How Millenicom achieved 65.7% increase in tracked conversions with Meta CAPI

Millenicom, a leading internet service provider in Turkey, faced significant obstacles in their Meta advertising campaigns that limited their ability to scale effectively. Incomplete conversion tracking due to browser restrictions, low match rates with Meta's audience targeting systems, and limited first-party data utilization were preventing optimal campaign performance and ROI visibility.

The solution was Meta Conversions API implementation with enhanced customer matching capabilities and server-side tracking infrastructure.

Why Hardal?

Millenicom was struggling with limited conversion visibility caused by browser restrictions, ad blockers, and lost data from Safari and privacy-focused browsers. They couldn't capture the full customer journey across devices, resulting in poor campaign performance visibility, suboptimal lookalike audience creation, and difficulty identifying high-performing campaigns for scaling.

Hardal's Meta CAPI solution, implemented by digital agency Optimic, eliminated browser-based tracking limitations and enhanced first-party data utilization.
