Accurate statistics are not always recorded using Vimeo’s methods of tracking loads and views. Vimeo videos viewed via a third-party player do not always record statistics in the same way that videos viewed via their direct link in a web browser are counted. If we view your project using the Vimeo app on another streaming device (such as Apple TV or Roku), it is also being viewed via a third-party player. The vast majority of the films submitted to us are viewed in this manner, and therefore the statistics are not counted in the same way that they would be watched via a direct link. This is outlined directly in Vimeo's own online documentation, the text of which is included below:
"What stats does Vimeo record if my video is displayed using a third-party player?
Unfortunately, there isn’t very much data we can gather from views that don’t occur within the Vimeo player. For PRO, Business, Premium users using third-party player links, we can only approximate the number of times the file is being played. Multiple impressions / plays by the same viewer in the same browser session will not be counted (like they are when our own player is used). We also cannot count finishes or any engagement / duration stats for these plays. In many cases, we will still be able to detect the website where the view is happening, the location of the view, and the device, however, this is less reliable than it would be with our own player."
