Backlinks or no backlinks that is the question ?

good morning

Yesterday i try a new bingo place i promote only affiliates links i get 105 downloads in less than 8 hours, i try with blog new one no backlinks only 1 clic ??

What's wrong please with some companies affiliates links work very well and others only blogs?
so is it title text or backlinks the most important please
or all ???

thanks hace a nice day
