A survey of 2 million social media influencers by influencer marketing platform Markerly showed that for unpaid posts, Instagram influencers with fewer than 1,000 followers have a like rate of about 8 percent, while those with 1,000 to 10,000 followers have a like rate of 4 percent.
As following base continues to increase, like rate keeps decreasing. Instagram influencers with 10,000 to 100,000 followers see a 2.4 percent like rate, compared to 1.7 percent for those with 1 million to 10 million followers and more. Comment rate follows a similar pattern.
The findings apply to sponsored Instagram posts, too, which suggests the sweet spot for maximum impact is an influencer with a following in the 10,000 to 100,000 range. Call them “micro-influencers.”
Here’s an infographic that tells you all you need to know about micro-influencers and best practices.
