We are running a store selling toys and robotics sets. Today I got an email from a service offering us to integrate with them and to show "3D models and building instructions" for the toys and the robotics sets. They are claiming at least 0.15% increase of conversions with examples of 1-2%. I would generally just try it for a month or two and measure it, but as they still don't have models and building instructions specifically for our products we would have to put some money upfront to develop them or wait months, probably years until they develop them.
My question is do you have experience with 3D on your webstores? Are these real numbers? Has anyone tried something similar?
