Paid Acquisition

Paid acquisition

Paid channels buy attention at auction, which means costs rise until marginal buyers are unprofitable. Discipline comes from knowing what a customer is worth and refusing to pay more, which requires unit economics before the first campaign.

Method

1. Know your allowable acquisition cost first. Derived from contribution margin and payback period, since without it there is no basis for deciding a bid is too high (see unit-economics).
2. Start with the highest-intent channel. Search captures existing demand and converts far better than interruptive channels that must create it.
3. Match the landing page to the ad. A mismatch between promise and page is the most common and most expensive conversion leak (see landing-page-strategy).
4. Measure to the outcome that matters. Cost per activated or retained customer, not per click or per signup, since cheap signups that never activate are a cost.
5. Test creative and audience separately. Changing both makes results uninterpretable, and creative usually matters more than targeting.
6. Expect rising costs and diminishing returns. Scaling spend means reaching less interested people, so efficiency falls as volume grows.
7. Set a kill threshold before launching. The spend at which an underperforming campaign stops, decided in advance rather than in the moment.

Boundaries

Paid acquisition buys volume and does not create product-market fit; scaling spend on a leaky funnel accelerates loss. Attribution is imperfect and platform-reported conversions are self-graded (see marketing-attribution). Privacy changes have materially reduced targeting and measurement accuracy.
