Do Follow
The “do follow” (also “follow”) attribute means that the link can pass “authority” and PageRank from the source page to the target page.
Technically, it is a value assigned to the rel attribute of a link in HTML. By default, all links are dofollow unless a “nofollow” attribute is added, which tells search engines not to follow the link.
Theoretically, adding (leaving) the follow attribute means conveying a vote of confidence for the information shared on the target web page, which Google considers as a ranking factor.
