I am going to tell you why is it better to choose a payday international affiliate network over the other network selling stuffs like medicines and what have you.
The reason is simply because there are not many people out there on the Internet looking for things to buy when they are searching information. You may get lucky and managed to seal one or two and profit from the sales by getting your cut of the commissions. But is it viable? It is certainly not.
Most often than not, apart from dating services affiliate, the most lucrative affiliate program would be those that offers payday loans. Why is that so? Just look at the economy, it is crashing everyday. During the week when this post is made, Dow Jones Industrial Average Index ended its week deep in the reds and it is now nearing the Nov 11 level. The market rally beginning in Jan 12 till Apr 12 is completely wiped out.
Economy as volatile as this is no coincidence. Unemployment rates are rising everywhere in the world. Development countries have trouble having positive GDP and Europe is in deep trouble, both financially and politically.
People get attracted to advertisements that provide loans and especially those top affiliate networks. People needs money and that is an international fact. Some network would pays you based on clicks and some pays you based on the number of sign-ups made. There are some network pays you for both a stipulated rates. Search around and I am sure they are not difficult to find.
There is actually no harm sparing one or two notable space for such advertisement banners or so. Just try placing some payday affiliate network ads and see the result for yourself now.
