use a noindex meta tag — and don't disallow that page, so the tag can actually be seen.
robots.txt Is Guidance, Not Security
Reputable crawlers like Google and Bing honour robots.txt, but it's a voluntary standard — malicious bots and scrapers can ignore it. So never use it to hide sensitive content; that needs proper authentication. Think of robots.txt as polite instructions for well-behaved crawlers, not a lock.
Where It Goes
Upload the generated content as a plain text file named exactly robots.txt to your domain's root, so it's reachable at yoursite.com/robots.txt — the only place crawlers look. Free to generate as many as you need, with no signup.
Robots.txt Generator FAQs
What is a robots.txt file?
A robots.txt file is a plain text file placed in your website's root that tells search engine crawlers which parts of your site they may or may not access. It uses simple directives like User-agent, Disallow, Allow, and Sitemap. It's the standard way to guide crawler behaviour and is one of the first files search bots look for.
How do I use this generator?
Choose whether robots should be allowed or disallowed by default, optionally list specific paths to disallow or allow (one per line), and add your sitemap URL if you have one. The tool builds a correctly formatted robots.txt that you copy and upload to your site's root directory as a file named robots.txt.
What does Disallow do?
Disallow tells crawlers not to access a given path. For example, Disallow: /admin/ asks bots to stay out of your admin area. An empty Disallow (Disallow:) means nothing is blocked. Be careful: Disallow: / blocks your entire site from crawling, which you usually only want on staging sites.
Does robots.txt keep pages out of Google?
Not exactly, and this is an important nuance. Disallow stops compliant crawlers from fetching a page, but a disallowed URL can still appear in search results if other sites link to it, since Google may index the URL without crawling it. To reliably keep a page out of search, use a noindex meta tag (and don't disallow it, so the tag can be seen).
What is the Sitemap line for?
The Sitemap directive points crawlers to your XML sitemap, helping them discover all your important pages efficiently. Adding Sitemap: https://yoursite.com/sitemap.xml to your robots.txt is a simple, recommended way to make sure search engines know where your sitemap lives.
Do all bots obey robots.txt?
Reputable search engines like Google and Bing respect robots.txt, but it's a voluntary standard — malicious bots and scrapers can ignore it entirely. So robots.txt is for guiding well-behaved crawlers, not for security. Never rely on it to hide sensitive content; protect that with proper authentication instead.
Where do I put the robots.txt file?
It must go in the root of your domain, so it's reachable at yoursite.com/robots.txt. Crawlers only look for it there. Upload the generated content as a plain text file named exactly robots.txt to your site's root directory.
Is the tool free?
Yes, it's free with no signup. Generate as many robots.txt files as you need, right in your browser.
