  • Nano KOC: <10,000 followers. Hyper-local, authentic, works for product barter. Best for seeding and trust.
  • Micro KOC: 10,000–100,000 followers. Higher reach, still high engagement (3-4% in beauty/fashion). Best for conversion.
  • Macro/Mega KOL: 100,000+ followers. Expensive, lower engagement per dollar. Not part of “Mass KOC” strategy.
