Brand health refers to the overall strength and vitality of a brand in the minds of consumers, measured across dimensions including awareness, perception, emotional resonance, purchase consideration, and loyalty. Within the Brand, Concept, and Messaging research category, brand health tracking provides the qualitative and quantitative foundation teams need to understand how brand positioning is landing, where equity is building, and where it is eroding. Strong brand health research goes beyond survey scores to capture the language consumers use, the emotions they associate with a brand, and the moments that shape their relationship with it. These deeper signals are what allow insights and CMI teams to diagnose problems early and advise on positioning with confidence.
