Case Study: Erwin Penland achieves 19% more conversions with Google Attribution 360

Google Attribution 360 Lets Erwin Penland See Holistic Marketing Impact

Erwin Penland, a Greenville-based agency, needed a better way to measure marketing performance for client Advance America and move beyond last-touch attribution. With Google Attribution 360, the agency wanted to optimize media spend, increase conversions, and lower costs without raising the budget.

Google Attribution 360 gave Erwin Penland a holistic view of cross-channel impact, helping it identify waste, reduce overlaps, and apply frequency caps more effectively. As a result, Google Attribution helped the agency drive 19% more conversions with the same budget and cut overall cost per conversion by 27%, including a 14% to 20% eCPA reduction in the first three months.
