The challenge was to increase the number of messages exchanged between online buyers and sellers as well as to split the advertising campaign into mobile and desktop channels.


RTB House recommended its personalized retargeting solution dedicated for well-established e-commerce players. The company prepared various retargeting scenarios adjusted to client-specific goals. This allowed highly tailored creatives to reach individual web users real-time, based on their unique product preferences and search history.
