Viewability

What is viewability?

Viewability measures whether an ad had a real chance to be seen: on screen, sufficiently visible, for long enough. The common standard counts a display ad as viewable at 50 percent of pixels on screen for one second, two for video, a deliberately low bar.

Why it exists

An impression is counted when an ad is served, not when it is seen. Ads load below the fold, in background tabs, under other elements, or on pages abandoned before rendering. Without viewability measurement, reports happily count exposure that never touched a human eye.

Why it matters

Unseen impressions are pure waste with perfect reporting: the money is spent, the metric ticks up, nothing happened. Buying on viewability, and verifying it independently, is basic hygiene in display and programmatic, where inventory quality varies from premium to fraudulent.

The honest view

Viewable is the floor, not the goal: an ad technically on screen for one second has been seen the way wallpaper is seen. Treat viewability as a filter that qualifies impressions, then judge campaigns on attention and outcomes, engagement, lift, incremental sales. Pay for the chance to be seen, optimise for actually being noticed.
