Viewability

Viewability is an online advertising metric that aims to determine only impressions that had the opportunity to be seen by users. For example, if an ad is loaded at the bottom of a webpage but a user doesn't scroll down far enough to see it, that impression would not be deemed viewable. Viewability is not a measure of ad effectiveness.

Viewable impression

In online/digital media, a served ad impression can be only be classified as a “viewable impression” if the ad meets all of the following criteria: it was contained in the viewable space of the browser window, it is in an in-focus browser tab, and it meets pre-established minimum percent of ad pixels within the viewable space and the length of time the ad is in the viewable space of the browser. It is recognized that an “opportunity to see” the ad exists with a viewable ad impression, which may or may not be the case with a served ad impression.

Viewable Impressions

A digital ad that had the opportunity to be seen, sometimes referred to through the traditional print media term of being “above the fold”. The current industry criteria for a standard ad unit to be considered viewable is that 50% of the canvas was within the consumer’s rendered window for a minimum of 1 second – the time required for a consumer to understand that the unit is a piece of advertising. Viewability is not a measure of ad effectiveness.

Virtual Reality (VR)

AR / VR

An experience that is made to be significantly more immersive than standard video assets. VR allows a user to be completely immersed into an environment of the marketer’s choice. Ads within VR must occur within either a designated ad space (such as a street side billboard), as a video (that might play in a virtual home TV or virtual movie theater), or as an object (such as a branded bag of crisps on the table).

Virtual room

AR / VR

A virtual reality native ad format in which the viewer can choose to enter a room filled with sponsored advertising content. Key components of a virtual room include the environment (the world the user sees in the room), the objects (interactive 3D, 2D and 360 video ads, audio tracks represented in the room), and interactions (produces a transition to another part of the scene or introduces new visual or interactive element).

Visibility

DOOH

The area of research that, using eye-tracking methods, produces data on the probability that an advert is visible to the viewer.

Visibility area

DOOH

The area around a frame in which it can be seen. It incorporates the maximum visibility distance of the frame, and the angle that Route has defined to mark its catchment area (120°).
