What is a Backlink? Why Backlinks are Important?

A backlink is a hyperlink that comes from one page to another page. These hyperlinks are basically incoming links to a webpage from an external website/webpage. A backlink is a very essential aspect of Google Search Engine. When you get the incoming links from external pages Google believes your content is trustworthy.

To understand backlink, let’s consider I have a webpage called (page 1) and inside that, there are a couple of external links pointing to some other page of another website.

Now assume you have a webpage too called (page 2) which was the page I have mentioned from my page with a hyperlink. In this scenario, you can say “yes my page (page 2) has a backlink from (page 1).

Backlinks can help in boosting web pages rank higher on Search Engines. High-quality backlinks drastically increase the visibility of a web page and improve the domain authority. It is a critical part of your website’s overall growth.

Technically there are two types of backlinks when an author or publisher adds HTML links to mention a specific page.

  • Dofollow backlink
  • Nofollow backlink.

A dofollow backlink basically is the one that has the ability to pass link juice to the destination page by commanding the Search Engine Bot to follow the link. 

Dofollow links are recognized by the rel attribute which is used to define the type of links. So a dofollow link can be written as,


Remember: If a link does not have the rel attribute then it’s considered as dofollow link.

In the opposite way, a nofollow link attribute does not allow search engine bots to follow the link.

That means if the website owner is linking back to you with nofollow attributes, it does not pass on link juice. So basically only a human who is reading that page can read or follow that link.


Since nofollow links are not going pass link juice they are not going to help in ranking. They are just a link to another URL where you may find some useful information related to the current page topic.

While viewing a page without knowing what’s the internal HTML has you could be confused about how to know what is a backlink type.

Since you know the structure of links inspecting a page can tell you a link inside a page is dofollow or nofollow.

You can have a look at the page source instead inspect the page to find the hyperlink type.

If the HTML doesn’t include the rel attribute you should figure out that it’s a dofollow backlink.

Else look for the “dofollow” rel attribute.


in terms of the nofollow link, you can find the nofollow attribute in the hyperlink HTML,


Another option is to use the “Strike Out Nofollow Links” Chrome extension.


This extension automatically puts a line through over any nofollow links on a page. See the example below.

Let’s understand one thing since the nofollow backlinks don’t pass link juice it doesn’t boost your page rank by any means. However, it still can provide your page human visitors who are interested in the content.

Now the dofollow backlinks are important for your site’s technical growth. Because they pass link juice it will benefit your site by increasing the power or trust of the page in search engine’s eyes.

The basic concept is simple, you can assume each dofollow backlink as a trust point towards your page that helps you to go up the word in Google’s ranking algorithm.

When a web page is linked by other web pages then search engines consider it as a high relevancy web page that means your content may be trustworthy.

The importance of creating backlinks in SEO to boost organic traffic on your web pages. So basically it will bring more people to your website from an external page and organic search as well, definitely a win-win deal.

Not all dofollow backlinks are the same or good to be linked with. High-quality backlinks are those which come from authoritative sources. While some low-quality backlinks may make detrimental effects on your site which eventually leads to lower your domain authority.

You can find your backlink quality by collecting the link toxic score which is basically a matric that calculate the probable risk of incoming link from 0 to 100 where lower score determine safe linking.
