Influencer Marketing ROI in gaming: The Only Four Numbers That Matter
An influencer campaign report with fourteen metrics on it is usually hiding the fact that the four that matter are not there.
Quick answer
In gaming, influencer marketing ROI comes down to four numbers: cost per verified signup (verified signup), deposit value in the first 30 days, share of verified signups still active at day 30, and cost per verified signup by creator. Everything else, including reach, engagement rate and views, is diagnostic. Useful for explaining a result. Never the result.
The four numbers
1. Cost per verified signup
Total campaign cost divided by verified signups attributed to it. This is the number the brand is actually buying, and it is comparable across channels in a way that no engagement metric is.
2. First 30-day deposit value
Two campaigns can produce identical verified signup counts and completely different revenue. A creator whose audience deposits the minimum and stops is not equivalent to one whose audience deposits and continues, and only this number separates them.
3. Day-30 retention of acquired players
The metric that exposes the campaign that looked good in week one. Acquisition through a creator whose audience came for a giveaway retains differently from acquisition through a creator whose audience came for the game.
4. Cost per verified signup by creator
The aggregate hides the useful information. In a roster of twenty creators, the distribution is rarely even, and the point of measuring per creator is to know who to keep for the next title.
Why the usual metrics mislead
| Metric | What it actually tells you |
|---|---|
| Views | The video was served. Nothing about intent |
| Engagement rate | Comparable only within the same creator, over time |
| Follower count | The size of the audience, not its relevance |
| Clicks | Useful only if the funnel after the click is measured |
| CPM | The cost of being seen, which is not what you are buying |
None of these are useless. All of them are upstream. The failure mode is reporting on them because they are large and available, while the four that decide the budget are not being collected.
The measurement problem nobody mentions
Attribution in gaming creator campaigns is genuinely hard. The player sees the stream on one device and registers on another, often days later. Link tracking captures a fraction.
Which means: the honest report includes the attribution gap, rather than presenting the tracked number as the whole result. A campaign that reports 200 tracked verified signups and states that tracked coverage is partial is more useful than one that reports 200 and implies that is the total.
