Micro influencers make excellent brand ambassador because of their genuineness, in-depth knowledge of a particular niche, affordability, increased engagement rates, and potential for long-term collaborations. Their endorsements are sincere because their smaller, more active fan base gives them greater trust. They thoroughly understand their target market, specialize in particular niches, and frequently charge less. Their engagement rates are higher, and they are more likely to establish enduring relationships that will give the brand steady exposure.
