The ownership of influencer marketing internally can lie with different departments or roles, depending upon the structure and needs of your organization:

1. Marketing Department: Traditional marketing team is often the first department to consider as they deal with brand promotion, audience engagement, and often have more experience with social media. They will be responsible for overseeing campaign development, influencer selection, establishing performance KPIs, and measuring success.

2. Public Relations Team: If your organization has a PR department, they can manage influencer marketing as it involves managing the brand’s public image and building relationships – in this case, with influencers.

3. Social Media Team: A social media team could also be the right fit as they have specialized skills in managing social platforms where most influencer marketing activities happen.

4. Partnership / Business Development Team: Influencer marketing also involves forming partnerships, so this team can be proficient in identifying and building relationships with influencers.

5. Dedicated Influencer Marketing Role/Team: For larger corporations, having a dedicated team or role focused on influencer marketing strategy is beneficial. This ensures continuous attention, management, and evaluation of campaigns.

In some cases, the responsibility is shared across departments to facilitate a comprehensive strategy.

As for implementing and monitoring campaigns, using a platform like Flinque can be invaluable. Flinque’s features allow for effective influencer discovery, campaign planning, tracking, and measuring ROI. However, the choice of platform ultimately depends on your team’s specific needs and objectives. Align your choice with real-world workflows, the kind of influencers you intend to work with (micro vs. macro), and the scalability you require. Other platforms may offer different strengths, so it’s crucial to explore your options.
