Demand Gen: creating one clear campaign-building experience across Google’s most visual surfaces.

I led the end-to-end UX architecture for a new campaign construction experience spanning YouTube, Discover, and Gmail—bringing AI-powered tools, insights, and performance workflows into a more cohesive system.

The opportunity

Deliver a campaign construction experience that optimized for image and video campaigns in a familiar way.

The work required us to reimagine the decades-old experience to build ad campaigns for Google. Originally focused on text based search ad campaigns, Google Ads did not offer advertisers a way to build image and video based campaigns, which were key to growth for YouTube, Gmail, and Google Discover ad surfaces. The goal was to deliver a comprehensive experience with terminology and campaign hierarchy that felt familiar to social first advertisers.
