CPA Offer
The most common way to make money on the net is via affiliate marketing whereby you promote someone else ‘s product through your own website and receive a reasonable commission if a sale is made.
With CPA (Cost Per Acquisition) you get paid for leads, not sales. The commissions on the main are lower than affiliate ones, typically between $1 – $6 as opposed to $30 – $40. However some CPA commissions can be extremely high for health, mortgage and insurance markets and the traffic/ conversion rate is very much better.

Affiliate Offer
Anybody, and his dog, can sign up to Affiliate offers but CPA networks are a lot fussier and will actually call you up and quiz you as to your competence for promoting their offers. On the whole, CPA offers look much more professional than most affiliate ones and get straight to the point therefore converting better
Whatever you promote on the net only two things matter – Traffic and Conversion and thereby hangs another tale.
