Why High Engagement Rates Don't Always Translate Into Results

High engagement rates don't always translate into results because there is a mismatch between an influencer's follower base and a brand's target audience. Engagement rate shows the intensity of followers' reactions, but whether that intensity is directed toward the brand's prospective customers needs to be confirmed separately.

What Does Engagement Rate Actually Measure?

Engagement rate is a metric that represents how strongly followers react to a post. A high number means the influencer's content is reaching followers and generating interest. However, this metric alone cannot tell you whether that reaction is directed at the brand's product or service.

Where Does the Mismatch Between Followers and Target Audience Occur?

When followers react strongly because they resonate with the influencer's personality or everyday content, that enthusiasm can be separate from interest in the actual value of the product the brand wants to convey. The same applies when the followers' age group or areas of interest don't overlap with the brand's prospective customers. In such cases, even if reactions to a post are high, they are less likely to lead to subsequent purchasing behavior or branded searches.

What Should Be Checked to Ensure Results?

It's necessary to look not only at engagement rate but also at metrics that indicate a deepening interest in the brand, such as save counts, profile visits, and trends in branded search volume. We believe that the volume of reactions and the depth of interest in the brand should be viewed along separate axes. As a basic principle of review, results should not be judged based on a single high number.

Is There a Way to Assess This Before Casting?

At the stage of considering casting an influencer, you can check how much overlap there is between the influencer's followers' age group and areas of interest and the brand's assumed prospective customers. Looking at the content of comments on past posts can provide clues about what followers are interested in and reacting to.
