Default image impressions are not relevant for over-the-page and transitional ads.
In the following cases, a default image is displayed instead of the primary asset:
- In certain cases, Flash Player is not installed on end users' machines. The Sizmek platform uses special scripts to detect Flash Player on the local machine.
- In certain cases, end users utilize Opera, and the Sizmek platform does not support displaying rich media ads. This is identified through the use of special scripts to detect the browser in use.
The Sizmek platform mandates the inclusion of default image for each banner ad created in the system. This way, we ensure that the user experience will remain positive and that the structure of the page is not affected.
