Video stuffing is when a fraudster runs video ads that look legitimate on the surface, but load a large number of video ad tags or fire additional video ad impressions in the background, which are never visible to the end-user.
In this kind of malvertising attack, the bad actor is filling your webpage with unseen video advertisements in order to rack up ad impressions and rake in revenue.
In theory, this keeps your user experience relatively the same visually by not bombarding users with ads. But in practice, it causes a few major problems. First, it defrauds the advertiser by charging them for ads that are intentionally not being viewed, resulting in poor ad engagement metrics, which can ultimately bring down your yield. Second, these ads use your website’s resources to load multiple videos, causing a huge reduction in site speed (which has serious effects on user experience).
In this article, we are going to focus on an often hidden issue, video stuffing, and tell you how to protect your site and your users from this form of malvertising.
