Many of you have already heard of Social Monkee, however for those who have not let me fill you in. Social Monkee is a free service that provides you with 25 unique backlinks to your site. You can either submit your site using the Social Monkee site or download the Social Monkee Firefox plugin.
I have spoken with a few people about Social Monkee and most seem to think it is a good deal. I have been using it for a short time now and intend to write a full review after I have used it longer. It is easy to use and yes it is free.
There is an upgrade option if you choose, it is a one time 47.00 dollars. However, it gets better, if you refer 12 people you get upgraded automatically. When upgraded you have access to more features and get 100 unique backlinks.
It is well worth trying if you are tired of trying to generate more and more backlinks. You can sign up for your free Social Monkee account here.
