Case Study: Erwin Penland achieves 19% more conversions and 27% lower cost per conversion with Google Analytics Solutions

Google Attribution 360 lets Erwin Penland see holistic marketing impact

Erwin Penland, a Greenville-based agency, was working with payday lender Advance America to grow acquisition without increasing media spend. The agency needed to move beyond last-touch measurement, optimize media buys, and squeeze more conversions from existing budgets while lowering effective cost per conversion.

Erwin Penland implemented Google Attribution 360 to get a holistic, cross-channel view, identify non-viewable and poor-performing placements, eliminate audience overlaps, and apply data-driven frequency caps and placement moves. The optimization delivered immediate gains: 19% more conversions on the same budget and a roughly 27% reduction in overall cost per conversion (with eCPA improvements of 14–20% in the first three months).
