Influencer engagement: what is it and how do I work it out?

In digital marketing, the engagement rate refers to the level of “commitment” between an online audience with a brand or a person. It’s extremely valuable and intangible insight for companies nowadays, which must opt for values and practices to make their audience fall in love with their brand and therefore become loyal customers.

When we talk about an influencer’s engagement rate, we’re referring to the sense of commitment they’ve managed to generate amongst their online audience.

An influencer’s engagement rate is a valuable metric that serves as a solid prediction as to whether or not your marketing campaign will be a success. Why? Because the results of a marketing action tend to be measured by looking at the responses received from social media users to messages published by influencers on their social media feeds, which are usually related to a brand or its campaign.

These responses can be any of the following:

  • Likes
  • Comments
  • Shares
  • Page visits

Now that we’ve briefly covered the importance of an influencer’s engagement rate, let’s take a look at what exactly it is and how we can calculate it.

What is influencer engagement: definition

Influencer engagement rate is one of the most important KPIs in Influencer Marketing. It’s an important parameter which allows brands to measure the level of interaction between an online audience and marketing content, by analysing likes, comments, retweets and shares, amongst other interactions.

Engagement rate is an indicator of an online audience’s commitment

In terms of a campaign’s development, engagement rate is one of the most commonly used criteria when selecting the best influencers for a collaboration. An influencer’s engagement rate is a great indication of whether or not their profile is interesting for a brand and its target audience.

How to calculate engagement rate

In order to calculate an influencer’s engagement rate, you need to take into account the average interaction rate for their publications.

Influencer engagement rates can be divided into two categories:

  • A profile’s engagement rate is the average engagement obtained for their publications.
  • A campaign engagement rate is the total number of interactions on all publications from a specific campaign (Social Reach).

Engagement rate for a profile
