Their goal is to become the go-to brand for consistency in fits, sizes, quality, and availability. How to communicate to and with their audience segments was one of the main obstacles in the start-up phase of KING Essentials. KING Essentials didn't have much online advertising experience on board, and decided to work with Marveltest. Their decision was based on the experimental framework ideas we suggested. We've setup a complete online marketing infrastructure for KING Essentials. From the beginning we composed a strategic performance marketing fundament. Extended Data visualization dashboarding resulted in a sophisticated multichannel market approach from the start. The cooperation with KING Essentials came about to support them in speeding up the concept validation process. After 6 months of collaboration and several advice reports, KING Essentials was able to move on with a clear market approach.
