Not all user pageviews on your site convert into a video ad impression. In fact, the following things can happen:
- the user viewing your site has an adblock extension installed
- the code hasn't been embedded correctly
- the bounce rate of your site could be very high, or the user's time on page is so low it doesn't allow the player to load
- the Unit is inserted in a point of the page where it cannot convert (for example it's positioned too low in the page)
Additionally, remember that not all requests sent by a Unit become Impressions, since our player only delivers advertisements that are relevant to your site's audience.
