Justtag Group
We precisely measure the ROI from the digital campaign and maximize its effects in online and offline channels. We provide the necessary knowledge, measure the effectiveness of activities and help attract new customers to stationary and online stores. The Justtag Group is part of the Dirlango Group. As an umbrella brand, it covers three groups of services - KoalaMetrics, Audience Solutions and JustWifi. KoalaMetrics precisely analyzes the location of smartphone users with the Android operating system (micro-location), based on nearby wi-fi networks. This allows an anonymous and GDPR-compliant way to identify user behavior patterns and create their detailed Offline Profile (a set of assigned Offline Behavioral Segments). Audience Solutions enables a wide analysis of online customer behavior. We use such data to target campaigns even more precisely, to study attribution in detail and build Online Behavioral Segments. JustWifi is a service that allows you to reach target groups with your advertising message via public wi-fi networks.
