Give Search Engines Precise Crawling Instructions

The robots.txt file sits in your website’s root directory and acts as a gatekeeper for well‑behaved crawlers. It tells them which parts of your site they are allowed to access and index, and which they should skip. This is crucial for saving crawl budget on large sites, preventing indexing of duplicate content, staging environments, or sensitive areas like admin panels. A single syntax error in robots.txt can block your entire site from Google—a nightmare that’s easily avoided. Our Robots.txt Generator uses a simple visual builder: you set rules, it writes the flawless code. No manual typing of Disallow: directives required.

Features of the Builder

• User‑agent specific rules: Add rules for all bots (User-agent: *) or target specific bots like Googlebot, Bingbot, Baiduspider, etc. A handy dropdown lists common bot names.
• Allow and Disallow directives: For a path, choose whether to allow or disallow crawling. The generator prevents contradictory rules.
• Crawl‑delay setting: Set a polite delay in seconds between requests for specific bots, useful for slow servers.
• Sitemap location: Include one or more Sitemap: directives pointing to your XML sitemaps. This helps bots find your sitemap even without submitting it to Search Console.
• Pattern matching: Use * (wildcard) and $ (end of URL) to block ranges of URLs. The builder validates the syntax.
• Real‑time preview and validation: The robots.txt content updates as you add rules. It also checks for common mistakes (e.g., Disallow: empty, blocking everything by accident).
• Import existing robots.txt: You can paste your current file, edit it visually, and re‑export.

Step‑by‑Step: Build Your robots.txt

1. Start with a default rule for all bots: User-agent: *. Typically, you then add Disallow: for paths you want to block. Leave Disallow: alone if you want to allow everything (the default).
2. Add disallowed paths. E.g., /wp-admin/, /cgi-bin/, /staging/, /*?* (to block all parameter URLs), or /private/*. The tool helps you write the correct pattern.
3. If needed, add specific Allow rules that override broader Disallow rules for specific bots.
4. Set crawl delays for problematic bots (often just a few seconds).
5. Add your sitemap URL at the bottom: Sitemap: https://yoursite.com/sitemap.xml. You can add multiple sitemap lines.
6. Review the live robots.txt in the code panel. Check for any warnings (red highlights).
7. Download or copy the file. Upload it to your website’s root (https://yoursite.com/robots.txt).
8. Test it using Google Search Console’s robots.txt Tester, or simply with our Site Crawler which respects robots.txt.

Common Use Cases

• Blocking staging or dev sites: Disallow: / for the entire staging subdomain so it never appears in search.
• Crawl budget optimisation: Block infinite spaces like calendar pages, search results, or filtered faceted navigation.
• Preventing image indexation: Disallow /images/private/.
• Blocking specific bots that only cause server load.

Integration with Other Tools

Combine with the Sitemap Generator to get the exact sitemap URL to include. Use the Site Crawler to verify that your blocked pages are indeed blocked, and allowed pages are crawled. The Redirect Checker ensures no blocked pages are accidentally redirecting elsewhere. For advanced server rules, the Htaccess Generator provides another layer of control. And for international sites, the Hreflang Generator works alongside your robots directives. Proper crawl management is foundational SEO.
