Paid to Look Like Truth: The Prevalence and Dark Patterns of Advertorials in News Outlets
Abstract
Advertorials represent a marketing strategy where advertisements are designed to resemble the style and tone of editorial content. Despite their appearance, they are, in fact, paid content intended to promote a product, brand or service. Studies indicate that advertorials are more effective (81%) and less intrusive than traditional banner ads or pop-ups. Despite regulatory efforts for clear disclosure of paid content, concerns persist about the deceptive nature of advertorials. Advertorials can mislead readers into believing that they are consuming unbiased editorial content. In doing so, they gain undeserved legitimacy, by draping themselves in the credibility of the publication's design. In this study, we conduct the first systematic large-scale study of advertorials. We propose a novel automated methodology for detecting problematic advertorials in the wild, and collect 186K ad URLs over a period of 5 months. We investigate their prevalence and explore their structural and linguistic characteristics, finding that advertorials appear in 1 out of 3 news websites, including popular and credible outlets (e.g., The Guardian, EuroNews, CNN). Additionally, they often exhibit behavior associated with malicious practices and deliberately obscure or make legal disclaimers difficult to recognize, preventing users from identifying the promotional nature of the content.
