How Does a Robots.txt File Work?

The working of a Robots.txt file is pretty straightforward. Simply, it tells SERPs which sections of the websites need to be crawled. 

Let’s understand this with an example. 

A website named “www.example.com”  has given the below instructions. This states that all bots can crawl the website except “GPTBot.”

Caution: Be careful while working with the Robots.txt file because a simple mistake, like accidentally blocking Googlebot from your entire site, can be a major setback.  It’s like slamming the door shut on search engines, affecting your site’s visibility. That’s why you should always double-check your directives to avoid unexpected issues. 

IMPORTANT: A Robots.txt file can only provide instructions but can’t force them. Responsible bots will respect these directives and crawl only the designated areas. 

However, it’s essential to acknowledge that some less scrupulous bots, such as spam or malicious web crawlers, may disregard these guidelines.

Importance of Robots.txt

• Managing site architecture

Robots.txt file plays a vital role in managing the architecture of a website. It guides the search engine bots through the most important sections of the site while excluding less critical or duplicate content.  

• Prevent duplicate content issues 

Do you know search engines can penalize your website for duplicate content? How to avoid this concern? Robots.txt will help as it automatically excludes certain sections or URLs. 

• Protect sensitive information

Robots.txt allows website owners to prevent sensitive information, such as personal data, login pages, or administrative sections, from being indexed on SERPs.

What Are The Best Practices For Robot.txt Files?

1. Ensure Clean Formatting

Separate each directive with a new line in your robots.txt file. If instructions are jumbled together, search engines might overlook them, rendering your efforts ineffective.

Avoid: User-agent: * Disallow: /admin/

Disallow: /directory/

Prefer: User-agent: *

Disallow: /admin/

Disallow: /directory/

2. Simplify with Asterisk

Use asterisks (*) to apply directives universally. Instead of listing out individual URLs, asterisk usage streamlines instructions. 

3. End URLs Effectively

Use the “$” symbol to signify the end of a URL pattern. This prevents inefficient listing of individual files. 

For instance, 

User-agent: *

Disallow: /*.jpg$

4. Use Hash for Comments:

Insert comments with the “#” symbol. Crawlers disregard commented lines, making it an effective way to add notes for organization and readability.

5. Make different Robots.txt file for different domains 

Maintain separate robots.txt files for different subdomains, as each file only influences crawling behavior within its respective subdomain.

Frequently Asked Questions (FAQs)

1. How can I check if my website has a robots.txt file?

You can check if your website has a robots.txt file by following the simple steps below. 

• Type your website’s root domain in the address bar, like www.example.com. 
• Extend the URL by adding “/robots.txt” to the end. So, for our example, it would be w3speedup.com/robots.txt. 
• Hit Enter to load the URL. 
• If a robots.txt file exists, you will see its content displayed in your browser. 
• If you don’t see any .txt page or encounter a “Page Not Found” error, it means you currently don’t have a (live) robots.txt page.

2. Do I need a Robots.txt file for every subdomain?

Yes, robots.txt files are specific to each subdomain. If your website has multiple subdomains, you should have a separate robots.txt file for each to control the crawling behavior independently.

3. Why does my website need a robots.txt file?

Your website needs a robot.txt file for several reasons. 

• To prevent duplicate content from appearing on SERPs. 
• To specify the sitemap location. 
• To prevent search engine bots from crawling certain sections of the website. 
• To keep certain sections of the website private. 
• To prevent overloading the servers when search engine crawlers load multiple pieces of content simultaneously.
