Google's Demand Gen now applies view-through conversion optimization to video assets only — images demoted to reporting
Published August 17, this update restricts VTC bidding to video assets exclusively (image view-throughs stay in reporting but are no longer biddable), expands VTC inventory from YouTube + Discover to Display, and shifts Display video billing from CPC to CPM — making VTC optimization the default for all new Demand Gen campaigns.
Why it matters: Video creative is now the only format driving biddable view-through attribution in Demand Gen — a concrete measurement argument for any team still questioning whether video production is worth the investment over static.
