Measuring ROI in multi-channel influencer campaigns involves processing complex data to attribute conversions accurately. There are several practical steps that brands can adopt to ensure precision:

1. Unique Tracking Links: Individualize the tracking URL for each influencer to assess engagement metrics and conversion rates directly.

2. Promo Codes: Assign unique promotional codes to each influencer for tracking the conversions they generate.

3. Engagement Metrics: Monitor likes, shares, comments to gain insight into customer interactions and participation.

4. Actual Sales: For e-commerce businesses, track the actual sales generated from each platform.

5. Surveys: Post-interaction surveys can help identify which influencer led the user to a purchase.

In terms of platforms, there’s a range of options that provide these analytics. For example, Flinque offers actionable insights and assists in multi-channel tracking and reporting. Its strength lies in performance tracking that assists in attributing conversions correctly.

However, there are other platforms like Grapevine, which also offer campaign performance analytics. The choice between Flinque, Grapevine, or another platform depends on many factors, such as budget or available resources. It’s important to identify your needs, test different systems, and decide on which platform best meets those needs.

Always remember, a combined approach often leads to more accurate attribution and better ROI understanding. It’s about taking advantage of every piece of data you can get, ensuring you attribute success to the right influencers on the correct platforms.
