The term dofollow link was introduced in 2005 by Google, to reduce the search engine spam indexing and to improve the search engine results. Only Dofollow links pass link juice to the linked webpage and influence the target’s page rank.
How to identify dofollow link?
For identifying it, you don’t require any advanced coding knowledge. Simple basic HTML can help you regarding the same. Link ‘rel attribute‘ defines the type of link and by checking this attribute you can very well judge whether it’s a dofollow link or nofollow link.
<a href="http://exampledemo.com" rel="dofollow">Example1</a>
<a href="http://exampledemo.com" rel="external">Example3</a>
Rel Dofollow – All three above links are dofollow, which means if a link doesn’t have a rel attribute then it’s a dofollow link. On the other hand, a nofollow link must have been marked as REL No follow tag.
<a href="http://exampledemo.com" rel="nofollow">Example4</a>
<a href="http://exampledemo.com" rel="external nofollow" >Example5</a>
Both the above links are nofollow. For them the Rel tag should be set as “nofollow”.

Multiple Dofollow links from same webpage
If multiple links are pointing to the same webpage then Google bot considers the first link and ignore others. So if a webpage has two links pointing to same page of other website and out of 2 links, first is nofollow and 2nd one is dofollow then Google bot consider the first link and ignores second one, so in such scenario dofollow link gets ignored by bot and no link juice passed. The same rule applies for internal links too.
