Influencer marketing leverages content creators with engaged audiences to promote brands, products, or services. By collaborating with influencers—ranging from mega to micro—influencers, businesses can reach niche markets authentically. This strategy thrives on trust, as followers view influencers as relatable and credible. Platforms like Instagram, TikTok, and YouTube dominate the space, driving impactful campaigns through posts, stories, or reviews. For brands, influencer marketing offers cost-effective exposure, increased engagement, and the ability to build stronger customer connections in a competitive digital landscape.
