Influencers, KOLs, KOCs, and Influencer Marketing: Essential Concepts and How to Apply Them Effectively in the Digital Age

Key Concepts

Influencers are individuals who have the ability to impact public awareness, behaviors, or purchasing decisions through the content they create on digital platforms such as Facebook, Instagram, TikTok, and YouTube. Their influence can shape consumer trends, enhance brand perception, and shift audience opinions. Influencers come in various categories, with the most common being:

・KOC (Key Opinion Consumer) KOCs are everyday consumers who influence purchasing decisions by sharing honest and experience-based reviews of products or services. Although they may not have a large follower base, their authenticity and transparency make their opinions highly reliable. Leveraging KOCs in marketing helps brands create more genuine customer experiences and build stronger trust with potential buyers.
