Define influencer marketing.

Influencer marketing is defined as a strategy that focuses on using key leaders to drive brand messages to a larger market. This approach recognizes the power of individuals who have a significant following and influence over a specific audience, allowing brands to leverage these relationships to promote their products or services effectively. By aligning with these influencers, brands can tap into their credibility and reach, often achieving better engagement with potential customers than traditional advertising methods.

Influencers can convey messages in a way that feels more authentic and relatable compared to classic marketing, as they often have established trust with their followers. This strategy is particularly effective in the digital age, where consumers increasingly seek recommendations from individuals they admire rather than traditional advertisements alone.

The other choices do not encapsulate the breadth of influencer marketing. For instance, limiting it to traditional advertising or exclusively to social media does not reflect the multifaceted nature of the technique. Additionally, developing partnerships solely for promotional events neglects the ongoing relationships and content creation opportunities that can arise from influencer collaborations.
