ROI Influencer Marketing: Measurable and Optimized Success

You’ve successfully found great influencers, developed an influencer marketing campaign with them, and implemented it… now what? Now it’s time to analyze the success of the collaboration within the context of your marketing strategy to determine whether it helped achieve your goals. But how do you measure the success of an influencer campaign?

One metric you definitely need to consider when measuring success is return on investment — or ROI. In influencer marketing, it’s often referred to as ROIS (Return on Influencer Spend). Below, we’ll take a closer look at what ROI means in influencer marketing, how to calculate it, and how you can improve it.

What is Influencer Marketing ROI?

ROI describes the profitability of your marketing campaign. Alongside other key performance indicators (KPIs), ROI helps determine whether the budget you’ve invested in influencer marketing is paying off, for example, in the form of increased sales.

The term ROI comes from business administration and literally means “return on investment.” It compares the revenue generated with the expenses incurred and multiplies the result by 100. The resulting percentage becomes a business metric that indicates whether an investment was worthwhile. As you can see, ROI — or ROIS in the context of influencer marketing — tells you whether your influencer campaigns have been profitable. It goes without saying that every company working with influencers should measure its ROI.

Success in Influencer Marketing? Calculate the ROI

The basic formula for ROI is:

(Revenue ÷ Costs) x 100

So, divide the revenue generated by the amount invested and multiply the result by 100. For example, imagine you invested €10,000 in a campaign with a major influencer. The campaign generated €50,000 in revenue. Divide 50,000 by 10,000 and multiply by 100 — your ROI is 500%!

ROI can be positive or negative. The 500% in our example is clearly positive: the revenue far exceeds the investment. A negative ROI, meaning a percentage below 0 (e.g. -20%), means you spent more than the campaign brought in. A negative ROI should be avoided at all costs; a positive ROI is the goal. The higher, the better — a 500% ROI is an excellent result and likely indicates you chose the right influencers. Some highly successful companies even achieve 2000% ROI ^[1] with influencer marketing!

Once you’ve calculated your ROI, you can use it alongside other KPIs to assess whether your influencer marketing strategy is working. That’s the ultimate goal of measuring success: evaluating the effectiveness of your strategy to identify opportunities for improvement.

Steps to Analyze an Influencer Campaign

1. Set a Budget

Even before negotiating with your first influencers, you should define a clear budget:
How much are you willing and able to invest in influencer marketing this year, this quarter, this month? And accordingly, what’s your maximum budget for a specific collaboration?

The budget should be part of your overall marketing budget and ideally defined the previous year. This way, you avoid the temptation to overspend just to get a certain influencer as your brand ambassador. While your strategy shouldn’t be entirely limited by your budget (adjustments are often necessary mid-year), a rough framework is important. Your influencer marketing efforts will naturally depend on your budget — and that budget will directly impact the revenue you can generate from influencer partnerships.

2. Define Your Goals

To decide whether ROI is a suitable performance indicator for your influencer marketing, you first need to determine the campaign’s goals.

• If your main goal is brand awareness, ROI is not particularly relevant — other success metrics are more important.
• If you want to increase website or online store traffic, then traffic metrics are most relevant.
• But if your goal is to increase sales, then ROI becomes especially important.

Here, we also distinguish between soft goals and hard goals:
Soft goals such as brand recognition, brand perception, and engagement are no less important than hard goals like sales or traffic. Ideally, your influencer strategy achieves both, but some goals will need to take strategic priority.

3. Determine Key Metrics

This step is fundamental when measuring success. As mentioned, the right metrics (KPIs) depend on your goals. Choosing the wrong ones can lead to misleading or inconclusive insights.

Here are some key KPIs relevant to different goals:

If your goals are to increase downloads, newsletter signups, or social media followers, then these metrics are your most relevant KPIs over time.

Social media also offers unique KPIs to track. One notable metric is Earned Media Value (EMV) — an estimate of the media value generated by a collaboration. It reflects what it would cost to achieve the same results with a paid advertising campaign.

4. Define Your Marketing Strategy

Based on your defined goals and available budget, you can now start developing your influencer marketing strategy. You should be clear on your target audience and choose the right influencers for collaboration. Next, decide what kind of influencer campaign you want to run, reach out to influencers, and negotiate.

It’s always a good idea to have a concrete marketing strategy so you don’t lose sight of your priorities. Strategic planning ensures you’re able to measure success accurately later on and adapt based on clear, data-driven analysis — not just gut feelings.
