Challenge
LILLYDOO had grown into Spain, France, and Italy and wanted to keep expanding with paid social. With Advantage+ Shopping limiting classic targeting, reaching new high-intent families got harder.
Solution
Use Innkeepr to analyze LILLYDOO’s subscriber base, build Seed Signals from the patterns of high-intent users, and use them for Meta campaigns across all markets.
Results
Cost per acquisition 11.7% lower.
71.1% of ad spend now runs on Innkeepr signals.
Seed Signals in use across all European markets.
A European baby care brand built on subscriptions
LILLYDOO makes skin-friendly diapers and baby care products, sold by subscription across Europe and in drugstores. Paid social on Meta is a key growth channel. With Innkeepr, LILLYDOO uses its own subscription data to reach families who are likely to subscribe.
Classic targeting stopped working
As Advantage+ Shopping took over more of Meta’s targeting, interest-based audiences lost their effect. LILLYDOO needed a way to bring its own first-party data into the platform and steer spend toward people likely to subscribe.
Seed Signals from the subscriber base
Innkeepr analyzed LILLYDOO’s existing subscribers and identified behavioral patterns that indicate purchase intent. From these patterns, Innkeepr built Seed Signals that LILLYDOO uses as the source for Meta lookalikes in every market. The signals refresh automatically, so the audiences follow changes in behavior without manual updates.
“With ASC restrictions making traditional targeting less effective, we needed a solution that could work with first-party data. Innkeepr’s predictive audiences gave us exactly that.”
