Robots TXT Best Practice & Robots TXT Guide
Follow these golden rules from our robots txt guide during robots txt creation:
- Robots txt best practice: Always link your XML sitemap at the bottom of the file (
Sitemap: https://yourdomain.com/sitemap_index.xml). - Never disallow CSS or JS files: Modern Googlebot renders web pages like a full Chrome browser. Blocking stylesheets or JavaScript scripts will result in indexing penalties due to mobile-rendering errors.
- Do not use robots.txt to hide sensitive data: A robot txt file is completely public. Adding secret paths like
/secret-admin-login/openly advertises them to malicious scanners! Use server-side password authentication (HTTP 401) instead. - HTML robots vs robots.txt: To completely prevent a page from appearing in Google search results, use an html robots meta tag (
<meta name="robots" content="noindex">) and ensure the page is allowed in robots.txt so Googlebot can crawl and discover the noindex directive.
