Lets say you want to link to someone but dont wanna give link juice away.
Google says,....use a rel=nofollow tag in the outgoing link to prevent link juice away...your saying to google...i dont trust this link.
But now if you do....you give link juice away....just see here for more info.

I did never use a nofollow tag....but use a redirect script instead.
this was a simple php redirect like this.
<?php
header("Location:
https://www.linkedsite.com");
?>
But not so long ago...google shows now a backlink given over this script to some of the sites i link to.... meaning link juice wil flow from me to them.
I now changed it to a good old javascript in the page with a noindex, nofollow inside the html head.
I know many people will use the header tag in php....but be aware that google is now following them.
Also....google does now read javascript as text.....and can read and follow links which are written in full inside the javascript file....be warned to verify this as you might loose a lot link juice.
