Case Study: O2 Slovakia achieves better ad audience performance with Bloomreach Loomi AI

O2 Slovakia Builds Better Ad Audiences With Bloomreach Engagement

O2 Slovakia, a telecommunications company serving 2.3 million customers, wanted to improve its Facebook and Google ad targeting because the audience-building tools in those platforms were too limited to create sophisticated lookalike segments. The company turned to Bloomreach and its Loomi AI personalization platform to better reach the right users with acquisition campaigns.

Bloomreach helped O2 Slovakia use first-party data and real-time insights from Loomi AI to build more accurate lookalike audiences for Facebook and Google ads. In A/B testing, Bloomreach-driven audiences cut cost per page visit by 60% for Facebook Ads, reduced cost per conversion by 37% for Google Responsive Ads, and lowered cost per conversion by 25% for Google Discovery Ads, helping O2 Slovakia significantly improve campaign performance.
