About this tool

The robots.txt file is a critical SEO component that tells search engine crawlers which pages and directories they can and cannot access on your website. Placed in your website's root directory, it's the first file crawlers check before indexing your site. A properly configured robots.txt improves crawl efficiency, protects sensitive areas, and helps search engines focus on your important content.

Every website should have a robots.txt file. Without one, search engines may waste crawl budget on unimportant pages like admin panels, duplicate content, or staging directories. This can hurt your SEO by preventing search engines from efficiently indexing your valuable content. Our generator creates valid, properly formatted robots.txt files following the Robots Exclusion Protocol standard.

Common use cases include: blocking admin and login pages from search results, preventing indexing of duplicate content, protecting private directories, controlling crawl rate on bandwidth-limited servers, and guiding crawlers to your sitemap for complete site discovery.

The tool supports all major search engines (Google, Bing, Yahoo, Yandex) and allows you to set specific rules for different user agents, add multiple disallow rules, specify crawl delays, and include multiple sitemap URLs for comprehensive site coverage.

FAQs

What is robots.txt and why do I need it?

Robots.txt is a text file placed in your website root (yoursite.com/robots.txt) that tells search engine crawlers which pages they can access. It's essential for SEO - it prevents wasting crawl budget on unimportant pages, protects sensitive areas, blocks duplicate content from indexing, and guides crawlers to your sitemap.

Where should I put my robots.txt file?

Always place robots.txt in your website's root directory. It must be accessible at http://yoursite.com/robots.txt (not in subfolders). Search engine crawlers always check this exact URL first before crawling your site. If it's in the wrong location, it won't work.

What does "User-agent: *" mean?

User-agent: * means the rules apply to all search engine crawlers (Google, Bing, Yahoo, etc.). You can target specific crawlers like "User-agent: Googlebot" or "User-agent: Bingbot" to apply different rules to different search engines.

What's the difference between Allow and Disallow?

Disallow tells crawlers NOT to access specific paths (e.g., Disallow: /admin/ blocks the admin folder). Allow explicitly permits access, useful for allowing specific files in a blocked directory. If nothing is specified, crawlers can access everything by default.

Should I block pages I don't want in search results?

Be careful! Disallow in robots.txt only prevents crawling, not indexing. Pages may still appear in search results without descriptions. For pages you want completely removed from search, use robots.txt AND noindex meta tags, or use password protection.

What is crawl delay and should I use it?

Crawl-delay tells crawlers to wait X seconds between requests, preventing server overload. Only use it if you have limited bandwidth or your server struggles with crawler traffic. Google ignores crawl-delay (use Search Console instead), but Bing and other crawlers respect it.

How do I add my sitemap to robots.txt?

Add "Sitemap: https://yoursite.com/sitemap.xml" anywhere in your robots.txt file (conventionally at the end). You can list multiple sitemaps. This helps crawlers discover all your pages faster, improving indexing efficiency.

Can robots.txt block malicious bots?

No. Robots.txt is a gentleman's agreement - only well-behaved crawlers follow it. Malicious bots, scrapers, and hackers ignore robots.txt. To block bad bots, use .htaccess rules, server-level blocking, or WAF (Web Application Firewall) solutions.
