What a micro-influencer is

A micro-influencer is a creator with a modest, niche-focused following — most industry definitions put the band somewhere around 10,000 to 100,000 followers, though the cutoffs are conventions, not standards. Below them sit nano-influencers; above them, macro- and mega-accounts. What defines the tier in practice is less the number than the relationship: micro creators usually occupy a specific niche — vegan meal prep, trail running, indie game development — and their audience follows them for exactly that.

Why brands work with them

Published studies have generally reported that engagement rates decline as accounts grow, which means micro accounts often deliver more interaction per follower than celebrity-scale ones. They are also dramatically cheaper, frequently open to product-for-post or modest fees, and their niche focus makes audience targeting almost automatic — a hundred thousand strangers matter less than ten thousand people who care about your exact category. Their recommendations tend to read as peer advice rather than celebrity endorsement.

A concrete example

A brand with a €3,000 budget books ten micro creators at €300 each instead of one large account at €3,000. Each micro account averages 25,000 followers and a 4% engagement rate — about 1,000 interactions per post, or roughly 10,000 across the campaign, spread over ten distinct niche audiences. The same budget on one big account buys a single audience and a single creative gamble; the micro route diversifies both.

How to vet and work with them

Check engagement quality, not just rate — real comments from real profiles, not walls of emoji. Ask for audience data to confirm geography and demographics match your market. Keep briefs loose, require disclosure, and give each creator a unique code or link. Many brands treat micro campaigns as auditions for longer ambassador deals: the creators whose numbers work get renewed.
