Where did you get the vouch for free? it is from op sell? If yes i think the op offer is not profitable...
The profit is largely based on keywords as well. The keywords for this vouch service site was not provided. Therefore the keywords was his domain name which was not even a word.. It was four letters with 1 number.
It is advised that you check the keyword-price list or alternatively, you can post a content on your site with good keywords and directly lead visitors to your posted content with adsense integrated
