Do not pay any money for this. First of all, they don't offer any trial or money back guaranteed. That should have made me stay away but i've read all the great reviews. I eventually paid and signed up. Never got a confirmation or anything. I started using the tool but it never got any good results. Links were totally irelevant and their quality was really poor (as graded by the app itself). It was nothing like in the reviews or like in the marketing lies on their website. Wasted money.
