Many businesses are jumping on influencer marketing to reach potential customers and boost sales. But to determine if it is a worthy investment, you need to know how to measure the effectiveness of your influencer campaigns.
How you measure your return on investment (ROI) will depend on your campaign objectives. With that said, I will start by discussing the types of influencer marketing ROI before exploring how to track influencer marketing ROI in practice.

Types of Influencer Marketing ROI
Some of the major influencer marketing goals include driving sales, building brand awareness, and improving customer engagement. These goals define the various types of influencer marketing ROI.
1. Direct Sales ROI
Direct sales ROI focuses on the immediate sales from your influencer collaborations through promo codes, unique links, or exclusive offers.
To measure campaign ROI for direct sales, you need to track the number of sales driven by each influencer post. Other specific metrics to track include:
Returns on ad spend (ROAS): Revenue generated for each dollar spent on an influencer campaign. This is one of the clearest indicators of an influencer’s direct contribution to driving sales.
Conversion rate: The percentage of people taking the desired action after clicking on an influencer link or unique promo code. A strong conversion rate tells you the influencer’s content and audience are well matched to your offer.
Unique promo codes and UTM links are the most reliable influencer tracking methods for direct sales attribution. Assigning each influencer their own UTM parameters or a unique promo code tagged with the influencer’s handle means you can measure total sales generated per creator without guesswork.
2. Indirect Sales ROI
Brand awareness and customer engagement fall under indirect sales ROI because their contributions to total revenue are long-term.
For example, people might not convert immediately when they first encounter your brand through influencer campaigns. However, with proper nurturing through the customer journey, they become paying customers and positively impact your bottom line over time.
This is where customer lifetime value becomes the more relevant metric: a customer acquired through an influencer campaign may drive repeat purchases and stronger customer loyalty over years, well beyond what any last-click attribution model captures.
These types of returns are harder to track since it is challenging to assign a direct monetary value to metrics like brand awareness and engagement. However, lost attribution is a real cost of not measuring them. Each type of indirect ROI has its defining metrics, which I cover below.
Brand Awareness ROI
This type of influencer marketing ROI measures how well your influencer campaigns introduce new audiences, especially your target audience, to your brand.
To track influencer marketing ROI for brand awareness, you need key metrics like:
Reach: The total number of unique people who see the influencer content across all channels.
Post impressions: How many times the influencer’s content is shown, including to people who see it more than once. This contributes to earned media value and brand recall.
Follower growth: An increase in your social media following during and after influencer campaigns shows the influencer is helping expand your brand’s reach beyond your existing audience.
Website traffic: Use Google Analytics and UTM parameters on influencer links to track traffic driven by each influencer campaign. Assign each influencer their own UTM link or landing page so you can separate influencer-driven traffic from other channels.
Branded search volume: The number of people searching for your brand name. An uplift here after influencer campaigns signals improved brand recall and brand affinity.
Brand sentiment: How people feel about your brand. Analytics platforms and social listening tools like Sprout Social help track brand sentiment across other channels and flag shifts that correlate with specific influencer campaigns.
Brand recognition: People’s ability to recognize your brand assets, like your logo or visual identity. This is harder to measure but relevant for influencer campaigns running over a longer period.
Social media mentions: The number of people tagging or mentioning your brand, separate from branded search volume. High social mentions are a signal of genuine influencer exposure beyond the influencer’s own audience.
Earned media value (EMV): The estimated media value of the organic content your influencer campaigns generate, calculated based on what equivalent paid advertising placement would cost. EMV helps turn creators’ organic output into a number comparable to other paid channels.
Brand Engagement ROI
Successful influencer campaigns increase engagement. Awareness is the starting point, but interaction is what moves people through the customer journey toward purchase, repeat purchases, and customer loyalty.
Key engagement metrics to evaluate include:
Engagement rate: Likes, comments, shares, saves, and retweets as a percentage of reach or impressions. Engagement rate is one of the most useful indicators of content quality and audience alignment for a given influencer campaign.
Email sign ups: New email subscribers driven by an influencer’s campaign, typically through a dedicated landing page or promo code offer. Email sign ups from influencer campaigns are particularly valuable because they move people into a channel you own.
Average order value: If influencer campaigns are driving sales, track the average order value of influencer-referred customers against your baseline. A higher average order value suggests the influencer is attracting high-intent buyers.
Customer lifetime value: For service businesses and subscription brands especially, track not just the first purchase but the long-term customer lifetime of influencer-referred customers. Customer retention and repeat purchases are often higher for customers acquired through trusted influencer recommendations than through other paid channels.
How to Measure Your Influencer Marketing ROI
Let’s discuss the steps to measure influencer marketing ROI.
Determine Your Campaign Goals
Which influencer marketing goal is most relevant to your business right now? If your brand needs sales to meet a target, direct sales ROI is the priority. If you are a new brand, brand awareness influencer campaigns may deliver more long-term value.
Having clear campaign objectives makes it easier to quantify the performance of your influencer strategy and avoid chasing vanity metrics that look good in a report but do not inform data driven decisions.
Identify Relevant Influencer Marketing KPIs
Based on your campaign objectives, decide which key performance indicators are relevant. If your influencer campaign goal is brand awareness, focus on reach, impressions, and earned media value. If the goal is driving sales, focus on conversion rate, total sales generated, and average order value.
Once you have identified the specific metrics relevant to your campaign objectives, ensure you have the right analytics platforms and tracking tools in place. UTM parameters on influencer links, unique promo codes tagged with the influencer’s handle, and dedicated landing pages per campaign are the standard influencer tracking setup for making informed decisions from the data.
Add Up Your Expenses
The next step is to calculate how much you’re spending on your influencer marketing strategy. This includes agency or influencer fees, analytics software fees (see, e.g., Looker pricing), content production costs, and the cost for paid ads if you promote the influencer’s content.
Budget allocation across these line items varies significantly. Some brands run paid ads against influencer content as a retargeting ad layer, turning creators into a source of high-performing creative for other paid channels. Include all of it in your cost calculation or your campaign ROI will be overstated.
Calculate Your Campaign Revenue
For direct sales, track total revenue through each influencer’s unique links, unique promo codes, or UTM parameters to isolate the influencer’s contribution from other channels.
For indirect goals like brand awareness or email sign ups, assign a monetary value to each unit of relevant metric based on your historical data model. For example, if you know from past campaigns that a certain number of impressions generates a predictable number of future purchases, you can calculate an average value per impression.
This only works with an accurate, well-defined data model. Without it, these estimates are guesswork. If you do not yet have that data, the direct sales approach and unique promo codes give you a cleaner starting point for influencer tracking.
Calculate Influencer Marketing ROI
Once you have your total campaign costs and revenue, the calculation is straightforward.
ROI = (Revenue / Cost) × 100
If your total revenue was $40,000 and you spent $20,000:
($40,000 / $20,000) × 100 = 200% ROI

What Is a Good ROI for Influencer Marketing Campaigns?
A positive ROI means earning more than you spend. A negative ROI is the opposite.
On average, brands make $5.78 for each dollar spent on influencer campaigns, equivalent to a 578% ROI. Some of the top-performing influencer campaigns reach 2,000% ROI or more.

Tips for Better Influencer Marketing Results
A 578% ROI is good. But you can reach the top 13% of businesses making 20 times their initial investment by following these approaches.
Set Clear Campaign Objectives Before You Start
Before selecting any influencer, decide what your influencer campaign needs to achieve. Campaign objectives guide your budget allocation, your choice of influencer, the specific metrics you track, and the content quality standards you set. Skipping this step leads to influencer campaigns that generate impressions but not measurable results.
Turn Creators Into a Multi-Channel Asset
Do not limit influencer content to the influencer’s own social media profile. Share influencer posts across your own platforms, including your website, email list, and paid advertising. Repurposing influencer content this way maximizes the value of influencer fees by extending the reach of each piece of content beyond the influencer’s existing audience.
For brands running paid advertising, using influencer content as creative in retargeting ads and other paid channels consistently outperforms standard brand creative on engagement rate and conversion rate. This approach lets you turn creators into a performance asset across your full marketing stack.
Run Paid Ads on Your Influencer Content
Organic influencer exposure has limits. Amplifying influencer campaigns with paid advertising, especially as retargeting ads to people who have already visited your website or landing page, extends influencer reach to a qualified audience beyond the influencer’s followers and gives you direct control over the customer journey from influencer exposure to conversion.
Analyze Performance Regularly and Use It to Inform Future Campaigns
Regularly analyze performance across your influencer campaigns. Review the specific metrics tied to your campaign objectives and use what you find to make data driven decisions about future campaigns: which influencer content drove the strongest conversion rate, which unique promo codes generated the most total sales, which influencer strategy produced the highest campaign ROI, and which influencer post drove the most email sign ups or average order value uplift.
This approach builds a compound advantage over time. Each round of influencer campaigns generates data that makes the next round more effective.
Select the Right Influencer
Choosing the right influencer is the single biggest determinant of influencer marketing success. Look for influencers whose values, content quality, and audiences align with your brand and your target audience. The right influencer will produce authentic content that resonates with their followers rather than content that reads as a paid promotion, which directly affects conversion rate, brand sentiment, and long-term customer loyalty.
