Smaller creators typically cost less and convert better than large ones, because their audiences trust them and the categories are narrow. The catch is arithmetic: reaching the same audience takes many partnerships, and every one needs finding, briefing, contracting, checking for disclosure and paying. The coordination is the cost, and it is what the agency is really for.
The economics are coordination, not fees
Twenty small partnerships cost twenty times the administration of one large one, at a fraction of the creator fee. That is why these programmes are priced on management rather than on media, and why an agency's process and tooling matter more than its roster. Ask how many partnerships one account manager handles.
Disclosure at volume is a process
A material connection must be disclosed clearly on every post, gifted product included, and the advertiser is expected to monitor rather than delegate. Across many creators that means a briefing template, a check on every post and a record of it. This is the obligation most likely to be neglected as a programme scales.
Briefing without scripting
Small creators work because they sound like themselves. A brief that dictates wording produces posts that read as advertisements and lose the advantage you were buying. State what must be included, what may not be said, and the claims that are off limits, then leave the voice alone.
Measure the programme, not the posts
Individual small partnerships produce small numbers and the programme produces a pattern. Track code and link performance in aggregate, branded search movement during flights, and repeat purchase from customers acquired. Judging each creator on their own post leads to cutting exactly the long tail that made the economics work.
Questions people ask about agencies for micro influencers
How many micro creators does a programme need?
Enough for the aggregate to be readable, which is usually more than a first budget assumes. Too few produces noise rather than a result.
Does gifted product need disclosure?
Yes. Receiving free product is a material connection and must be disclosed even with no payment and no obligation to post.
How should the agency be paid?
On management rather than a percentage of creator fees, since the work is coordination. A percentage of a small fee pool cannot fund the administration the programme needs.
