Definition and Origin of the Term KOL

A Key Opinion Leader (KOL) is an individual recognized for their in-depth expertise and persuasive power within a defined industry. They often enjoy significant respect from both peers and the public, making them influential messengers in marketing contexts.

Over time, the phrase extended beyond healthcare — today encompassing technology, finance, lifestyle, and more — due to its adaptability for niche credibility-driven campaigns.
