On one of the free web hosts I run I had a cz.cc free domain ad, only on 1 page. In the same period I had a bidvertiser ad on every page of three websites that made 2 cents less than the cz.cc ad. There was 1 conversion per week for the cz.cc ad and 1 click biweekly on the bidvertiser. Now I have replaced the bidvertiser with the cz.cc ad and a cz.cc ad. Also in the rotation is a namecheap ad.
