interprets the robots.txt specification</h1> <p> Google's automated <a href="/search/docs/crawling-indexing/overview-google-crawlers">crawlers</a> support the <a href="https://www.rfc-editor.org/rfc/rfc9309.html" class="external-link">Robots Exclusion Protocol (REP)</a>. This means that before crawling a site, Google's crawlers download and parse the site's robots.txt file to extract information about which parts of the site may be crawled. The REP isn't applicable to Google's crawlers that are controlled by users (for example, feed subscriptions), or crawlers that are used to increase user safety (for example, malware analysis). </p> <p> This page describes Google's interpretation of the REP. For the original standard, check <a href="https://www.rfc-editor.org/rfc/rfc9309.html" class="external-link">RFC 9309</a>. </p> <h2 id="what-is-a-robots.txt-file" data-text="What is a robots.txt file" tabindex="-1">What is a robots.txt file</h2> <p> If you don't want crawlers to access sections of your site, you can create a robots.txt file with appropriate rules. A robots.txt file is a simple text file containing rules about which crawlers may access which parts of a site. For example, the robots.txt file for example.com may look like this: </p> <div></div><devsite-code><pre translate="no" dir="ltr" is-upgraded># This robots.txt file controls crawling of URLs under https://example.com. # All crawlers are disallowed to crawl files in the "includes" directory, such # as .css, .js, but Google needs them for rendering, so Googlebot is allowed # to crawl them. User-agent: * Disallow: /includes/ User-agent: Googlebot Allow: /includes/ Sitemap: https://example.com/sitemap.xml</pre></devsite-code> <p> If you're new to robots.txt, start with our <a href="/search/docs/crawling-indexing/robots/intro">intro to robots.txt</a>.
