Nutrafol Drives Efficiency with Brand Pulse and Smartly’s AI capabilities
Objective
As Nutrafol scaled its growth efforts, rising frequency and saturation in retargeting and look alike audiences led to overexposure, ad fatigue, and reduced performance. The brand was hitting the same users too often, driving inefficient spend. The goal was to reduce audience saturation and frequency while preserving Cost Per Acquisition efficiency.
Solution
To tackle rising inefficiencies, Nutrafol used Smartly’s AI-powered Platform and Brand Pulse to launch, manage, and continuously monitor campaigns, gaining real-time visibility into key performance metrics like audience saturation and cumulative frequency.
These insights enabled targeted actions that reduced retargeting frequency and saturation while maintaining stable CPA performance and improving overall spend efficiency. A 24% drop in audience saturation meant far fewer users were being served the same ad multiple times, reducing fatigue and freeing up budget to reach new audiences.
