Micro influencer marketing means working with creators whose audiences are small enough to still feel like a community and specific enough that the fit is obvious. The appeal to a buyer is arithmetic: many smaller creators cost less per post than one large one, and their audiences tend to be more responsive. The cost is operational, because twenty relationships take twenty times the coordination of one, and each one carries the same legal obligations. Those obligations are not vague. The Federal Trade Commission publishes plain guidance on what has to be disclosed and how, and the responsibility does not end with the creator or the agency. This page covers the pricing, the rules and the vetting.
What you are buying, and what it costs to run
The unit economics look attractive and the operating costs are where programmes fail. Sourcing creators who genuinely fit takes real research, because audience size is easy to check and audience relevance is not. Then each creator needs briefing, contracting, product or payment logistics, content approval, disclosure checking, and tracking. Agencies price this in different ways: a management fee per creator, a flat programme retainer, or a percentage of creator spend, and each rewards different behaviour. A per-creator fee rewards volume, a percentage of spend rewards larger payments, and a flat retainer rewards efficiency until the roster grows past what it funds. Ask which structure is being proposed, ask how many creators it assumes, and ask what happens to the fee when the roster changes.
The disclosure rules, stated precisely
The FTC's guidance for social media influencers says a material connection has to be disclosed whenever a creator got anything of value to mention a product, including free or discounted products and other perks, and even where the creator was never asked to post. On placement it is specific: put the disclosure where it is hard to miss and with the endorsement message itself, since disclosures are likely to be missed if they appear only on an about or profile page, at the end of a post or video, or anywhere requiring a click on MORE. Do not mix the disclosure into a group of hashtags or links. In a picture-based post, superimpose it over the image with enough time to read it. In a video, put it in the video rather than only in the description, because viewers may watch without sound or miss superimposed text. In a live stream, repeat it periodically.
Who carries the risk
Brands often assume the creator carries the disclosure obligation and the agency carries the operational one. In practice the advertiser is the party with the most to lose, and the FTC's endorsement guidance addresses advertisers as well as endorsers. That has three practical consequences for a buyer. First, disclosure requirements belong in the creator contract, in specific language rather than as a reference to the guides. Second, someone has to check published content against those requirements, and the workflow should name who. Third, the FTC notes that if posting from abroad, US law applies where it is reasonably foreseeable the post will affect US consumers, and foreign laws might apply too, which matters for programmes recruiting internationally. Ask a prospective agency to show you their disclosure checking process, not just their compliance clause.
How to vet an agency running this for you
Ask for three creators from a comparable programme, then look at their actual posts and check the disclosures against the FTC's placement guidance yourself. This takes ten minutes and tells you more than any credentials slide. Ask how creators are sourced and what the rejection rate is, because a high acceptance rate suggests a list rather than a fit. Ask what content rights you get and for how long, since reusing creator content in paid media is a separate licence and a common surprise cost. Ask how performance is measured and insist it goes beyond impressions to something the business recognises. Where influencer work sits alongside search, buyers usually evaluate it in the same conversation as digital marketing and SEO services, and the same evidence decides both: published pricing, disclosed minimums and named clients.
Questions people ask about micro influencer marketing
Do micro influencers have to disclose gifted products?
Yes. The FTC's influencer guidance says to disclose a material connection if the creator got anything of value to mention a product, including free or discounted products and other perks, and to disclose even if the creator was not asked to post and believes their own view is unbiased.
Where does the disclosure have to appear?
With the endorsement itself and placed so it is hard to miss. The FTC says disclosures are likely to be missed on an about or profile page, at the end of a post or video, or behind a click on MORE, and says not to bury them in a block of hashtags. In video, the disclosure belongs in the video, not just the description.
How should a micro influencer programme be priced?
Common structures are a management fee per creator, a flat programme retainer, or a share of creator spend. Each rewards different behaviour, so ask which is proposed, how many creators it assumes, and what happens when the roster grows or shrinks. Creator payments should be visible to you separately from the agency's fee.
Can we reuse a creator's content in our ads?
Only with a licence that says so. Usage rights for paid media are separate from the original post and are a frequent source of unbudgeted cost. Settle the term, the channels and the territory in the creator contract before the content is made.
