I needed to diagnose the issue and decide whether to optimize or reallocate the budget.
I analyzed the audience segments and found our targeting was too broad. I narrowed to lookalike audiences based on our highest-LTV customers, refreshed the creative to address specific pain points, and A/B tested landing pages.
