What Is robots.txt?

Robots.txt is a text file placed in your website root directory that instructs search engine crawlers which pages or files they can or cannot request from your site. It is a fundamental part of technical SEO and helps you control how search engines interact with your website content.

Frequently Asked Questions

Where should I place my robots.txt file?

Place your robots.txt file in the root directory of your website (e.g., yoursite.com/robots.txt). It must be accessible at this exact URL.

Can robots.txt prevent pages from appearing in search results?

No, robots.txt only controls crawling behavior. To prevent pages from appearing in search results, use the noindex meta tag or X-Robots-Tag HTTP header.

Is robots.txt required for my website?

While not strictly required, robots.txt is recommended for most websites to control crawler access and improve SEO efficiency.

Can I use wildcards in robots.txt?

Yes, you can use asterisks (*) as wildcards and $ to mark the end of a URL. For example, Disallow: /*.pdf blocks all PDF files.

How do I know if my robots.txt is blocking important pages?

Use our robots.txt checker to see which URLs are blocked. If important pages are blocked, update your robots.txt to allow them.
