What is the Importance of Backlinks for SEO?

Backlink is a very important factor for search engines to find out how popular is a website or how much authority a website has to rank any article. Well, you will find many articles, discussions where nobody will 100% say that backlinks are important.

But the truth is quality backlinks are always necessary and you must know how to find out relevant websites to create backlinks for your website. And these paid & free backlink checker tools will help you to find out the websites where you can make backlinks.

Types Of Backlinks

When we talk about off-page SEO, backlinks are the major roles to play. If you don’t know how many types of backlinks one website can get, then you can’t understand the efforts you need to provide to make a quality backlink profile for your website. So here are 2 different types of backlinks you must know.

  • Dofollow Backlink: This is the most important type of backlink. When a website give a dofollow backlink to another website it actually passes the link juice to the other website. This is a positive signal that Google consider as trust factor. With more dofollow backlinks one website can gain a huge trust authority in the eyes of search engines and the articles of that website will start ranking high. So make sure to create or earn dofollow backlinks as much as possible.
  • Nofollow Backlink: This type of backlink is exactly the opposite of dofollow backlink. That means Google doesn’t consider them for ranking. But this is not 100% true. Nofollow backlinks are also very powerful when they come from high authority websites. And most importantly, with both dofollow & nofollow links one website can make a better backlink profile. So make sure to create both types of backlinks otherwise a website with 100% dofollow backlinks will always look like spam.

Besides that there are various methods to create backlinks like using profile creation sites, forum submissions, social bookmarking, guest posting and many more. One must give enough time to learn the methods and create backlinks gradually.

Why you need backlink checker tools?

Well, we got the importance of creating backlinks. Now the next question is how to know the list of websites where we should create backlinks?

If you don’t know then let me tell you that, you must take care of the websites where you are going to add your website. Because a wrong backlink will hurt your website also. So you need to consider various things like:

  • The Authority Of the website
  • The spam score of the website
  • Link relevancy
  • Placement of the link
  • Anchor text of that link

Now, how exactly you will know all these factors before creating backlinks for your website? That’s where the importance of the backlink checker tools. With those tools one can analyze any websites in just few seconds, find out how your competitors are creating backlinks and exactly replicate the same.
