To understand the comcept of do-follow and no-follow links we must first understand how the search engine works.

Now if we look to the no-follow links, actually no-follow is the attribute of a HTML tag called anchor tag, this tag doesn't let the crawler to jump to the link that is linked through this anchor tag, whereas for do-follow link it allows the crawler to jump to the respective page.

When website a gets a link from another site or a page there are 2 ways to linked. The first is Dofollow and the second one is Nofollow. These both do a similar job of linking between to pages or websites. However, there is differences between them, Lets Discuss them!
A dofollow link is a link that helps in terms of SEO by passing the authority of the origin site to the destination site. This passing of authority is called, “link juice.” Acquiring dofollow backlinks will help improve a website’s domain authority, or domain rating, which in turn, helps to improve keyword ranking.
By default, links are dofollow, so there is no need for rel=”dofollow” when linking to a website.
A nofollow link is a link that is not typically used in PageRank calculations. Nofollow links are a way for publishers to tag links so search engines like Google do not count them as points (or votes) to affect the placement of a web page in the search engine results pages (SERPs).
However, nofollow and dofollow links are both important for a healthy backlink profile and can help you acquire targeted traffic from the linked websites. So it’s good to work on increasing both forms of backlinks for SEO and brand awareness.
