What Is a robots.txt File?

A robots.txt file is a text file placed at the root of your website that tells search engine crawlers which pages they can and cannot access. It follows the Robots Exclusion Protocol and is the first file crawlers check before indexing your site. Properly configured robots.txt helps search engines crawl your site efficiently and keeps private or duplicate content out of search results.

How Do I Create a robots.txt File?

Select which user agents (search engine bots) to configure, specify allowed and disallowed paths, and add your sitemap URL. The tool generates the properly formatted robots.txt content. Copy it and upload it to your website's root directory so it is accessible at yourdomain.com/robots.txt.

What Should I Block in robots.txt?

Common paths to disallow include admin panels, user account pages, search result pages, print-only versions, staging or development directories, and any content that should not appear in search results. Avoid blocking CSS and JavaScript files, as search engines need these to render your pages properly.

Does robots.txt Guarantee Pages Won't Be Indexed?

No. robots.txt is a voluntary standard — well-behaved crawlers honor it, but malicious bots may ignore it. Additionally, a page can still appear in search results if other sites link to it, even if robots.txt disallows crawling. For true exclusion from search results, use the noindex meta tag or X-Robots-Tag HTTP header.

What Happens If I Don't Have a robots.txt File?

If your site has no robots.txt, search engine crawlers will attempt to crawl every page they can find. This is fine for most small sites. However, without robots.txt you cannot prevent crawling of admin pages, duplicate content, or resource-heavy sections. You also cannot point crawlers to your sitemap. Having a robots.txt — even a minimal one that just references your sitemap — is a best practice for all websites.
