In an opinion column, Shirley Marschall examines two ways that premium ad inventory can degrade: contamination (bad actors entering the supply chain) and convergence (independent publishers adopting aggressive monetisation due to economic pressure). She cites Adalytics' research showing MFA inventory appearing in PMP deals, and a case from T-Mobile's Noam Gissis where a premium news site crashed browsers, raising questions about MFA red flags emerging outside MFA sites. The article highlights Google's new experimental CrUX ad metrics (Ad Count, Ad Density, Ad Weight by CPU, Ad Weight by Network) as a browser-based measurement layer for inventory quality, which could help advertisers assess user experience beyond supply path.
