Robots.txt Generator
Generate a robots.txt file for your website. Control search engine crawlers easily.
About the Robots.txt Generator
The Robots.txt Generator produces a valid robots.txt file that controls exactly which crawlers can access which parts of your website. A well-written robots.txt guides Googlebot, Bingbot and other search-engine crawlers to your most important pages while blocking them from admin panels, staging paths, duplicate content and infinite-scroll traps that would otherwise waste crawl budget. The generator supports multiple user-agents, allow / disallow rules, crawl-delay directives and inline sitemap references, and outputs a clean, ready-to-upload file in seconds.
robots.txt is a plain-text file placed at the root of your domain (yoursite.com/robots.txt) that tells web crawlers which parts of the site they may or may not visit. It follows the Robots Exclusion Protocol, a longstanding informal standard now recognised as RFC 9309. A correct robots.txt is one of the smallest files on your site but has one of the largest impacts on how efficiently search engines crawl and index your content.

Allow & Disallow directives
Fine-grained include/exclude control over any path or file pattern.
Sitemap reference
Automatically appends Sitemap: URLs so every crawler discovers your XML sitemap.
Crawl-delay setting
Ease server load by asking crawlers to wait N seconds between requests.
Live preview
The generated robots.txt renders live in a monospace box as you edit rules.
Copy or download
Grab the output as text or download it as robots.txt ready for upload.
How to Use the Robots.txt Generator
Follow these simple steps to get accurate results in seconds. No sign-up, no download, no watermark — just paste, click, and copy.
- 1
Choose the crawlers to configure
Start with User-agent: * for a universal rule, then add specific bots (Googlebot, Bingbot) if you need different behaviour.
- 2
Add allow / disallow paths
Common disallowed paths: /admin/, /cart/, /search/, /*?*. Common allowed paths: everything else.
- 3
Reference your sitemap
Add Sitemap: https://yoursite.com/sitemap.xml at the bottom so crawlers can find your index of URLs.
- 4
Copy or download
Grab the finished file and upload it to the root of your web server.
- 5
Verify with Google Search Console
Use GSC’s robots.txt tester to confirm your rules work as intended before relying on them.
Why Choose Our Robots.txt Generator?
Preserve crawl budget
Blocking low-value pages (search results, filter combos, admin areas) lets crawlers spend their limited budget on pages that actually matter.
Prevent duplicate content indexing
Search-engine crawlers stop hitting URL variants that would otherwise pollute the index.
Protect staging environments
Block internal or staging paths from being crawled before they are ready for public search.
Improve site speed
Fewer crawler hits on expensive endpoints means faster page loads for real visitors.
Common Use Cases
The Robots.txt Generator is trusted by students, writers, marketers, developers and everyday users worldwide. Here are some of the most common scenarios where it saves time and delivers reliable results.
E-commerce sites
Block cart, checkout, filter and internal-search URLs from the index.
Content publishers
Point crawlers to fresh articles while excluding archive filter pages.
SaaS platforms
Keep authenticated app routes (/app/, /dashboard/) out of the public index.
Development teams
Prevent staging.yoursite.com from being crawled and indexed by mistake.
AI compliance teams
Selectively block or allow AI-training crawlers (GPTBot, ClaudeBot, CCBot) based on your usage policy.
Best Practices & Tips
Never disallow /
Disallow: / blocks your entire site from being crawled — a catastrophic mistake we still see once a month.
Do not use robots.txt for security
It is a public file — anyone can read it. Do not list URLs you want kept truly secret; use HTTP auth or noindex instead.
Include only one Sitemap: line per index
Multiple sitemap references are fine, but avoid duplicates.
Test before deploying
A tiny typo can dis-allow your entire site. Always validate in Google Search Console before publishing.
Frequently Asked Questions
Where does robots.txt live?
At the root of your domain — yoursite.com/robots.txt. It cannot be placed in a subdirectory and still be recognised.
Does robots.txt guarantee a page will not be indexed?
No. It only prevents crawling. To prevent indexing, use a noindex meta tag or an X-Robots-Tag HTTP header.
Do search engines honour crawl-delay?
Bing and Yandex do; Google ignores crawl-delay and expects webmasters to use Search Console’s crawl-rate settings instead.
What is the difference between Allow and Disallow?
Disallow blocks paths that match; Allow explicitly permits paths inside a disallowed range — useful for exceptions.
Can I have multiple sitemaps?
Yes — add one Sitemap: line per sitemap file. Or point to a sitemap index that lists them all.
Does robots.txt affect ranking?
Not directly. But by shaping crawl priority, it indirectly influences how quickly and completely your important pages get indexed.
Can I block AI crawlers?
Yes — add User-agent: GPTBot / ClaudeBot / CCBot / anthropic-ai etc. and Disallow: / for each. Note that not all AI bots respect robots.txt.
What happens if robots.txt is missing?
Crawlers assume all paths are permitted and crawl freely. That is often fine for small sites but wasteful for large ones.
Can I use wildcards?
Yes — most major crawlers support * (any characters) and $ (end of URL). E.g. Disallow: /*?* blocks all URLs with query strings.

Privacy, Security & Trust
The Robots.txt Generator is built with a privacy-first philosophy. Every calculation, encoding and transformation runs entirely inside your web browser using standard JavaScript APIs — nothing you type, paste or upload is transmitted to our servers, logged, cached or shared with any third party. You can verify this yourself by opening your browser's developer tools and watching the Network tab while you use the tool: you will see zero outbound requests for the actual computation.
This client-side architecture matters most when you are working with sensitive text — an unpublished blog draft, a legal notice under embargo, an internal meta description, or a password you are about to set. On many competing sites, similar tools quietly send every keystroke to their servers for "processing", which becomes a real leak vector. Ours does not, and it never will.
The tool is completely free with no daily quotas, no watermarks and no forced sign-up. It works on desktop and mobile browsers, on slow and fast connections, and continues to function offline once the page has loaded. All source code, formulas and character tables used by the tool are standard, well-documented and independently verifiable — which is essential for anything you plan to use for legal, medical, financial or educational purposes.
