Robots.txt Generator
Create custom robots.txt files to control search engine crawlers.
📖 Complete Guide to Robots.txt Files
The robots.txt file is one of the most important yet often overlooked files on any website. This simple text file, placed in your site's root directory, communicates directly with search engine crawlers and other web robots, telling them which pages they can and cannot access. A properly configured robots.txt can improve your SEO performance, protect private content, and manage your server's crawl budget efficiently.
Despite its simplicity, robots.txt is frequently misconfigured, leading to serious consequences—from accidentally blocking your entire site from search engines to exposing sensitive URLs. Our Robots.txt Generator helps you create properly formatted files with confidence, whether you're setting up a new website or optimizing an existing one.
📜 Understanding Robots.txt Directives
| Directive | Syntax | Purpose | Example |
|---|---|---|---|
| User-agent | User-agent: [name] | Specifies which crawler the rules apply to | User-agent: Googlebot |
| Disallow | Disallow: [path] | Blocks access to specified path | Disallow: /private/ |
| Allow | Allow: [path] | Explicitly permits access (overrides Disallow) | Allow: /public/ |
| Sitemap | Sitemap: [URL] | Points crawlers to your XML sitemap | Sitemap: https://site.com/sitemap.xml |
| Crawl-delay | Crawl-delay: [seconds] | Requests delay between crawler requests | Crawl-delay: 10 |
🤖 Common Search Engine Crawlers
| User-agent | Search Engine | Notes |
|---|---|---|
| * | All crawlers | Wildcard matching any bot |
| Googlebot | Google Search | Primary Google web crawler |
| Googlebot-Image | Google Images | Specifically for image search |
| Bingbot | Microsoft Bing | Also powers Yahoo and DuckDuckGo |
| Yandex | Yandex (Russia) | Major search engine in Russian markets |
| Baiduspider | Baidu (China) | Dominant search engine in China |
| DuckDuckBot | DuckDuckGo | Privacy-focused search engine |
📋 Template Explanations
Our generator includes four pre-built templates for common scenarios:
- Allow All: The most permissive setting—all crawlers can access all content. Ideal for most public websites that want maximum search visibility. Simply allows "/" which means the entire site.
- Block All: Completely prevents all search engine crawling. Use this for development/staging sites, private intranets, or sites under construction. Disallows "/" which blocks everything.
- WordPress: Optimized for WordPress installations. Blocks admin areas, includes files, and feeds while allowing the admin-ajax.php file needed for some front-end functionality. Protects your backend without breaking site features.
- Custom: Start from scratch and build exactly the configuration you need. Add specific rules for your site's unique structure and requirements.
💡 Important: Robots.txt is publicly accessible—anyone can view it at yourdomain.com/robots.txt. Never use it to hide truly sensitive content like admin pages, user data, or confidential documents. Determined attackers will simply ignore it. Use proper authentication, access controls, and "noindex" meta tags for genuine security.
🎯 Best Practices
- Always include a Sitemap: Helps search engines discover all your important pages efficiently
- Test before deploying: Use Google Search Console's robots.txt tester to verify your configuration
- Be specific with paths: "/admin" blocks /admin, /admin/, /administrator, etc. Use "/admin/" for just that directory
- Don't block CSS/JS: Google needs these to render and understand your pages properly
- Update after site changes: Review robots.txt when adding new sections or restructuring URLs
- Monitor in Search Console: Check for crawl errors that might indicate robots.txt problems
