Find a high-velocity (or high-"gravity") affiliate product. (That's how you know there's a market.)
Build a quick-and-dirty little value-add, which you offer for free behind a contact squeeze.
From the squeeze, resolve to the product page via your aff link.
Buy keywords for and closely related to the main aff product name. Engage in other
sneaky and not sneaky marketing tactics to build traffic.
Market other targeted aff products to the e-mail list you generate.
Rinse and repeat.
