Summary

This episode challenges the common obsession with CPM (cost per mille/thousand impressions) in paid advertising, arguing that it's often a vanity metric that distracts from true performance. Ecommerce operators should instead focus on metrics directly tied to profit and customer acquisition, understanding that a higher CPM can sometimes lead to better overall results. The core message is to prioritize strategic ad spend over superficial cost-per-impression figures.
