A staggering 87% of ecommerce founders are wasting money on ads due to poorly executed marketing campaigns. Many invest heavily without a clear strategy, targeting the wrong audience, using weak creatives, or failing to optimize their campaigns based on performance data. Effective ecommerce marketing campaigns require more than just ad spend—they need strategic planning, proper funnel setup, and consistent analysis. Without these elements, ad budgets are quickly burned with little to no return. Understanding where most founders go wrong can help you avoid common mistakes and build campaigns that actually convert and scale profitably in today’s competitive ecommerce landscape.
