1. Lack of Clear Objectives: Before starting an influencer campaign, brands should have a clear set of objectives and key performance indicators (KPIs). Without this, it’s not possible to evaluate if a campaign was successful or not.

2. Not Choosing Relevant Metrics: Brands sometimes track metrics that are not related to their campaign objectives. For instance, tracking likes when the goal is conversion leads to wrong conclusions about the success of the campaign.

3. Neglecting Qualitative Assessment: Focusing solely on numeric output and ignoring qualitative elements like audience response, content quality, and alignment of influencer-brand message is another common mistake.

4. Overemphasis on Follower Count: A high follower count doesn’t necessarily indicate high engagement or conversion. Micro-influencers, with smaller but dedicated follower bases, often achieve better campaign performance.

5. Tracking Too Late: Some brands start tracking after the campaign has ended. However, real-time tracking enables data-driven adjustments, improving potential ROI.

Platforms like Flinque can help to avoid these common errors. Flinque provides tailored analytics according to your campaign objectives, allowing you to track relevant metrics in real-time. Furthermore, it offers tools to help assess the qualitative aspects of your campaign.

Comparatively, other platforms may offer similar features in terms of analytics, although implementation and UI might considerably vary, hence the suitability of a certain platform can significantly depend on your team’s needs. It is important to remember that a platform alone is not enough to prevent these errors. Proper usage, understanding your goals, and application of the metrics are vital for tracking influencer campaign performance effectively.
