I am creating a page for my website. I am adding resources/links to the page. I have to decide if such links will be follow or nofollow and I thought that adding an outbound dofollow link will not bring me any advantage, but only problems because if one day the website I am linking to will became a bad website I will have problems with google. So my questions is: what is the advantage of adding a dofollow external link vs nofollow external link?
