Define influencer marketing.

Influencer marketing is defined as a strategy that utilizes key leaders or individuals who have a significant following and influence within a specific niche or market to promote a brand's message to a larger audience. These influencers can sway the opinions of their followers due to their credibility and relationship with them, making their endorsement valuable for brands seeking to enhance their market reach and resonate with potential customers.

This approach stands out because it leverages personal connections and authenticity. Instead of relying solely on traditional advertising methods—which may not have the same level of trust among consumers—brands that engage in influencer marketing can create more organic and relatable content. This method often results in higher engagement rates and allows brands to tap into the established trust that influencers have built with their audiences, thus amplifying their message effectively.

Other strategies mentioned, such as paid advertisements or tactics centered on SEO specialists, do not capture the essence of influencer marketing, which is fundamentally about leveraging the personal influence of specific individuals rather than relying on more conventional forms of advertising or technical marketing tactics like SEO.
