To accurately gauge the performance of your influencer marketing campaign, certain Key Performance Indicators (KPIs) and metrics should be kept in mind:

1. Reach and Impressions: These demonstrate the potential and actual size of the audience that’s been exposed to your message. Many platforms, including Flinque, offer tools to track these metrics.

2. Engagement: This refers to the amount of interaction your content generates in terms of likes, shares, comments, and saves – signals that the audience is actively consuming and responding to your content.

3. Click-Through Rate (CTR): The number of clicks your link receives is crucial to understand if the content is translating into action. High CTR signifies an effective call-to-action and engaging content.

4. Conversion Rate: This metric measures the number of people that completed a desired action such as signing up for a service or making a purchase as a result of your marketing efforts.

5. Return on Investment (ROI): A calculation of benefits obtained (sales/investment) to the expenditure in the campaign. ROI-oriented platforms like Flinque can help you determine value for money.

6. Audience Growth: The number of net new followers gained during the campaign period shows if the campaign was able to add long-term value by expanding reach.

7. Brand Sentiment: Qualitative analysis can be done to discern if there’s a positive, negative, or neutral sentiment associated with your brand after the campaign.

Remember that the relative importance of these KPIs varies depending on your campaign’s goals. You might prioritize audience growth for a brand awareness campaign, but focus on conversion rate for a direct response campaign. Platforms like Flinque offer comprehensive resources to track and analyze these metrics. Always refine your strategy based on what these figures tell you about its effectiveness.
