What's a good ROI for influencer marketing at an event?

There's no universal number — it depends on the campaign goal, the industry and the type of event. Rather than comparing yourself to an “average,” it's more important to track your own progress over time and compare cost per contact across collaborations.

How can I track results if the influencer doesn't share post statistics directly?

Agree on a unique promo code or a tracked link for each collaboration in advance. This lets you attribute specific conversions to a specific creator even without direct access to their analytics.

Is it worth investing in influencers with larger reach, or several smaller ones?

It depends on the goal. For building awareness, larger reach can help; for targeted conversion, combining several smaller creators with a high engagement rate within a precisely defined target audience often works better.

How to Measure the ROI of Influencer Marketing at Events

7 min read · 2. 9. 2026

Investing in influencer marketing at an event is easy to spend money on — proving its return is harder. Without a clear measurement framework, ROI stays just a feeling of “it worked” or “it didn't work.” In this article, we show you how to set measurable goals and properly evaluate a campaign.

1. Set a goal before the campaign starts

ROI can only be calculated if you know what you're actually measuring. The goal might be building awareness of the event, ticket sales, registrations for next year's edition, or quality content for future use. Each of these goals calls for different metrics and a different type of influencer.

2. Distinguish reach from actual engagement

Follower count says very little about how many people actually saw the content and reacted to it. Track the engagement rate — the ratio of comments, saves and shares to reach — because this metric better predicts the real impact of the collaboration.

3. Calculate cost per contact, not just the total amount

Compare collaborations by cost per thousand impressions (CPM) or cost per engagement (CPE), not just by the total invoiced amount. A creator with a higher price but significantly higher engagement can end up cheaper per unit than a cheaper but passive collaboration.

4. Measure conversions through links and promo codes

Since no platform lets you automatically track the performance of published content without access to the creator's account, agree on a unique promo code or a tracked link for each influencer in advance. This lets you attribute specific sales or registrations to a specific collaboration.

5. Factor in influencer quality, not just size

Two creators with the same follower count can have very different audience quality, authenticity and engagement rates. That's why at EventPixel we use the AI Match score when selecting from the influencer database — a composite indicator built from nine sub-scores, including audience quality, engagement and brand fit, which helps you narrow down your choice even before the first contact.

6. Don't forget the value of the content itself

Part of the return is the content that remains after the campaign — with the creator's consent, you can reuse photos and videos in your own communication. This value is admittedly harder to quantify, but it shouldn't be missing from your ROI calculation.

7. Evaluate the campaign comprehensively once it's over

After the event, compare all metrics against the goal you set at the start, not just against the results of competing collaborations. Write down your findings for future campaigns too, so that over time you can more accurately estimate which type of influencer and format delivers the best cost-to-result ratio.

At EventPixel, the influencer marketplace and the AI Match score help you pick the right creators from the start, open campaigns on the platform make it easier to reach interested creators, and a clear portal gives you solid grounds for evaluating the return on every collaboration.
