What Does Robot.txt Do? A Comprehensive Guide to Robot.txt

Introduction

Robot.txt is a text file used by webmasters to control access to their websites. It is a powerful tool that can help you protect your website from malicious web crawlers, reduce site load time and improve SEO rankings. In this article, we will explore the basics of Robot.txt and discuss how it can benefit your website.

Exploring the Basics of Robot.txt and How It Can Help Your Website

Robot.txt is a file stored in the root directory of a website. It contains instructions for web crawlers on how to access certain parts of the website. By creating and submitting a Robot.txt file to search engines, webmasters can control which pages are indexed and which ones are left out.

What Are the Key Components of Robot.txt?

The Robot.txt file consists of two key components: user-agent directives and crawl delay directives. The user-agent directive tells the web crawler which pages should be accessed and which ones should not. The crawl delay directive sets the rate at which the web crawler should visit the website.

How to Create a Robot.txt File

Creating a Robot.txt file is relatively simple. All you need to do is create a text file with the name “Robot.txt”, add the necessary directives and upload it to the root directory of your website. You can also use online tools such as Google’s Webmaster Tools to create your Robot.txt file.

How to Use Robot.txt to Control Access to Your Site

Once you have created your Robot.txt file, you can use it to control access to your website. To do this, you need to specify the user-agent directive in your Robot.txt file. This directive tells the web crawler which pages should be accessed and which ones should not. For example, if you want to block all web crawlers from accessing certain pages on your website, you can add the following line to your Robot.txt file:
User-agent: *
Disallow: /path-to-page/
This directive tells the web crawler not to access the specified page. You can also use the Robot.txt file to limit the rate at which the web crawler visits your website. To do this, you need to add the following line to your Robot.txt file:
Crawl-delay: [number]
This directive tells the web crawler to wait for the specified number of seconds before accessing the next page on your website.
