Rising CAC is the biggest threat to D2C profitability. We identify the specific inefficiencies — creative fatigue, poor landing pages, weak post-click conversion, mis-allocated media spend — and fix them to deliver more customers for the same budget.
The most common causes are creative fatigue (same ads for too long), audience saturation (exhausted your addressable market), increasing platform competition, poor post-click conversion and inaccurate attribution leading to misallocation.
Brands with significant creative, landing page or attribution issues often achieve 20–40% CAC reductions through focused optimisation. Diminishing returns apply once the major inefficiencies are resolved.
New creative — fresh hooks, new angles, different formats — has the fastest impact on CAC for brands experiencing creative fatigue. CRO improvements on high-traffic landing pages are the second fastest lever.
We use new Customer Acquisition Cost (nCAC) — the cost to acquire a genuinely new customer — rather than blended CAC, which includes returning customers and consistently underestimates true acquisition costs.
Pausing is rarely the right answer. Pausing breaks algorithm learning, loses audience momentum and is typically far more disruptive than fixing the underlying issues while maintaining spend.
