It comes as a new conversion action and is for reporting only. Google announced it last year as a way to measure brand uplift without paying for a Brand Lift Study.
How it counts:
It tracks searches a user makes within 7 days of seeing an eligible ad
It uses last click, view-through attribution, so only the last ad the user viewed gets the credit, even if more campaigns were involved
Supported campaign types: YouTube and Demand Gen. It does not work with Performance Max.
