Influencer marketing uses another person's audience and trust. 1M+ followers — mega-influencer (wide reach, low engagement); 100K–1M — macro; 10K–100K — micro (high engagement, clear niche); 1K–10K — nano (highest trust, local impact).
For smaller brands, micro and nano influencers are more effective — cheaper, more authentic, higher conversion. Contract essentials: content rights, disclosure (showing payment, FTC rule), KPIs (reach, engagement, link clicks, promo code). Influencer authenticity: if they genuinely like the product, results are better.
