In this model, you take some fraction of the lifetime value of each customer and plow that back into paid acquisition through SEM, banner ads, PR, affiliates, etc. The spread between your LTV and blended CPA determines either your profitability or your rate of growth, and a high valuation depends on balancing these two factors.
