It is well known that digital ads violate privacy, yet we know little about their content. Digital ads are of increasingly low-quality, and often contain manipulative and deceptive components to lure users into viewing potentially harmful content. Such harmful content can range from disinformation or hyper-partisan websites all the way to products with questionable claims/value like health products or payday loans. Further, many such types of ads appeal to vulnerable populations like children, older adults, and low-income individuals—all of which calls for more public scrutiny into their content. However, owing to their fleeting nature, digital ads are neither archived nor systematically studied. Previous studies of digital ads have been small in scale and limited to a single point in time.
