Robots.txt Complete Guide — What It Is and How to Create One

Master robots.txt from scratch! Learn what it is, how to create one, common rules, and how it controls what search engines crawl.

Every website needs a robots.txt file. It tells search engine crawlers which pages to index and which ones to skip. Without a properly configured robots.txt, search engines might crawl unnecessary pages or miss important ones.

What is Robots.txt?

Robots.txt is a plain text file placed in the root directory of your website. It provides instructions to web crawlers (like Googlebot) about which URLs they can and cannot access on your site.

Basic Syntax

User-agent: Specifies which crawler the rules apply to.
Disallow: Blocks crawlers from accessing specified paths.
Allow: Explicitly permits crawling of specified paths.
Sitemap: Points to your XML sitemap location.

Common Examples

Block all crawlers from a directory:
User-agent: *
Disallow: /admin/
Disallow: /private/

Allow all crawlers everywhere:
User-agent: *
Disallow:
