Short version. A follower of a 10,000-follower account has usually met the creator, or feels they have. The recommendation lands as advice, not advertising.
Why micro works
A follower of a 10,000-follower account has usually met the creator, or feels they have. The recommendation lands as advice, not advertising. Conversion rates on micro accounts are routinely several times those of celebrity accounts; the trade-off was always reach per account, and the way to get reach is many accounts — which is an operations problem, not a marketing one.
The operations problem, solved by the reward
With a per-result reward there is nothing to negotiate per creator. The reward is on the offer; the budget is locked; the platform pays as results land and shows every creator their own numbers. Your job becomes choosing the reward and reading the results, not managing fifty invoices.
What to pay a micro-influencer
Start from what a result is worth to you and pay a fraction of it per result — the platform's floors by ticket size (₹20 for sign-ups, rising with the order value) are the least creators take an offer at. If you do not know the rate, switch on automatic reward and read the history after a week.
