How Does TikTok Influencer Marketing Work?

TikTok influencer marketing involves collaborating with popular and influential TikTok creators to promote branded products or services to their audiences. Brands start by identifying relevant TikTok influencers whose audience aligns with their target market. Once they have negotiated a partnership, collaborating influencers create and share engaging content featuring the brand. This can include product reviews, tutorials, challenges, or other forms of branded content. The goal is to leverage the influencer’s audience, creativity, and authenticity to drive brand reach and awareness, increase engagement, and, ultimately, generate conversions and positive brand sentiment.

How To Measure the ROI of Your TikTok Influencer Marketing Campaigns: Key Metrics

Metrics play a vital role in measuring the return on investment (ROI) of your TikTok influencer marketing campaigns. They provide valuable insights into a campaign's performance, allowing you to assess the impact and value generated from your campaigns. You can also use these insights to optimize your campaign strategies, maximize your influencer partnerships, and drive better returns.

Here are a few key metrics that you should be tracking on a regular basis.

Engagement Rate

When it comes to TikTok influencer marketing, your engagement rate measures the level of audience interaction with influencer-generated content. This metric is typically calculated as a percentage based on likes, comments, shares, and other forms of engagement relative to the influencer's overall follower count or reach. 

To calculate your engagement rate, simply divide a campaign’s total engagement count (likes, comments, shares) by the total reach (number of followers). Then simply multiply your result by 100 to get a percentage. 

For example, if a TikTok video has 10,000 likes, 500 comments, and 200 shares, and the influencer has 100,000 followers, the engagement rate would be:

Engagement Rate = (10,000 + 500 + 200) / 100,000 * 100 = 10.7%

Top tip: Establish engagement benchmarks by researching industry standards and analyzing your past campaigns. Comparing your campaign's engagement rate to these benchmarks helps you understand its performance relative to similar campaigns and industry averages.

Follower Growth

Follower growth in TikTok influencer marketing refers to the increase in the number of social media followers or subscribers resulting from an influencer's content and promotional efforts. This is a valuable metric for measuring the return on investment (ROI) of your TikTok influencer marketing campaigns.

The formula to calculate follower growth rate is:

Follower Growth Rate = (New Followers - Lost Followers) / Initial Followers * 100

For example, if a TikTok account had 50,000 followers at the beginning of the month, gained 5,000 new followers, and lost 500 followers during that month, the follower growth rate would be:

Follower Growth Rate = (5,000 - 500) / 50,000 * 100 = 9%

Top tip: The key to consistent TikTok follower growth is regularly producing engaging and high-quality content. TikTok users are drawn to entertaining and captivating videos, so brands should collaborate with influencers who create original content that resonates with their target audience.


Conversions refer to the desired actions taken by the audience, such as making a purchase, signing up for a service, or completing a specific goal, as a result of an influencer's branded campaign.

To calculate your conversion rate for a specific TikTok influencer marketing campaign, simply divide the number of conversions generated by the campaign (such as purchases, sign-ups, or downloads) by the total number of clicks or engagements on the campaign's call-to-action (CTA) link or promo code. Then simply multiply your result by 100 to calculate your conversion rate percentage.

For example, let's say a TikTok influencer campaign generated 500 clicks. Out of those clicks, 50 users made a purchase using a discount code shared through the campaign. To calculate the conversion rate, simply divide the number of conversions (50) by the total number of clicks (500) and multiply the result by 100. In this example, the conversion rate would be 10%. This means that 10% of users who clicked on the CTA link converted into customers by making a purchase

Top tip: Make sure your influencer provides clear and compelling call-to-action instructions in their content, such as exclusive discounts, limited-time offers, or unique incentives.

Tips For Analyzing Your TikTok Influencer Marketing Campaigns

Let’s finish by looking at a few top tips for analyzing your TikTok influencer marketing campaigns:

  • Identify specific metrics that align with your campaign objectives, such as reach, engagement rate, conversions, or earned media value. This will help you establish a framework for measuring ROI effectively. You can then monitor the performance of your campaigns by tracking these metrics over time.
  • Look beyond vanity metrics and analyze the quality of engagements, such as meaningful comments, shares, or user-generated content. These engagements indicate genuine interest and brand affinity.
  • When you analyze the performance of influencer-generated content, also consider factors such as creativity, storytelling, and brand relevance.
  • Use the insights gained from your campaign analysis to refine your influencer marketing strategies. Continuously optimize your approach to maximize results and align with changing market dynamics.
  • Monitor and assess the sentiment around your brand or product after an influencer campaign. Social listening tools can help you measure a campaign’s impact on brand reputation and customer perception.
  • Use measurement and analytics tools such as those included in Influencity’s platform to gather data and insights on campaign performance.
