01 — The Challenge

Make the message impossible to miss.

Efferalgan needed strong outdoor visibility around its “ChapChap” positioning, with a campaign capable of reaching large audiences repeatedly across key Kenyan markets.

The objective was not simply to secure billboard space. The campaign needed the right locations, sustained exposure and active media management throughout the 90-day flight.

02 — The Strategy

Build frequency where people move.

KWETU deployed static billboard placements across high-traffic roads, high-footfall environments and strategically important urban and regional locations.

Media intelligence mattered beyond the initial placement. Six billboard sites were repositioned during the campaign in response to updated traffic information and government directives.
