In order to generate creative content, user engagement is an essential KPI. Because how the target group accepts the content is shown above all in the interactions and the way the community deals with the content. The interactions include not only likes, comments and shares, but also the saving of Instagram postings and the link clicks to websites. The engagement basically includes all reactions to the influencer's content - so by far more than just likes. For example, shares make a particular contribution to increasing reach. It is the quality of the followers that counts in order to achieve a high engagement rate. If the community deals with the content, this also has a positive effect on the Instagram algorithm.
