About the Robots.txt Generator
The robots.txt file is a plain-text file placed at the root of your domain (e.g., https://example.com/robots.txt) that tells web crawlers which parts of your site they may or may not access. It follows the Robots Exclusion Protocol (REP).
While robots.txt does not prevent pages from being indexed if other sites link to them, it is the standard way to prevent crawlers from wasting crawl budget on low-value pages like admin panels, duplicate content, or staging areas. All major search engine bots — Googlebot, Bingbot, DuckDuckBot — respect robots.txt.
How to Generate a robots.txt File
Add a Rule Block
Click "Add Rule Block" to create a block for a user-agent. Select a specific crawler or use * for all bots.
Set Allow / Disallow Paths
Add paths you want to allow or disallow. Use /admin/ to block a directory, or / to block everything.
Add Your Sitemap
Paste your sitemap URL at the bottom so search engines can find and index your pages efficiently.
Download & Upload
Click "Download robots.txt" and upload the file to the root of your web server or S3 bucket.
Frequently Asked Questions
The robots.txt file must be at the root of your domain: https://yourdomain.com/robots.txt. Placing it in a subdirectory (e.g. /blog/robots.txt) will not work — crawlers only look for it at the root.
Disallow prevents crawlers from visiting the URL, but does not guarantee the page won't appear in search results. If another site links to the blocked page, Google may still index it with a "No information is available for this page" snippet. To reliably prevent indexing, use a noindex meta tag or the X-Robots-Tag HTTP header.
Allow: / grants access to the entire site for a specific user-agent. It is commonly used after a broad Disallow to re-allow specific paths. If no Disallow rule is present, Allow is redundant since all paths are allowed by default.
No. You should allow Googlebot to access your CSS, JavaScript and image files. Blocking these resources prevents Google from fully rendering your pages, which can negatively impact rankings. Google explicitly recommends not blocking these resource types.
