Macro vs Micro Influencers:
Which Should Your Brand Choose?
Macro influencers have 100,000 to 1 million followers; micro influencers have fewer, usually between 10,000 and 100,000. Macro creators buy reach in a single post, while micro creators bring niche audiences, closer relationships and, on Instagram, higher engagement rates. The right choice depends on your objective and on the platform: on TikTok, the largest creators post the highest engagement rates. This guide compares both with benchmark data and campaign results from TANKE, an influencer marketing agency based in Paris.

- Macro influencers (100,000 to 1 million followers) deliver reach; micro influencers (about 10,000 to 100,000) deliver niche relevance and, on Instagram, higher engagement.
- Engagement depends on the platform: in Captiv8's 2024 benchmark, Instagram nano creators averaged 6.23% against 2.80% for accounts above 1.5 million followers, while on TikTok the largest creators led with 4.95%.
- Choose by objective and audience fit, and usually combine tiers: on the IKKS collaboration, micro-influencers drove three times the conversion rate of Tier 1 celebrities.
What is the difference between macro and micro influencers?
The difference starts with audience size, and everything else follows from it: reach, cost, closeness to the audience and the way content is produced. A systematic review of micro-influencer research published in Behavioral Sciences in 2024 uses these tiers: mega influencers above 1 million followers, macro influencers between 100,000 and 1 million, and micro influencers between 1,000 and 100,000. Many agencies, TANKE included, also separate nano influencers, under 10,000 followers, because they behave differently again.
| Tier | Followers | Strengths | Limits |
|---|---|---|---|
| Nano | Under 10,000 | Very close community, high trust, low fees | Small reach, many creators to manage |
| Micro | 10,000 to 100,000 | Niche expertise, strong engagement, good value | Reach requires several creators |
| Macro | 100,000 to 1 million | Large reach in one post, professional content | Higher fees, broader and less targeted audience |
| Mega | Over 1 million | Mass awareness, cultural impact | Highest fees, less control, lower engagement on Instagram |
The same review finds that micro-influencers perform better on audience trust and interaction than higher tiers, while micro and macro influencers are perceived as equally influential opinion leaders. In other words, a smaller audience does not mean less authority in its niche.
Average engagement rate: micro vs macro influencers
Engagement rate is the share of people who interact with a post. Benchmarks vary with the formula, so always check how a figure is calculated. Captiv8's 2024 Industry Benchmark Report for Creator Content analysed more than 5,000 organic posts from creator campaigns published between January 2022 and December 2023. It divides engagements by impressions on Instagram and by video views on TikTok:
| Tier (Captiv8) | Followers | TikTok | |
|---|---|---|---|
| Nano | Under 10,000 | 6.23% | 0.70% |
| Micro | 10,000 to 49,999 | 3.90% | 0.85% |
| Tier 3 | 50,000 to 299,999 | 4.91% | 1.66% |
| Tier 2 | 300,000 to 699,999 | 3.98% | 1.16% |
| Tier 1 | 700,000 to 1,499,999 | 3.08% | 1.34% |
| All Star | 1,500,000 and more | 2.80% | 4.95% |
Two lessons stand out. On Instagram, smaller creators engage best: nano influencers average 6.23%, more than twice the 2.80% of accounts above 1.5 million followers. The curve is not perfectly regular, since creators with 50,000 to 300,000 followers (4.91%) beat the micro tier (3.90%) in this sample. On TikTok, the pattern reverses: the largest creators lead with 4.95%, while nano and micro creators stay below 1%. TikTok distributes videos well beyond followers, and large creators who post on a steady rhythm keep a high organic reach.
Engagement rate is not the whole story either. A 2% engagement rate on a post seen by 500,000 people produces 10,000 interactions, twice as many as a 10% rate on a post seen by 50,000. Compare cost per engagement and cost per result, not the rate alone.
Micro influencer conversion rate: what campaigns show
Conversion is where micro influencers usually earn their place. Their audiences are smaller but more focused, and a recommendation feels closer to advice from a peer. TANKE's campaign data points the same way:
- IKKS: micro-influencers with 50,000 to 100,000 followers drove three times the conversion rate of Tier 1 celebrities on the fashion collaboration.
- Airalo: "niche travelers", such as budget travelers and digital nomads, converted 25% better than general lifestyle influencers on the eSIM campaign.
- Jardin Bio Étic: influencer affinity in "slow living" niches led to a 15% higher conversion rate on promo codes.
These are campaign results, not universal rates: conversion depends on the product, the offer and the tracking. Measure it per creator with unique links and promo codes. In Influencer Marketing Hub's Benchmark Report 2026, promo and discount codes are the most used tracking tool (45.9% of brands), ahead of affiliate links (26.0%).
When to choose macro influencers
- Launches and awareness pushes that need large reach in a short window.
- Mass-market products whose audience is broad rather than niche.
- Cultural moments and events, where one strong voice can set the tone of the conversation.
- TikTok campaigns, where the largest creators showed the highest engagement in Captiv8's benchmark.
- High-production content that the brand also wants to reuse in advertising.
Check the audience data before signing: a large account is only useful if its followers match your target in country, age and interests.
When to choose micro influencers
- Niche or expert products, where credibility in a community matters more than raw reach.
- Conversion objectives tracked with codes and links.
- Limited budgets that are better spread across several voices than spent on one post.
- Testing messages, formats and angles before scaling the best ones.
- Long-term ambassador programmes and local campaigns.
Brands are moving in this direction. In Influencer Marketing Hub's 2026 Benchmark Report, 52.83% of brands plan to increase or start work with micro influencers and 51.43% with nano influencers, against 20.59% for macro influencers.
How to combine macro and micro influencers
Most campaigns get the best results from a mix rather than a single tier. A common structure uses a few macro creators to create reach at launch, a wider group of micro creators for depth and conversion, and nano creators for community and local relays.
- Start from the objective: weight the budget towards macro for awareness and towards micro for conversion.
- Check audience overlap so several creators do not reach the same followers.
- Track every creator separately, with their own link or code.
- Move budget during the campaign towards the creators and formats that perform.

Frequently Asked Questions
What is the difference between macro and micro influencers?
Macro influencers have 100,000 to 1 million followers, micro influencers usually 10,000 to 100,000. Macro creators deliver large reach in one post and professional content, at higher fees. Micro creators have smaller, more focused audiences that trust them, and on Instagram they post higher engagement rates. Most brands combine both: macro for awareness, micro for engagement and conversion.
What is the average engagement rate for micro influencers?
It depends on the platform and the formula. In Captiv8's 2024 benchmark, based on more than 5,000 organic creator posts, micro influencers with 10,000 to 49,999 followers averaged 3.90% on Instagram, measured on impressions, and 0.85% on TikTok, measured on video views. Nano influencers under 10,000 followers reached 6.23% on Instagram, the highest of any tier.
Do micro influencers have a higher conversion rate than macro influencers?
Often, but not always: conversion depends on the product, the offer and audience fit. On the IKKS fashion collaboration managed by TANKE, micro-influencers with 50,000 to 100,000 followers drove three times the conversion rate of Tier 1 celebrities. Track each creator with a unique link or promo code to compare tiers on your own campaign.
How many followers does a macro influencer have?
A macro influencer usually has between 100,000 and 1 million followers. Above 1 million, creators are called mega influencers or celebrities. Below 100,000 they are micro influencers, and below 10,000 nano influencers. These ranges are conventions, not fixed rules, so check how each agency or platform defines its tiers before comparing benchmark figures.
Are micro influencers cheaper than macro influencers?
Per post, yes: fees rise with audience size, production level and exclusivity. What matters more is cost per result. A macro post can be cheaper per person reached, while micro creators are often cheaper per engagement or per sale. Compare cost per engagement and cost per acquisition across tiers rather than the price of a single post.
Should you use macro or micro influencers on TikTok?
TikTok behaves differently from Instagram. In Captiv8's 2024 benchmark, TikTok creators with more than 1.5 million followers averaged a 4.95% engagement rate on video views, while nano and micro creators stayed below 1%. Large creators are a strong option for reach on TikTok, with micro creators added for niche relevance and conversion.
Can you combine macro and micro influencers in one campaign?
Yes, and most campaigns perform best that way. Use a few macro creators to create reach at launch, a wider group of micro creators for depth and conversion, and nano creators for community relays. Check audience overlap, track every creator with its own link or code, and move budget towards the best performers during the campaign.
