An effective suite of analytics or indicators to quantify the success of influencer campaigns may include:

1. Reach and Impressions: These show the number of people who saw your campaign and the number of times your content was displayed, respectively.

2. Engagement Metrics: They encompass likes, comments, shares, mentions, and anything that requires some level of user interaction.

3. Conversion Rates: Did the campaign directly lead to a desired action? For instance, a purchase or registration could be a conversion.

4. Audience Growth: Evaluate whether you increased followership or subscribership due to the influencer’s campaign.

5. Click-through Rate (CTR): This measures how often people clicked on the link to your website or landing page from the campaign.

6. Return on Investment (ROI): This measures what you gained by investing in the campaign, taking into consideration your original goals and objectives.

For example, influencer marketing platforms like Hootsuite and BuzzSumo provide detailed analytics around these metrics, while others like Flinque also offer additional insights, including sentiment analysis and audience demographics.

It’s important to note that the best tool for tracking campaign success depends on the specific goals and needs of your team. It’s advantageous to review what different platforms offer and align their features with your unique campaign objectives.
