Pay-Per-Click Strategy That Cut CAC by 61% for an E-Commerce Brand
Client Type: Rapid-growth direct-to-consumer (DTC) e-commerce retailer

The Challenge
The client was scaling fast and heavily relying on paid ads, but despite large ad investments, profitability was declining. Their PPC campaigns were poorly structured with broad targeting and generic creatives. Key issues included:
