What Is Demand Gen and Why It Replaced Display
Google Demand Gen (formerly called Discovery) was fundamentally rebuilt in 2024 and reached full maturity in 2026. It now covers four distinct placement environments that share one defining characteristic: they reach logged-in Google users who are consuming content, not searching with intent.
YouTube In-Stream & Shorts
Pre-roll and mid-roll ads on YouTube videos, plus native ads within YouTube Shorts. In 2026, Shorts placements in particular are significantly underpriced relative to their engagement rates — the algorithm is still learning to value them fully.
Gmail Promotions & Social
Ads in the Promotions and Social tabs of Gmail — reaching users with demonstrated commercial intent (people who open promotional emails are categorically more purchase-oriented than the average web user).
Google Discover Feed
Native-format ads in Google's personalised content feed on Android and iOS. Discovery audience targeting is interest-based and predictive — Google infers interests from search history, YouTube watch history, and app usage patterns.
Logged-In User Advantage
Every Demand Gen impression is served to a logged-in Google account user. This means identity-based targeting (not cookie-based), better attribution accuracy, and access to Google's richest behavioural and intent signals. GDN publisher sites target often-anonymous users with cookie-based data that degrades daily in cookieless browsers.
