When we record a impression or play on your video but are unable to determine the device, location, or website where it originated, we count it toward your total stats under "Unknown."
Unfortunately, there's nothing we can do to recover additional data from those visits. It simply isn't available to us!
If you've set up domain-level privacy, we can assure you that any stats listed as "Unknown" are only coming from the domains you've chosen to allow.
Ultimately, when it comes to displaying stats for your videos, we give you as much information as possible. If we didn’t include "Unknown" stats, you wouldn’t know how many people visited your video.
