Micro vs Macro Influencers: Which Tier Should You Buy?

Micro creators — roughly 10k to 100k followers — usually win on cost per engaged view and give you twenty independent bets instead of one. Macro creators buy concentrated reach in a single moment and a name that opens doors twenty micros cannot open between them.

The choice is rarely settled by which tier performs better per pound. It is settled by whether you can actually run twenty relationships at once without the coordination cost eating the saving.

What each tier is for

Tier definitions vary by whoever is selling you something. These are the bands we use, and the failure mode each one has:

Tier	Followers	What it buys	How it fails
Nano	under 10k	Genuine community trust, cheap or gifted	Reach too small to read a result from one post
Micro	10k–100k	Best cost per engaged view, niche precision	Twenty relationships to run
Mid	100k–500k	Reach with some production polish	The awkward middle — priced like macro, treated like micro
Macro	500k–1M	One big simultaneous moment, credibility	Single point of failure; agents and lead times
Mega	1M+	Awareness at scale, PR value	Rarely justifiable on direct response

The word "followers" in that table is a convenience, not a metric. Buy on median views of the last ten to fifteen posts, because follower counts stopped predicting distribution the moment every platform moved to interest-based feeds. A 40k-follower TikTok account posting into a working algorithm can outreach a 600k account whose recent videos average 30k. Our guide to vetting influencers covers how to pull those numbers before you commit.

The arithmetic that actually decides it

Take a £6,000 campaign budget and price both routes honestly. The figures below are the shape of typical deals rather than a measurement — your category and market will move them:

Route	Deals	Fee each	Plausible median views each	Total views	Rough CPM
One macro	1	£6,000	150,000	150,000	£40
Twenty micro	20	£300	12,000	240,000	£25

Micro usually comes out ahead on paper, and the gap is not the interesting part. Three things matter more than the CPM:

Variance. The macro route is one bet. If that video lands below the creator's median — which happens perhaps a third of the time, because short-form distribution is lumpy — your entire quarter's creator spend is that one underperforming video. Twenty micro deals produce a distribution: two will beat expectations by a lot, twelve will be unremarkable, and the average survives.

Content volume. Twenty deals means twenty assets. If you have usage rights on them, that is twenty creatives to test in paid, which is frequently worth more than the organic reach you bought. One macro video gives you one.

Audience overlap. Twenty creators in the same niche share more audience than you would like, so the 240,000 in that table is impressions, not people. Assume meaningful overlap when you brief creators from one tight community, and spread across adjacent niches if unduplicated reach is the point.

What twenty micro deals cost beyond the fees

This is the line item that turns a spreadsheet win into a real-world loss. Run the clock on one micro deal end to end: sourcing and vetting, an outreach email and two follow-ups, a rate negotiation, the brief, a shipping address chased twice, one or two approval rounds, an invoice, a payout, and a performance number recorded afterwards.

Call it 60 to 120 minutes of coordinator time per creator across a campaign, once nothing goes wrong. At twenty creators that is roughly three to five working days. Add product cost and shipping — twenty units of a £30-cost product is another £600 plus postage, money that never appears in the "fees" column.

So the honest comparison for that £6,000 is: one macro deal at maybe four hours of work, against twenty micro deals at four days of work plus £700 of product. Micro still usually wins, but only if the per-creator admin is genuinely cheap. When it is not, brands quietly drift upward in tier — not because macro performs better, but because one invoice is easier than twenty.

That drift is the problem CreatorCast exists to remove: outreach runs from your own inbox with replies landing against each creator's record, deal terms sit as structured fields rather than prose in a thread, and approvals and payouts close the deal out in the same place. When twenty deals cost about what five used to, the tier decision goes back to being a marketing decision instead of a staffing one.

When macro earns the premium

There are cases where the concentrated buy is the correct one, and pretending otherwise is how brands under-invest at the moment it counts:

• A launch that needs simultaneity. Twenty micro posts trickling out over three weeks do not create the impression that something is happening. One macro post on day one, with micro underneath it, does.
• Category entry and credibility. A recognisable name attached to your product changes conversations with retail buyers, press and other creators. That value is real and does not show up in CPM.
• Broad consumer categories. If your buyer is "most adults", niche precision is worth less and raw reach is worth more.

Price the friction in too. Macro deals usually run through an agent or a management company, take four to eight weeks from first contact to live, come with exclusivity demands, and carry usage-rights costs that can exceed the base fee. Budget the calendar, not just the money — our usage rights guide covers what the uplift should cost.

A split that survives contact with a real budget

For a brand's first two or three quarters of creator marketing, a workable starting allocation is 70% micro, 20% mid-tier, and 10% held back for one macro or mid test. Not a law — a default that keeps you learning while limiting the damage from any one deal.

Then let the data move it. After two campaigns you will have a cost per attributed order by tier, plus a subjective read on which creators' content actually performed when you put spend behind it. Reallocate toward the tier that won on both, and be prepared for the answer to be unglamorous: for most direct-response programmes it is micro and mid, and the macro line item survives because someone senior likes seeing a famous face rather than because it paid.

Frequently asked questions

How many micro influencers equal one macro influencer? On raw impressions, roughly ten to twenty micro creators match one macro, depending on median views. On credibility and on the feeling that a brand is having a moment, they do not substitute at all — those are different products bought from the same channel.

Do micro influencers really have higher engagement rates? Generally yes, and it is partly an artefact: smaller audiences are more homogeneous and more recently acquired, so a higher share of them see and react to each post. Treat it as a signal of audience health rather than a promise of conversion — engagement rate and purchase intent are only loosely related.

Should nano influencers be paid, or is gifting enough? Under about 10k followers, product plus a small fee is normal and gifting alone can work if the product is genuinely wanted. Expect a lower and less predictable posting rate than a paid deal; our gifting programme guide covers how to keep that conversion up.

Which tier is best for whitelisting and paid amplification? Micro and mid, almost always. You are buying the creative and the ad account permission, not the audience, so the cheaper creator with the better-performing video is the right buy — and mid-tier creators are usually more willing to grant paid-media rights than macro talent whose agents price them separately.
