ARS is a joke as much as Maxcash is, but they still get shit loads of sales, so they must be doing something right.
Look at smaller sponsors like lightspeedcash, triplexcash, etc. they will make you $ on your traffic.
Funnily enough I am 1:10120 for silver cash, and my best sponsor is 1:9 for over 100 sales. just goes to show that some sponsors will never work for you, and some will.
