Brand love was first studied scientifically 20 years ago but is still not fully understood. The first researcher to empirically study brand love, like love for people, was Aaron Ahuvia in the early 1990s. His work found brand love is based on trust, and trust is triggered by brands that demonstrate accountability, reliability, transparency, relevancy, and innovation. Beloved brands earn customer trust through these five attributes, driving loyalty, positive word-of-mouth, and willingness to pay more.
