How to Measure ROI of Influencer Marketing Campaigns?
One of the biggest challenges in influencer marketing is measuring return on investment (ROI). Unlike traditional online advertising, the effects of influencer collaborations are often harder to measure. In this article, we'll show you how to do it effectively.
What is ROI in Influencer Marketing?
ROI (Return on Investment) is the ratio of profit to costs incurred. In influencer marketing, we measure how much you earned relative to campaign expenses.
Basic formula:
ROI = ((Campaign Revenue - Campaign Cost) / Campaign Cost) × 100%
Example
- Campaign cost: $2,500
- Generated revenue: $8,750
- ROI = ((8750 - 2500) / 2500) × 100% = 250%
Key Metrics to Track
1. Earned Media Value (EMV)
The value of organic reach generated by the campaign. Calculated based on CPM for the given platform.
Formula: EMV = (Reach / 1000) × Benchmark CPM
2. Cost per Engagement (CPE)
How much you paid for each interaction. Check our CPM vs CPE comparison for better understanding.
3. Conversion Rate
Percentage of people who completed a desired action (purchase, registration, download).
4. Customer Acquisition Cost (CAC)
Cost of acquiring one customer through the campaign.
Conversion Tracking Methods
Discount Codes
Each influencer gets a unique code. Easy to attribute sales to specific person.
Pros: Simple, accurate, motivating for influencer Cons: Reduces margin, customers may search for codes online
Tracking Links (UTM)
UTM parameters in links allow tracking traffic in Google Analytics.
Example:
influaudit.pro?utm_source=instagram&utm_medium=influencer&utm_campaign=john_smith
Dedicated Landing Pages
Each influencer directs to a separate landing page.
Conversion Pixels
Tracking user actions after clicking on ads.

ROI Measurement Mistakes
❌ Ignoring Brand Awareness
Not all campaigns aim for direct sales. Building brand awareness has value too.
❌ Too Short Attribution Window
A customer may buy a product a week after seeing the ad. Track for at least 30 days.
❌ Ignoring Hidden Costs
Team time, production, shipping - all of this counts as cost.
ROI Reporting Framework

- Campaign goals - what did you want to achieve?
- Reach metrics - impressions, reach, ER
- Conversion metrics - clicks, purchases, registrations
- Costs - complete expense breakdown
- ROI - calculated according to formula

Summary
Measuring ROI requires:
