Common Use Cases

Block admin and login pages

Prevent search engines from crawling and potentially indexing your wp-admin, login, and private admin directories.

Protect development environments

Block crawlers from indexing staging, dev, or test subdirectories that shouldn't appear in search results.

Set crawl budget efficiently

Use crawl delay to slow down aggressive bots on shared hosting, or direct crawl budget away from low-value pages.

Combine with sitemap

Link your sitemap.xml in robots.txt so Google and Bing can discover all your pages faster — the most important robots.txt directive.

What is a robots.txt file?

A robots.txt file tells search engine crawlers which pages or directories of your website they should or should not crawl. It's placed in the root of your domain (yoursite.com/robots.txt) and is checked by Googlebot before crawling begins.

Does robots.txt prevent pages from being indexed?

No — robots.txt only controls crawling, not indexing. Google can still index a URL it hasn't crawled if other sites link to it. Use noindex meta tags or the X-Robots-Tag header to prevent indexing.

What is crawl delay in robots.txt?

Crawl-delay tells crawlers how many seconds to wait between requests. Google ignores this directive — use Google Search Console to set crawl rate for Googlebot instead. Crawl-delay is honored by Bing, Yandex, and other crawlers.

robots.txt: Common Rules and What They Mean

✓ User-agent: * (all crawlers)
Applies rules to all search engine bots. Most sites start with this and add specific rules for individual crawlers.
✓ Disallow: /admin/
Blocks all crawlers from accessing the /admin/ directory and everything inside it. Common for WordPress, Django, and CMS admin panels.
✓ Allow: /api/public/
Explicitly allows crawling of a subdirectory even when its parent is disallowed. Useful for public API endpoints within a larger blocked section.
✓ Sitemap: https://yoursite.com/sitemap.xml
The most valuable directive — tells all crawlers where to find your sitemap for faster page discovery and better crawl coverage.

Frequently Asked Questions

Where do I upload the robots.txt file?+
The robots.txt file must be in the root directory of your website — at yourwebsite.com/robots.txt. Upload via FTP to public_html/ or use cPanel File Manager.
What happens if I have no robots.txt file?+
Crawlers will crawl everything they can find. This is fine for most sites. Crawlers assume full access if no robots.txt file exists.
Should I block CSS and JavaScript files?+
No — this was recommended in old SEO guides but is now outdated. Google needs to crawl CSS and JS to render your pages correctly for indexing. Don't block them.
Can I have multiple User-agent sections?+
Yes. You can specify different rules for different crawlers: User-agent: Googlebot with specific rules, then User-agent: * with general rules. Toolzoid's generator supports this with the crawler selector.
