Select which directories to block, which crawlers to restrict, and point to your sitemap — then copy the output and add it to your site root.
Why this tool is needed
The tool builds a robots.txt file with User-agent directives, Disallow rules, Allow rules, and a Sitemap reference. It uses proper syntax for all major crawlers (Googlebot, Bingbot, etc.) and formats the output with correct line breaks and indentation.

Role in SEO
Without a robots.txt file, crawlers index everything — including admin pages, duplicate content, and staging environments. This wastes crawl budget and can dilute your site's authority. A well-configured robots.txt directs crawlers to your most important pages, improves crawl efficiency, and prevents sensitive directories from appearing in search results.

Frequently asked questions
Where should I put my robots.txt file?
Place it in your site's root directory (https://www.example.com/robots.txt). Search engines look for it at this exact path.
Can robots.txt prevent indexing?
No. robots.txt controls crawling, not indexing. To prevent indexing, use a noindex meta tag or X-Robots-Tag header. Crawlers that ignore robots.txt can still index blocked pages.
Should I block my admin pages?
Yes. Block /admin/, /wp-admin/, and login pages to prevent crawlers from wasting budget on non-public content.
Do I need separate rules for Google and Bing?
Usually not. A single User-agent: * rule covers most crawlers. Add specific rules only if you need different behavior for a particular bot.
How does robots.txt affect crawl budget?
By blocking low-value pages (admin, duplicate content, filters), you focus crawl budget on your most important content, leading to faster indexing of new pages.

- Keep the file in your site's root directory (/robots.txt)
- Don't use robots.txt to hide content — use noindex meta tags instead
