In the html tag if I don't include 'rel' attribute, how will be the link interpreted by search engine?
Would it be considered as a dofollow link or nofollow?
<a href="http://www.example.com">Example link</a>
Unless rel="nofollow" is specifically assigned to a link, it is considered follow by default, no need to assign rel="follow" - (dofollow is not a valid value)
