Assessing Compliance in Digital Advertising: A Deep Dive into Acceptable Ads Standards

Abstract

Online ads provide essential revenue for millions of websites but often disrupt user experience. To address this, browser extensions emerged to block intrusive ads, prompting the creation of the Acceptable Ads Standards to balance user choice and monetization. The Acceptable Ads Standards, initiated by the Acceptable Ads Committee, seek a balance between user experience and ad effectiveness, allowing certain non-intrusive ads determined by size, placement, and type limitations. This paper analyzes the compliance ofdigital advertisements with the Acceptable Ads standards by examining 10,000 popular domains intersecting Tranco’s top 100K andthe Acceptable Ads exception list. Our findings reveal that nearly 10% of these sites display non-compliant ads on landing pages, exposing design flaws in the exception list that allow publishers to bypass size and format restrictions. We propose enhancements to the exception list to better uphold user experience and ad integrity.
