Robots.txt

A text file that tells web crawlers which pages or files they can or cannot request from your site.

Definition

Robots.txt is a file at the root of your website that indicates to search engine crawlers which parts of your site they should not access. While it doesn’t block crawlers from accessing your site, it serves as a guideline for ethical crawlers to follow, telling them which pathways are off-limits. This is mainly used to avoid overloading your site with requests or indexing content that you don’t wish to appear in search engine results.

Usage and Context

The robots.txt file is used by website owners to manage crawler traffic to their sites and ensure efficient site indexing. By specifying which areas of a site shouldn't be processed or scanned by search engine bots, site administrators can control the load on their servers and keep certain parts of the site private (though not securely hidden). It's especially useful for excluding duplicate content, private areas, or files that offer no value to search engine indexes from being crawled and indexed. Proper use of this file can improve a website's SEO by guiding search engine robots to the most valuable content.
