Be Aware of rel="nofollow" for Links
Setting the value of the "rel" attribute of a link to "nofollow" will tell search engine that certain links on your site shouldn't be followed or pass your page's reputation to the pages linked to. Nofollowing a link is adding rel="nofollow" inside of the link's anchor tag.
<a href="http://untrusted site"rel="nofollow">Untrusted site</a>
If you link to a site that you don't trust and don't want to pass your site's reputation to, use nofollow.
