If an ad is out of view, it can’t reach its full potential
For digital ads to make an impact, they need to be seen — not just served. However, as many as one-third of digital ads go unseen by consumers in certain environments. Make sure your ads have the opportunity to be seen by real people wherever they are.
Give ads the spotlight they need with our toolkit.
Our viewability solutions cover:

Advertising can’t be effective without first being seen
Marketers need to reach the right consumers, in the right places, in the appropriate context. But before that can happen, ads need the opportunity to be viewable. Even after an ad loads, the environment or consumer interaction can interfere with the viewability. We ensure your ads receive Quality Attention™. After all, we know making a connection takes longer than one second.
Viewability continues to be a top concern for marketers
Viewability remains the bedrock of media quality assurance. As digital advertising becomes more sophisticated, media buyers and sellers want to not only prove their ability to drive results, but they also want to transact on viewability — making it a customizable currency.

Ad viewability is the ability for a digital ad to be seen by an actual consumer. To be considered viewable, an ad must meet the minimum guidelines set by the industry, and should not include illegal bot traffic and other forms of ad fraud as part of the number of viewable impressions. Viewability does not describe how effective an ad was, whether it was seen by target audiences, or if a consumer actually looked at it.
The Media Rating Council defines viewability as 50% of the ad’s pixels visible for at least one second (display) or two seconds (video).
Ad viewability is calculated by dividing the number of viewable impressions by the total impressions served and multiplying by 100. For example, if 1,000 impressions are served and 700 meet the viewability standards, the viewability rate is 70%.
70% viewability means that 70% of the ad impressions served met the criteria to be considered viewable, as defined by industry standards or an advertiser’s custom viewability standard. It indicates the percentage of ads that were likely seen by users, providing a measure of campaign effectiveness.
An ad view refers to an instance where an ad has met the minimum criteria to be considered viewable by a user. It provides a baseline for assessing whether the ad had the potential to make an impact.
Ad visibility can be improved by optimizing ad placement, using high-quality creative, targeting the right audience, and leveraging technology like IAS Viewability solutions. These steps ensure ads are placed in prominent locations to drive greater viewability.
Viewability is important because it measures whether an ad has the chance to be seen by its audience. High viewability rates indicate effective ad placements, which lead to better engagement, higher ROI, and stronger campaign performance.
