Influencer marketing uses social media users with an engaged and loyal audience to drive authentic conversation and engagement around a brand’s products and message.

Influencers help brands drive conversation and engagement around a particular topic, discussion, or niche area.



As millennial consumers move away from traditional media and become more invested in social media and the influencers therein, influencer marketing has seen a huge boost in popularity.

“Influencer marketing is growing because it’s a great way to get your products in front of an audience with an authentic voice. Many brands are seeing top-of-the-funnel value by getting more eyeballs on their brand’s offering. There’s power in putting the right products in front of the right audience  — with an authentic voice.”

Social Media Influencer Marketing Statistics 2018

Here are 11 social media influencer marketing statistics to keep in mind as you craft your 2019 marketing strategy.

1. Influencer marketing on Instagram continues to grow, with over 1.5 million posts in 2017.

According to data from Klear, over 1.5 million Instagram posts were tagged with the FTC-mandated #ad or #sponsored hashtags in 2017.
As Instagram use grew in 2018 — the platform hit 1 billion active users in June 2018, up from 800 million in September 2017 — it’s safe to assume that the reach (and sheer volume) of influencer marketing grew along with it.


2. Sponsored Instagram posts generated about 1 billion total likes in 2017 alone.



Those #ad and #sponsored posts tend to generate a lot of engagement — an average of 682 likes per post, to be exact.

While these numbers might seem low compared to the hundreds of thousands of likes that traditional celebrities rake in, keep in mind that the most effective influencer marketing isn’t about reaching as many people as possible, but rather about reaching the right audience.


3. Instagram is the most widely-used and effective influencer marketing platform for reaching millennials.

More proof that millennials are over traditional marketing techniques. To reach these consumers, brands to embrace more approachable, authentic forms of marketing.


6. Micro influencers have higher engagement than celebrities.


Micro influencers — defined by Digiday as those with between 10k and 100k followers — see higher like and comment rates than accounts with higher follower numbers. This means that micro influencers tend to have the best combination of follower count and engagement.

This is especially valuable when you consider how highly brands value engagement.


7. According to a report from Linqia, brands rank engagement as the most important goal of influencer campaigns.

One of the biggest draws of influencer marketing is the authenticity of the content. When content seems authentic and relatable, audiences are more likely to engage.

It’s hard for brands to generate this under their own name; meanwhile, influencers are already creating regular authentic content with millions of engagements.

8. 87% of influencer campaigns have a budget of $100k or less.





$100k isn’t pocket change, but compared to the ad spend for traditional media such as TV or print, influencer marketing can be extremely affordable, especially if you consider how high the returns can be:


9. Some studies show influencer marketing returning as much as $6.50 for every $1 spent.
