Prospecting creates the demand
Prospecting is where real growth comes from: new customers who'd never have found you on their own. nCAC is highest here, because cold customers are the most expensive to convince. But it's also the only channel that expands the customer base rather than harvesting the existing one.
Because prospecting feeds the demand that retargeting and brand searches later take credit for in attribution, it's systematically undervalued by last-click thinking. Steer it on MER and incrementality, not attributed ROAS. Otherwise you cut into the very engine that drives everything else.
Frequently asked questions
Why is prospecting more expensive than retargeting?
Because you're paying to convince cold people who don't know you, instead of harvesting warm demand that's already interested. In return, prospecting is what creates new customers and the demand retargeting lives off.
How do I measure prospecting correctly?
On MER and incrementality rather than attributed ROAS. Attribution credits the lower-funnel channels for sales prospecting actually set in motion, so last-click undervalues prospecting's worth.
