Influencer Selection
Brands
There's no single right tier — only the right tier for your goal and budget. Nano influencers (1,000–10,000 followers) offer high trust and low cost but limited reach; micro (10,000–100,000) is the workhorse for most ecommerce brands; macro (100,000–1 million) and mega (1 million+) buy broad awareness fast but are rarely the cheapest route to direct sales. Choose the tier by objective, not by what looks most impressive.
No platform or industry body has set an official line between nano, micro, macro and mega. The boundaries are a convention, and different sources draw them slightly differently. What sources agree on is the order of magnitude, which is what matters in practice.
| Tier | Followers (typical range) | Characteristics |
|---|---|---|
| Nano | 1,000–10,000 | Tight, often local or niche audience. Personal relationship with followers. |
| Micro | 10,000–100,000 | Still niche, but with real reach. Often semi-professional content production. |
| Macro | 100,000–1 million | Broad, often cross-niche audience. Professional production, frequently agency- or manager-represented. |
| Mega | 1 million+ | Celebrities and major creators. Massive reach, very broad — not necessarily relevant — audience. |
Some sources put the micro/macro line at 50,000, others at 100,000 or even 250,000. Treat the table as orientation, not law — and always evaluate the individual profile, not just which bracket its number falls into.
The most consistent pattern across analytics tools and agency reports is that engagement rate falls as follower count rises. Nano and micro profiles typically outperform macro and mega profiles on this measure — but by how much varies enormously by platform, niche and measurement method, so no single universal benchmark figure exists, and any source handing you one precise number deserves scepticism. Treat the direction (engagement falling as followers rise) as the expectation, not the exact figure as fact — and always look at the specific profile's own numbers, as covered in how to spot fake followers. For the exact formula and how to calculate it yourself, see influencer engagement rate: how to calculate it.
Price scales far from linearly with follower count. A macro profile typically costs many times more than ten micro profiles combined — not because the reach is ten times larger, but because the price also reflects production, agency representation and exclusivity. See how much brands should pay influencers for setting a fee that matches the tier.
Macro and mega profiles often deliver more polished content, but with less flexibility: more approval steps, longer lead times, less room to deviate from an established format. Nano and micro profiles are typically faster to work with and more willing to test a new format or message.
A tight, niche audience generally trusts recommendations from the profile they follow more than a broad audience does. That is the commercial logic behind nano and micro influencer marketing: smaller reach, but an audience that actually listens. Whether that trust converts to sales still depends on whether the product and audience genuinely fit — see why influencer campaigns get engagement but no sales.
Tier should follow the campaign's objective — not the other way round. Use this table as a starting point:
| Goal | Recommended tier | Why |
|---|---|---|
| Direct sales on a tight budget | Micro (or nano) | Best balance of cost, reach and conversion. Easier to test with performance-based pay. |
| Broad awareness / product launch | Macro or mega | Reach and exposure fast, when the objective is attention rather than sales. |
| High-volume UGC for paid ads | Nano | Low cost per collaboration leaves room to commission varied content to test in paid ads. |
| Niche market / tight audience | Nano or micro | The audience is already filtered by interest — broader tiers often miss. |
| Testing a new category or market | Micro, many profiles | More independent data points for the same budget — see the worked example below. |
If you don't have a clear objective yet, it's too early to pick a tier. Define the goal first — see how to choose the right influencers for the broader selection process, where tier is only one filter among several.
The numbers below are hypothetical and illustrate only how a budget divides — they are not a claim about expected revenue or conversion, and this is not a real Make Influence customer case.
A brand has DKK 60,000 for a campaign. Three ways to spend it:
None of the three is objectively "right". A is the right call if the goal is pure reach and you already know and trust the profile. B is often the most practical balance for a brand still learning which profiles work. C produces the most data, but costs the most administration time per krone spent.
Whatever the tier, the same logic applies as with any investment: put the entire budget behind one profile, and you carry the full risk of that one decision. If the profile turns out not to fit the product, has an audience that doesn't actually match (see how to spot fake followers), or simply doesn't deliver on time, there is nothing to compare it against. Several smaller collaborations give you a portfolio to learn from — and a basis for re-booking what actually worked, instead of guessing again.
If the budget itself is small — not just the per-profile spend — tier choice is only part of the picture. See influencer marketing on a small budget for a full playthrough of tactics, a decision framework and a worked example built around a tight total.
In Make Influence's experience, betting the whole budget on one tier permanently is rarely the right call. The brands that get the most out of influencer marketing over time typically use macro or mega profiles to build awareness around a launch or a seasonal push, and micro and nano profiles continuously to keep sales moving and to supply the ad account with content. The two tiers solve different jobs — one rarely sells efficiently on its own, the other rarely scales to large reach alone.
Our recommendation for brands starting from zero: begin in the micro tier with 8–15 profiles to build a solid data foundation (see how to choose the right influencers), track every collaboration individually (see discount codes vs tracking links), and calculate ROI continuously so the decision to move up a tier is based on numbers rather than a hunch (see how to calculate influencer marketing ROI).
Which tier makes sense also interacts with which platform the creator is native to, since discovery and audience size behave differently by platform. See TikTok vs Instagram for influencer marketing for that comparison.
Mainly scale and professionalisation. Mega influencers (1 million+ followers) are often celebrities or creators with full agency backing, while macro profiles (100,000–1 million) more often still run the collaboration themselves. Price and negotiation are typically much heavier for mega.
Often, but not automatically. It depends on whether the audience genuinely matches your target customer and product — a poorly matched micro profile can easily underperform a well-chosen macro one. Tier is one filter among several, not a guarantee on its own.
Yes, as a portfolio. One nano profile alone won't reach far, but a group of several dozen together can produce both reach and a large volume of authentic content — if the coordination overhead can be managed.
It's the most consistently observed pattern in the industry, but it isn't a law for every individual profile. Niche, platform and how active the community is also play a role — treat the pattern as an expectation, and always check the specific profile's own numbers.
Often a good idea if budget allows: macro or mega for awareness, micro and nano for conversion and content volume. It does require tracking each tier separately, or you won't know what actually worked.
