6 Crucial Metrics You Must Track in Your Influencer Marketing Strategy

The effectiveness of influencer marketing stems from its ability to amplify word-of-mouth endorsement across digital platforms, growing into a massive $2.1 billion sector. 

Gone are the days when only a handful of high-profile influencers dominated the scene. Today, influencer ranks span from nano-influencers (with under 1,000 followers) to macro-influencers (with up to a million followers), broadening the scope for brands to connect with their audience through diverse voices. 

This marketing approach enables brands to promote virtually anything by strategically aligning with influencers, made even more accessible by artificial intelligence which simplifies the matching process. Moreover, this strategy isn’t confined to Instagram alone; TikTok, YouTube, and Facebook have also become key players.  

As a marketer, determining the effectiveness of your influencer partnership is crucial. 

Measuring campaign performance is essential, and this involves tracking specific key performance indicators (KPIs). This article will discuss six crucial KPIs to monitor in your influencer marketing campaigns:

1. Website Traffic
2. User Engagement
3. Conversion Rates
4. Brand Recognition and Perception
5. Growth of Audience
6. Investment Returns (ROI)

Setting Goals for Your Influencer Campaign

Prior to launching an influencer collaboration, it’s essential to clarify your objectives. Consider the unique advantages an influencer brings to your campaign compared to other marketing strategies. 

Reflect on past campaigns to identify areas of success and opportunities for improvement. 

Define your primary objectives, as they will guide the strategy, content, and platform selection for your influencer campaign. Are you aiming to increase brand visibility, generate leads, enhance conversions, or drive sales? 

Choosing the right social media platform is also vital. Determine where your brand currently engages with its audience most effectively and where your target demographic is most active.

According to Statista, the preferred platforms for influencer marketing in the United States will evolve from 2020 to 2025, with TikTok leading in engagement rates (10%-15%) followed by Instagram (1%-4%) as indicated in The Influencer Marketing Benchmark Report 2024.  

Consider platform popularity when planning your campaigns and selecting influencers.  

Top tip: Utilize tools like Heepsy, BuzzSumo, or TikTok Creative Center to discover influencers who align with your objectives. 

Monitoring Your Influencer Marketing Efforts

Understanding your campaign goals is only the beginning. The next step involves tracking and evaluating your influencer marketing initiatives. 

For accurate campaign tracking, incorporate tracking parameters or UTMs (Urchin Tracking Modules) within your URLs. For promotional campaigns, tracking performance via discount codes (e.g., SUMMER20) can be effective. 

Google Analytics (GA4) is a crucial tool for campaign reporting and monitoring. Other options include sales platforms or specialized tools such as Upfluence, Keyhole, or Grin. 

Let’s examine the KPIs that will help you gauge the success of your influencer marketing efforts. 

1. Website Traffic

Website traffic is a key metric for evaluating digital marketing initiatives, providing insight into the reach and overall impact of your content.

Understanding traffic dynamics can also shed light on campaign effectiveness. For instance, an uptick in traffic without a corresponding increase in conversions may indicate a disconnect on the landing page. Solutions could include tweaking the landing page design or experimenting with different calls-to-action.

Traffic-related metrics to monitor include:

• New visitors
• Total sessions
• Referral sources
• Page views
• Duration of site visits

2. User Engagement

User engagement offers a deeper understanding of how your audience interacts with your campaign content beyond mere visibility metrics like traffic and reach.

This KPI is essential for assessing how effectively your campaign resonates with your target demographic, which can influence customer loyalty and brand relevance. 

To benchmark your campaign’s engagement levels, consider the engagement rates of TikTok users in the United States by influencer category and industry. 

Engagement can be quantified through various actions, depending on the platform, such as:

• Likes
• Reactions
• Shares
• Comments
• Clicks
• Polls
• Pins
• Video views
• Mentions of the brand

To calculate engagement rate, divide the total interactions by the number of followers and multiply by 100.

3. Conversions

Conversion rate is a pivotal KPI, highlighting the campaign’s success in turning viewers into customers or leads.

Tracking conversions can involve comparing sales data before, during, and after the campaign or using more intricate methods such as affiliate links, UTM codes, promo codes, dedicated landing pages, and link tracking.

It’s crucial to go beyond lead generation metrics to understand the ratio of leads that convert into actual sales.

“ 56% of marketers leverage influencer campaigns to create user-generated content, while 23% aim for sales generation.”

4. Brand Recognition & Brand Perception

Influencers facilitate access to new audiences, helping enhance brand visibility and forge new connections.

For emerging brands or those in niche markets, collaboration with well-aligned influencers can significantly boost brand recognition and forge strong customer relationships based on shared values.

To evaluate brand awareness, measure campaign reach, new brand encounters, and reinforcement of your brand among existing prospects through tracking impressions and social media analytics. 

Brand sentiment can be assessed using social listening tools or direct customer feedback via surveys and polls. 

5. Audience Growth Rate

This metric focuses on the increase in your audience size as a result of the campaign, distinguishing itself from reach and awareness by emphasizing engagement and sustained interest.

To monitor audience growth, analyze follower data from social media analytics and compare the increase during the campaign period to baseline figures.

Audience growth rate is calculated by subtracting the initial follower count from the count post-campaign, dividing by the initial count, and then multiplying by 100 to derive the percentage increase.

6. Return on Investment (ROI)

ROI stands out as one of the most crucial KPIs, focusing on the profitability of your campaign. Achieving a positive ROI indicates that the campaign’s revenue surpassed its costs, including influencer fees and other expenses.

Although ROI directly relates to financial gains, Earned Media Value (EMV) is another significant measure of influencer campaign efficiency, reflecting the organic exposure value.

To estimate EMV, incorporate engagement metrics and impressions into your calculation according to formulas like those provided by Later.

Conclusion: Influencer Marketing KPIs

What was once perceived as a trend or a strategy exclusive to big brands has evolved, with the rise of nano and micro influencers enabling a wider range of businesses to harness influencer marketing effectively. The key is clear goal setting, selecting the appropriate platform, and partnering with influencers that resonate with your brand’s message and audience. 

By focusing on these six KPIs, gain comprehensive insights into your campaign’s performance, allowing for necessary adjustments to optimize results. 

Ultimately, the aim is to establish a fruitful collaboration with influencers who can genuinely connect with your target audience.
