Search Bot Specific Rules

Restricted Directories (Disallow Directives)

Important: robots.txt is a public file, not an access-control or security mechanism. Listing private paths here makes them visible to anyone.
Quick add:

Generated Robots.txt

/robots.txt (UTF-8)0 lines · 0 directives
Your robots.txt file has been generated!

Download or copy the above content and upload it to your website's root directory (e.g., https://example.com/robots.txt).

Crawling vs. Indexing

Disallow stops compliant crawlers from fetching a URL, but does not guarantee the URL won't appear in search results if external pages link to it. To keep a page out of search results, allow crawling and serve a <meta name="robots" content="noindex"> tag or HTTP X-Robots-Tag: noindex header, or require authentication.

Crawl-Delay & Bot Support

Crawl-delay is an unofficial extension ignored by Googlebot and interpreted differently by Bingbot, Yahoo Slurp, and Yandex. Historical tokens (such as Robozilla, Teoma, Gigabot, and psbot) are included for legacy rule compatibility; regional crawlers follow their own specifications.

Keep CSS & JS Unblocked

Never block essential CSS stylesheets, JavaScript bundles, or public image/font assets by default. Modern search engines render pages using a headless browser and need access to those resources to evaluate mobile-friendliness, layout stability, and page content.

How to create a robots.txt file

  1. Pick a preset or start blank.
  2. Add paths to block, such as /admin/ or /cart/.
  3. Paste your sitemap URL.
  4. Copy the result into a file named robots.txt.
  5. Upload it to your site root, so it opens at yourdomain.com/robots.txt.

Data processing and privacy

All crawler rules, directory paths, and sitemap URLs are processed locally in your browser. Nothing is transmitted to or stored on RankSmartTools servers. Remember that once you publish robots.txt at your domain root, the file itself is publicly readable.

Practical example

Keep Default Robot Access set to Allow All, add internal paths like /cgi-bin/ or /staging/ under Restricted Directories, paste your https://example.com/sitemap.xml URL, and download robots.txt for your site root.

Troubleshooting

If a disallowed URL still appears in Google search results, remember that robots.txt controls crawling rather than indexing. Allow crawling of the URL and add a meta robots noindex tag or X-Robots-Tag HTTP header, or protect private areas with authentication.

Frequently asked questions

No. Disallow directives instruct compliant crawlers not to fetch (crawl) the URL, but search engines can still index the URL if external or internal pages link to it. To prevent a page from appearing in search results, allow crawling and serve a meta robots noindex tag or X-Robots-Tag: noindex HTTP header, or protect the page with authentication.

No. Googlebot ignores the Crawl-delay directive in robots.txt. Some other crawlers—including Bingbot, Yahoo Slurp, and Yandex—recognize Crawl-delay to varying degrees.

No. Because robots.txt is publicly accessible at https://yourdomain.com/robots.txt, listing secret or administrative URLs in Disallow rules reveals their existence to anyone. Always protect confidential directories with authentication and server-side access control.

No. Search engines render pages using a headless browser and need access to CSS stylesheets, JavaScript bundles, and public assets to evaluate layout, mobile-friendliness, and page content.

Place the UTF-8 plain-text file named robots.txt (all lowercase) in the top-level root directory of your domain or subdomain, such as https://www.example.com/robots.txt.
