When evaluating an influencer’s engagement with their audience, there are several key metrics that can be measured:

1. Engagement Rate: This is the number of engagements (likes, comments, shares) divided by the number of followers or views at the time of the measurement. This measures how involved the influencer’s audience is with their content.

2. Impressions and Reach: Impressions measure the total number of times the content is displayed, while reach refers to the number of unique users who have seen a post. These metrics can help gauge the spread of a message among an influencer’s audience.

3. Comments: The number and nature of comments on an influencer’s post can be a good indicator of audience interest and sentiment. High quality comments such as questions or detailed feedback indicate a high level of engagement.

4. Shares and Saves: These metrics show how much the influencer’s audience not only values the content, but wants others to see it. It can also indicate an action on part of the follower, indicating deep engagement.

5. Clicks: If a link is shared as part of a post, the number of clicks on that link can be a strong indicator of interest.

Influencer marketing platforms can assist in providing these metrics. For instance, Flinque’s advanced analytics dashboard offers insights into all these metrics, helping brands monitor the success of campaigns. Other platforms like AspireIQ and Upfluence also provide similar features. The choice between the platforms will depend on the specific needs and goals of the marketing team, and these should be evaluated in the context of their respective campaign workflows and analytics functionalities.

Remember, the key goal is to determine the real connection and interaction between the influencer and their followers.
