Influencer marketing has become a cornerstone strategy for brands aiming to leverage social media's expansive reach. To gauge the effectiveness of these campaigns, it's crucial to measure specific Key Performance Indicators (KPIs). This guide will delve into the most critical KPIs for influencer marketing, helping you track success and optimize your efforts. This guide will use the Favikon app as a tool to measure and track these KPIs. 

1. Reach and Impressions

Definition f Reach: The total number of unique users who have seen your content.

Importance: Reach indicates the potential audience size. A high reach means your message is visible to a broad audience, which is crucial for brand awareness. In this example, the ‘Avg Views’ column indicates the reach of the influencer. This entails that, on average, the posts of influencer Justin Welsh’s will be seen by approximately 59.7k users. 

Definition of Impressions: The total number of times your content is displayed, regardless of whether it is clicked or not.

Importance: Impressions help gauge the visibility of your content. While it may include repeated views by the same user, it’s a good indicator of content exposure.

2. Engagement Metrics

Definition of Likes and Shares: The number of likes and shares your content receives.

Importance: These metrics reflect audience approval and content virality. High likes and shares suggest that the content resonates with the audience.

Definition of Comments: The number of comments on your posts.

Importance: Comments indicate a deeper level of engagement. They can provide insights into audience sentiment and feedback about your brand or product. Likes, shares and comments are grouped as ‘engagement’. The Avg. engagement tab totals the likes, comments and shares to reveal the average trend for the influencer.

Definition of Click-Through Rate (CTR): The ratio of users who click on a link compared to the total users who view the content.

Importance: CTR measures the effectiveness of your call-to-action (CTA) and the ability to drive traffic to your website or landing page.

3. Conversion Metrics

Definition of Conversion Rate: The percentage of users who take a desired action after clicking through your content (e.g., making a purchase, signing up for a newsletter).

Importance: Conversion rate is a direct measure of your campaign's success in driving profitable customer actions.

Definition of Cost Per Conversion (CPC): The total cost of your campaign divided by the number of conversions.

Importance: CPC helps evaluate the financial efficiency of your campaign. Lower costs per conversion indicate a more effective use of your budget.

4. Sales and Revenue Metrics

Definition of Sales Lift: The increase in sales attributed to the influencer marketing campaign.

Importance: Sales lift quantifies the direct impact of your campaign on sales, highlighting its effectiveness in driving revenue.

Definition of Return on Investment (ROI): The revenue generated from your campaign minus the cost, divided by the cost of the campaign.

Importance: ROI provides a comprehensive view of your campaign's profitability. A high ROI indicates a successful campaign with significant financial returns.

5. Audience Growth Metrics

Definition of Follower Growth: The increase in the number of followers on your social media accounts during and after the campaign.

Importance: A growing follower base suggests that the campaign successfully attracts new audience members who are interested in your brand.

Definition of Subscriber Growth: The increase in the number of email or newsletter subscribers.

Importance: Subscriber growth indicates a successful campaign in expanding your potential customer base and improving future engagement opportunities.

6. Content Performance Metrics

Definition of Content Shares and Saves: The number of times your content is shared or saved by users.

Importance: Shares and saves suggest that users find your content valuable and worthy of being saved for later or shared with others, indicating high content quality.

Definition of User-Generated Content (UGC): Content created by users about your brand, often inspired by your campaign.

Importance: UGC signifies high engagement and organic promotion. It enhances brand credibility and can be leveraged in future marketing efforts.

7. Brand Sentiment

Definition of Sentiment Analysis: The process of analyzing the emotions and opinions expressed in user comments and interactions.

Importance: Understanding brand sentiment helps gauge public perception and identify areas for improvement. Positive sentiment reflects well on your campaign, while negative sentiment indicates issues that need addressing.

Definition of Brand Mentions: The number of times your brand is mentioned across social media and other platforms.

Importance: Frequent brand mentions increase visibility and awareness. Monitoring mentions helps track the spread and impact of your campaign.

8. Influencer-specific metrics

Assessing the credibility and authenticity of the influencer is crucial to the success of the campaign:

  • Authenticity and trust: The authenticity and credibility of the influencer are key factors for the success of the campaign. An authentic and credible influencer is more likely to engage their audience and generate positive results for your campaign. This accounts for suspicious following, managed or manipulated engagement or any other malpractices. Favikon offers authority and influence scores to help you cut down on these calculations and research, saving your time and effort in search of the right partner for your business.


Measuring the right KPIs in your influencer marketing campaigns is crucial for understanding performance and optimizing future efforts.
