Case Study: Macro vs. Micro Influencers

Micro-influencers have smaller followings than macro-influencers (think 10,000 to 90,000 followers as opposed to hundreds of thousands). Micro influencers are often real people, not pop stars or reality television sensations. Micro Influencers will drive 3-5x more sales. Macro-influencers will drive significantly more impressions.

It’s a tale as old as time (well not as old as Beauty and the Beast but stay with us). The age old debate of who gives you a better ROI? Mega Influencers with millions of followers? Or micro influencers, who are cheaper and usually easier to deal with? Well, since we’ve launched, we have a definitive answer.

Let’s get into our findings.


We took a look at our data and measured engagement rates of mega influencers vs. micro influencers. Reason we did this: there’s high correlation between engagement rates and sales. We wanted to see if that held up with the influencers we found. We also looked at surveys and results of influencer campaigns ran by companies who engaged in micro and mega influencers

Engagement of Macro and Micro Influencers

When we looked at the data for mega influencers, we found an interesting trend. There was an exponential decrease in engagement the more followers an influencer had. When we looked at our data, those between 800 – 1,200 followers got likes on their posts about 9% of the time. Users with 2 million+ followers only received likes 3.5% of the time. There is a clear downward trend between follower sizes and post likes. But the question becomes, is that really a negative? Taking a look at our trend,

1200 followers * 9%  = 108 likes 


2 million followers * 3.5% = 70,000 likes

Hard to argue with math. Even though there’s a clear negative trend that occurs when influencers have a high follower count, it still generates a ton more likes and views than a micro influencer would. That being said, what about sales and ROI? Who really drives the most sales? Let’s take a look…

Sales Generated from Macro and Micro Influencers

For this part, we had to look at campaigns from brands who were open to publishing their results with the world. Stephany Robbins recently ran a campaign for a health food company and engaged in both macro and micro influencers. Here was her definition of a mega and a micro influencer (pretty in line with our own findings):

Macro Influencer

  • Over 600,000 followers on Instagram
  • Over 24,00 followers on Facebook
  • 300+engagement on all posts
  • Provides high quality images and content, professional influencer
  • Well respected by brands and niche community
  • Experienced in both sponsored and performance based campaigns

Micro Influencer

  • Around 10,000+ followers on Instagram
  • 8,000+ followers on Facebook
  • Provides high quality images and content
  • Well respected by brands and niche community
  • Experienced in both sponsored and performance based campaigns

The results?

Other campaigns (that we can’t share data around quite yet – we’ll update this post once we get the A-OK to publish the results from our customers) have run a similar course, with Micro-influencers driving 3-5x the sales of the mega-influencers. Although they’re not getting the same reach as macro or mega influencers, the higher engagement that they drive, coupled with the response rates they generate compared to mega influencers helps their followers feel more involved, and therefore more likely to buy from them.

Costs of hiring macro vs micro influencers

In our research, we found that mega influencers can cost way more than what your potential revenue could be. Take a look at the cost structure of mega influencers:

100k – 500k$12,500$5,000$5,000$2,000
500k – 1m$25,000$10,000$10,000$2,000
1m- 3m$125,000$50,000$50,000$20,000
3m – 7m$187,500$75,000$75,000$30,000
7m +$300,000$150,000$150,000$60,000

Now let’s compare that cost to micro influencers.

Fewer than 1000$80
10k – 50k$210
50k – 100k$280


So if you’re looking to drive sales and count dollar for dollar, then micro influencers will consistently give you a greater bang for your buck. They’ll drive more engagement, tend to have more invested followers who are more emotionally connected to the influencer’s niche topic, and will end up converting into customers at a higher rate. However, if you’re goal is to drive brand awareness, get that “cool factor” rub from associating with a cultural icon, then macro influencers are the way to go, just don’t be surprised if your total sales count is less than what your executive team might hope for.
