A simple text file just placed in the root directory of your website informs mainly the search engine robots (such as Googlebot or Bingbot) about some areas of your site which they may or may not crawl. To put it in simple words, it's a set of rules defining what search engines can and cannot crawl regarding your site.

It is a simple text file that instructs search engine bots about which URLs they can crawl and more importantly which they cannot. It plays an essential role in technical SEO through which the search engines are controlled in their way of interacting with your site. Here is how this works:

User-agent specifies the bot (for example, Googlebot or Bingbot).
Disallow prevents crawling of certain URLs.
Allow permits particular pages found in blocked folders.
Sitemap directs the bots to your XML sitemap for better indexing.
By checking the robots.txt file before crawling, search engines can thus manage their SEO and crawling.

What Does User Agent Mean in Robots.txt ?

Specific bots can be defined such as Googlebot or Bingbot, or it can also be used as an asterisk(*) to cover all bots. For example, User-agent: * in conjunction with a Disallow rule disallows all crawlers from certain pages. The proper use of the User-agent line in your robots.txt allows you to fine-tune the way various robots interact with your site, implementing better control over SEO and crawl efficiency across search engines.

A robots.txt file disallows commands so search engine bots know which pages or directories can be crawled or indexed. For example, Disallow: /private/ restricts all bots away from the /private/ folder. This remains a very important SEO management command that stops the indexing of useless pages like admin pages or duplicate content. While Disallow does not prevent users from directly visiting those pages, it helps improve your site's crawl budget by disallowing the indexing of some non-public or irrelevant content, consequently enhancing its visibility to search engines.
