Jerry wants DoubleClick to automatically adjust keyword bids based on the dollar value of Ultimate SnowShoes products that users have researched. What feature allows him to do this?

RLSA (Remarketing Lists for Search Ads) allows advertisers to tailor their search campaigns based on users' past interactions with their website or app. In this scenario, Jerry can create an audience segment of users who have researched Ultimate SnowShoes products. Then, he can use RLSA to adjust bids specifically for these users when they search on Google, increasing bids for those who have shown higher intent or researched higher-value products. Adaptive geo-targeting adjusts bids based on location, not user behavior on a website. Portfolio bidding optimizes bids across a group of campaigns or keywords to achieve a specific goal, but it doesn't directly use website interaction data in this granular way. Programmatic remarketing typically involves displaying ads on other websites or apps, not adjusting bids on search engine results pages.
