Why Robots.txt is important

Robots.txt file is not important for all websites, especially small websites. But it doesn’t mean you shouldn’t have one. Having a robots.txt file gives you more control over how search engine crawlers should crawl your website.

1. Preventing Indexing of less Important pages or (Resources) 

With the help of robots.txt, you can prevent crawlers to crawl some web pages on your website and you can also use it to prevent Indexing of your multimedia resources.

2. Utilize Crawl Budget

If all important pages of your website are not getting indexed then it may be happening because of the crawl budget. With the help of robots.txt, you can block all the unimportant pages of your website so that search engine bots like Google or Bing bot spend more time on important pages of your website.

3. Block Pages that are not important for users

Lots of times we have some pages on our website that contain sensitive content or have content you think is not important for users then you can block them by using robots.txt. 

For example, if you have a login page then these types of pages have to exist you don’t want to index them so in this case, you can use robots.txt to block this page for crawlers.

Robots.txt Syntax 

There are 4 common terms that you will see in a Robots.txt file. 

1. User-agent:

A specific crawler or a Search Engine to which we give instructions.

2. Disallow:

It is instruction or command that we use to tell search engine crawlers to not crawl a particular page.

3. Crawl delay:

It is a command that we give to the crawler to how many seconds a crawler should wait before crawling the web page. (Googlebot does not follow this command) 

4. Allow:

It is a command that instructs Google Bot to crawl a web page even if its parent page is disallowed. It is only applicable to Googlebot.

How to find the robots.txt file

If you want to know that is your website has a robots.txt file or not you can check that by using this yourdomain.com/robots.txt.

Here replace yourdomain.com with your website URL and search it on any web browser after that if you get a file like in the picture then it means your website has a robots.txt file.

If you don’t have a robots.txt file then you can easily create one for your website. To do that first open a new .txt file now start typing 

user-agent: *

Now if you want to disallow your admin directory for all crawlers then type 

Disallow: /admin/

Once you have done that your robots.txt file will look something like this.

Where to upload your robots.txt file

To upload robots.txt open the c panel of your Hosting then go to file manager. The next step is to find the public_html folder then here upload your .txt file.

After finishing this process you can check your robots.txt file by searching yourdomain.com/robots.txt in the search box of web browsers. 

If you want to upload a robots.txt file for your subdomain then upload it to the root directory of your subdomain. To access robotos.txt of your subdomain then type blog.yourdomain.com/robots.txt in the search bar of web browsers.

Best Practices 

Here are the things you should avoid while creating robots.txt.

1. Use Wildcards

Use wildcards (*) to apply instructions to all user agents and you can also use them to match URL Patterns when declaring directives. 

2. To specify the end of the URL use “$”

To specify the end of the URL use “$” 

Ex. If you have lots of PDF files on the website and you don’t want search engines should index them then you can add this syntax on the 30th of our robots.txt file.

User-agent: *

Disallow: /*.pdf$

So with this search engine can’t access any URL ending with .pdf.

3. Use Comments to explain your robots.txt file to humans

With the help of comments, your team or developers can understand your robots.txt file. To add comments to your file just start the line with a hash (#).

All crawlers will ignore all lines that are starting from #.
