Many brands use clusters of micro-influencers to drive meaningful conversations and scalable campaigns at a fraction of the celebrity budget.
As you know micro-influencers ranging from 10,000 to 100,000, they are often experts in specific fields or niches and have built a loyal community around their passions. Micro-influencers are known for their ability to drive engagement and conversions due to their close relationship with their followers.
