All CPA marketers put their eggs in one basket. I’ve seen plenty of the greats go from zero to hero and vice versa several time in their careers.

The risk and loss are shared between the affiliate and the advertiser.
Our best performing landing page falls into category C of your poll (50-100K per year). Again, that is just one landing page of hundreds.

One way to fix this is to re-adjust commissions each year,” she explained.
