The micro-vs-macro debate misses the point — both work, for different objectives. Micro influencers (10K-100K followers) deliver high engagement rates (3-7%), authentic content, and the best CPM economics. Macro influencers (500K+) deliver raw reach, credibility, and brand-association lift that micro creators can\'t match.
The math here helps you allocate. Per $1,000 of spend: a micro creator at $500/post produces 2 partnerships × ~5% engagement on say 50K followers = 5,000 engaged impressions. A macro at $5,000/post produces 0.2 partnerships × ~1.5% engagement on 1M followers = 3,000 engaged impressions on this dollar slice — fewer, but with celebrity endorsement value.
Most successful influencer programs run a portfolio. Micro for conversion volume (15-25 partnerships for the same budget that gets you 1-2 macros). Mid-tier (100K-500K) for the sweet spot of reach and engagement. One or two macros for top-of-funnel awareness. Picking just one tier limits the program\'s full impact.

Frequently asked questions
What size is "micro" vs "macro"?
Nano: under 10K followers. Micro: 10K-100K. Mid-tier: 100K-500K. Macro: 500K-1M. Mega/celebrity: 1M+. Engagement rate decreases as follower count rises — micro influencers typically have 3-7% engagement; macros under 2%.
Which tier delivers best ROI?
Micro typically wins on CPM and engagement-per-dollar. Macro wins on raw reach. The strategic question is what you're buying: micro for conversion-driven campaigns and authentic content; macro for awareness lifts and brand association.
How are influencer rates priced?
Industry rule of thumb: $100 per 10K followers per Instagram post. So a 50K-follower creator is ~$500/post. Adjustments: TikTok 50-70% of Instagram rates; YouTube 2-3× IG (more production value); Reels 80-100% of IG; Stories 30-50% of IG.
Should I pick one tier or mix?
Mix. Most successful influencer programs run 70% budget on micro/mid (10-20 partnerships) and 30% on macro (1-2 high-profile placements). The micros drive conversion volume; the macros drive credibility and audience signal.
What's a sustainable ratio of paid vs gifted?
For brand-building: 70% paid partnerships, 30% gifting (seeding). For pure DR: 90% paid, 10% gifting. Pure gifting works only for hot launches with media tailwind.
