Why this research matters

Last Click is still common because it's simple and familiar—the data is easy to organize and easy to explain to a colleague.

However, as customer journeys grow more complex and data signals decline, there is a growing recognition around the need for a more holistic approach to marketing measurement, ensuring every dollar in every channel is fairly evaluated against the impact it delivers.

This report seeks to empirically demonstrate the impact of graduating from Last Click measurement to more sophisticated marketing measurement. 

From June 2024 to February 2025, Fospha and Meta Marketing Science partnered to test the impact of moving 6 eCommerce brands from Last Click to Fospha incremental full-funnel measurement.
