There are many critical metrics used in tracking the success of influencer marketing campaigns:

1. Engagement Rate: This is the proportion of followers that interact with an influencer’s content. It helps you understand how active and engaged an influencer’s audience is. It can be calculated by the total number of likes, shares, and comments divided by the total number of followers.

2. Reach: This metric tells how many unique users saw the post or content.

3. Impressions: The number of times the content was viewed, irrespective of whether it was by the same user or different users.

4. Click-through Rate (CTR): This represents the ratio of users who clicked on a specific link to the total number of users who viewed the campaign.

5. Conversion Rate: The number of desired actions (like sales, sign-ups, etc.) taken divided by the total traffic generated.

6. Return on Investment (ROI): This measures the amount of return on a particular investment, relative to the investment’s cost.
