Stickers are voluntarily selected and sent by customers, making them different from passive advertising. Their value depends on activation, repeat use, positive reception, and measurable downstream behavior.
Track installation, activation rate, repeat-use rate, estimated earned exposure, brand recall, and assisted conversion. Use campaign codes or tagged links and, where possible, a comparison group.
A simple ROI compares incremental contribution margin with the full cost of production and distribution. High downloads with low activation indicate weak relevance; frequent use without recall suggests that brand cues are too subtle.
Useful everyday expressions should dominate the pack. Measurement then guides which designs to retain, replace, or expand.
