What are the types of backlinks?

Backlinks are of two types "Dofollow" links and "no follow" links. Dofollow links are considered by search engines for accounting the value of domain name. While no nofollow links are not counted for domain authority consideration. Dofollow links from high authority websites add more value to your domain and vise-versa.

It doesn't mean that you remove all nofollow links pointing to your website. If you have many nofollow links from good websites even they do not provide any value but still provide some traffic to your website. Most of the social media sites like Facebook, Pinterest, Reddit provide nofollow links when your share or write any content on them. But experts says that clean up even nofollow links from spammy websites.

The question is how to identify nofollow links. This can be done by viewing the source code of link providing page. No follow links have no follow attributes with them as shown below.
