Brands should track several key metrics to measure the success of their influencer affiliate campaigns, including:
1. Click-through rate (CTR): The percentage of people who click on the affiliate link out of the total number of impressions.
2. Conversion rate: The percentage of people who make a purchase after clicking on the affiliate link.
3. Return on investment (ROI): The revenue generated from the campaign compared to the cost of running it, including commissions paid to influencers.
4. Earned media value (EMV): The estimated value of the exposure and engagement generated by the influencer's content.
5. Audience growth and engagement: The increase in followers, likes, comments, and shares on the brand's social media profiles as a result of the influencer's promotion.
