Influencer marketing is a branch of digital marketing, its campaigns are essentially endorsements by social media influencers of certain products or services and their introductions to various audiences. In this day and age, the demand for this kind of marketing exists in so many branches of the economy. It gives a level of trust that other kinds of marketing can not match.

In this article, we want to review a number of case studies to demonstrate what marketing objectives can be achieved with influencer marketing, and its potential for app marketers.

Influencer marketing is deeply personal, it’s about a human touch, a connection between an influencer and people who trust her or his opinion. Influencers need to be creative, artistic, and authentic for an influencer marketing campaign to succeed.
