I'm definitely impressed with Adzzup especially considering the amount of money I spend with them, which is not a lot. I have spent more money on a campaign with Yodle/Outrank who are supposed to be a bigger company but doesn't half way compare to the results Adzzup produces. I am cancelling my account with Yodle and investing that money into improving my campaign with Adzzup and I'm not even worried about it because I already know their program works.
