Rosental’s Journey

As an aspiring leader in natural skincare, Rosental continuously innovates to align beauty with science. However, the brand needed a solution to continue its rapid growth by activating new customer segments across all networks more effectively.
Acquiring new customers has become increasingly challenging due to the rise of automated ad placement technologies like Performance Max (PMax) and ASC. These technologies make it difficult to actively tap into new customer segments, especially when scaling ad campaigns on major platforms to mid-size six-figure monthly budgets. Rosental needed a smarter, data-driven approach to sustain growth.

The Innkeepr Moment

Recognizing the potential of turning anonymous visitors into highly relevant customer segments, Rosental turned to Innkeepr. Unlike rule-based audiences, Innkeepr’s predictive audiences dynamically assessed user behavior to determine the highest-converting prospects on an individual campaign level.
Through this AI-powered approach, Rosental could bridge audience gaps left by cookie deprecation and privacy updates, while sustaining ad campaigns with fresh and highly relevant audience segments. Within weeks of implementation, they saw significant performance improvements, validating the power of AI-driven targeting.

How Rosental Uses Innkeepr

Innkeepr’s audience building engine seamlessly integrates with Rosental’s advertising stack, enabling:

  • Real-time audience updates: Identifying and targeting users with impact ad campaigns across platforms.

  • Automated spend protection: Reducing inefficient ad spend while eliminating likely non-purchasers through intelligent exclusion lists.

  • Incrementality insights: Unlocking profitable growth with campaign-tailored seeds on paid social and SEA.

Scaling Profitable Ad Campaigns

Since adopting Innkeepr, Rosental successfully scaled its social advertising efforts. The AI-driven targeting not only helped scaling performance spends but also tapping into new customer segments more effectively. The result? Sustainable growth and a competitive edge in the evolving skincare landscape.
