What is a Robots.txt file?

A Robots.txt file is an essential SEO tool that instructs search engine crawlers which areas of a website to index. Learn more about its function and importance.

What is a Robots.txt file?

The Robots.txt file is a simple text file that is placed on web servers and is used to instruct search engine crawlers which areas of a website should and should not be indexed. It is an essential tool in search engine optimization (SEO) to ensure that only relevant content is captured and indexed by search engines.

How the Robots.txt file works

The Robots.txt file is stored in the root directory of a web page and usually contains one or more rules that are defined based on user agents. User agents are identifiers of search engine crawlers, such as Googlebot or Bingbot, that are addressed by the file. The rules contain instructions in the form of disallow and allow directives to block or allow certain areas of a page for crawling.

Example of a Robots.txt file

User-agent: \*
Disallow: /internal/
Disallow: /wp-admin/
Disallow: /private/
Allow: /wp-content/uploads/

In this example, the Robots.txt file contains instructions that apply to all user agents. It blocks access to the /intern/, /wp-admin/, and /private/ directories for crawling and allows access to the /wp-content/uploads/ directory.

Robots.txt file and SEO

A carefully configured Robots.txt file can have positive effects on the ranking of a website in search engines. By blocking irrelevant or duplicate content, crawling can be more efficient and targeted, resulting in better indexing of important content. However, it is important to pay attention to which areas of the web page are blocked in the Robots.txt file to avoid unintended consequences.

Be careful when using the Robots.txt file

Some website operators use the Robots.txt file to hide sensitive content or documents from search engines. However, it should be noted that the Robots.txt file is publicly accessible and can be read by the curious or bots. A better solution for blocking sensitive content is access restrictions using passwords or a server-side configuration, for example.
