If someone quotes you one exact number for AR's conversion lift, walk away. Published case studies report a wide range, and honestly the range is the useful part. - Category explains most of it: will-this-fit converts differently than does-this-shade-suit-me. - Implementation quality explains the rest. A janky 3D model can convert worse than good photography. - The pattern I trust: AR lifts most where purchase anxiety is highest, big-ticket, fit-sensitive, painful to return. - Where anxiety was low, the lift is small, because there was less friction to remove. - The novelty curve is dead. Early AR got taps just for being new. That free attention is gone, which is healthy. - Build your business case on category-level numbers, not one famous case study. ModelSnap produces the 3D model and AR preview file, $4.99 per HD model.
