Here is what a basic link looks like:

<a href="http://www.amazon.com" target="_blank">Visit Amazon</a>

This link points to amazon.com and will open in a new browser window when someone clicks the words 'Visit Amazon'.
So, if someone clicks that links, amazon.com will get the link credit.

Now let's add our NoFollow code.

• All I did was add rel="nofollow" within the link with a space before and after the code.
• Be sure to add the space before and after or else you will get an error.
• The position of the code isn't important, but I prefer to place it right after the URL

Just to make sure you understand what is happening, let's quickly break down this link

• href="http://www.amazon.com" ==> This is the link you are pointing to
• rel="nofollow" ==> This is telling Google not to follow the link and factor the pagerank
• target="_blank" ==> This make the link open in a new browser window
