Hello,
A lot of people think that the only links that count are the “Follow” designated kind. That is not really true though, as because all links can create traffic, as long as the links are viewed by website visitors. While it is true that “nofollow” links will not pass any “PageRank” or value on to the receiving website, they do create visitors for the website though. The more visitors you have, the more chances you have to create conversions and increase profits.
For some great information expanding on this concept, here is a link to a great article on MOZ.Com about it.
