Mario has a tight budget for his campaign and wants to make sure his targeting is set up to get him the best ROI possible. What feature can Mario set up in DoubleClick Search to automatically detect high-performing geographic areas?

Adaptive geo-targeting in DoubleClick Search automatically optimizes bids and targeting based on the performance of different geographic areas. This helps Mario maximize his ROI by focusing budget on locations that yield the best results. RLSA (Remarketing Lists for Search Ads) targets users who have previously interacted with a website, not geographic areas. The "Health panel geo tab" is a reporting feature, not a targeting mechanism. "Portfolio geo-bidding" is not a standard DoubleClick Search feature; portfolio bidding applies to groups of campaigns or keywords, but not specifically to geographic targeting in this automated way.
