A lack of clicks doesn't automatically signal failure if awareness is being generated. Brand search lift, assisted conversions, and recall studies help capture that hidden impact. Tracking increases in people searching the brand after exposure shows intent development over time. Attribution models can connect display impressions to later searches even without immediate interaction. If those signals rise, the campaign is building demand rather than failing outright. Still, weak click-through rates might indicate creative or targeting issues worth refining. So success is broader: not just clicks, but how much the brand memory grows.
