HLK partnered with Ameren Illinois to launch a two-phase, full-funnel multimedia campaign that boosted awareness and enrollment in energy-saving programs. By segmenting audiences into five personas and leveraging a mix of paid search, social, video, and retargeting, we delivered personalized, actionable messages that resonated. The campaign drove over 30,000 landing page views — a 1,500% increase — and significantly improved adoption rates for Ameren’s most valued services.
