Definition
A content creator with an established audience who has the ability to affect the purchasing decisions, opinions, or behaviors of their followers through their content and recommendations. Influencers are categorized by audience size into tiers: nano (1K–10K), micro (10K–100K), macro (100K–1M), and mega/celebrity (1M+). The term is often used interchangeably with 'content creator' but carries a stronger connotation of marketing and brand influence.
