Measuring impact
Yokaify holds out a slice of traffic so you can see true causal lift, not vanity metrics.
The holdout group
For a fraction of visitors who would have triggered an intervention, Yokaify logs the moment but deliberately stays silent. These visitors form a control group.
Why it matters
Most tools only show you what happened to people who used them — which mixes up correlation and cause. By comparing visitors who saw the mascot against the holdout who didn't, Yokaify isolates the causal lift: the conversion difference the mascot actually created.
Nothing to set up
The holdout and outcome logging are built in. As outcomes accumulate, your dashboard reflects the measured difference between the two groups.
