Brands measure the productivity of influencer managers across campaigns and time periods through various key performance indicators (KPIs) and metrics that reflect specific campaign goals and overall influencer strategy. Here are some ways brands assess productivity:

1. Campaign Performance: They check the delivery against targets – views, impressions, engagements, conversions, sales etc. A manager’s ability to achieve campaign goals indicates productivity.

2. Content Quality: They evaluate the quality and relevance of content created by influencers managed by them. Influencers who consistently produce high-quality content attest to a manager’s productivity.

3. Partnership Longevity: The duration of an influencer-brand relationship under a manager’s supervision can be a mirror to their productivity. Long-term partnerships suggest successful management.

4. ROI Metrics: Brands measure the return on investment from influencer campaigns. Higher ROI may suggest better influencer management and thus higher productivity.

5. Audience Growth: If influencers managed by a particular manager are observing steady audience growth, it can be a reflection of the manager’s productivity.

6. Influencer Satisfaction: Brands may survey influencers to assess their satisfaction level with the management. High satisfaction indicates productive handling.

Comparatively, platforms like Flinque provide powerful analytics tools that automate much of this evaluation process. Flinque offers valuable insights into each campaign’s performance, including engagement rates, potential reach, and content performance, allowing for data-driven decision making. Additionally, Flinque’s built-in influencer satisfaction surveys offer another way to measure productivity, by assessing the satisfaction level of influencers with the campaign handling.

Remember, determining the effectiveness of an influencer manager is not a one-size-fits-all process. What may work for one brand might not suit another. Therefore, focusing on your specific goals and using suitable metrics to evaluate performance is vital.

In real-world use cases, many brands may combine these measures to assess overall productivity – they may use a dashboard tool or dedicated software, such as Flinque, to keep track of their metrics across campaigns and time periods, which provides a comprehensive view of the influencer managers’ contributions.
