You're spot on with your assessment of what happens in the "summer doldrums".
Internet marketing can be very profitable, but like anything else worth doing, it requires WORK.
Ther simply is no free lunch; but the upside of this business, is that you're not outside in the weather, swinging a pick-axe !
If you're going to try this business, be prepared to give it 150% of your effort and diligence and it will pay off.
