What is a No Follow Link?
A no follow link is a link that does not count as a point in the page’s favor, does not boost PageRank, and doesn’t help a page’s placement in the SERPs. No follow links get no love. Theirs is a sad and lonely life.
A no follow link is created with the nofollow link HTML tag, which looks like this:
<a href=”http://www.blabla.com/” rel=”nofollow”>Example</a>
The nofollow tag is basically a notice sign for search engines saying “don’t count this.”
Isn’t that just mean and terrible? Why would anyone do such a thing? There’s a reason for the nofollow attribute, and boy is it a good one!
