The type and amount of statistics and analytics provided by an OVP is a critical selection criteria. Veeple is an OVP that features clickable hotspots in the video. Here’s a short (under 3 minutes) video of Veeple’s viewing analytics that I found useful in understanding the type of information that they supply. I’m sure most OVPs supply most of this falloff and geographic data, though Veeple is one of the few with clickable interactivity.
I hope you find this useful.
