Doreen uses Google Search to reach customers as they search for products similar to hers. She'd like to create a Display Remarketing campaign to reconnect with users and increase sales. How might remarketing help her meet this marketing objective?

Remarketing in Google Ads specifically targets users who have previously interacted with your website or app. By showing ads to these users as they browse other websites or use apps on the Google Display Network, Doreen can re-engage them and encourage them to complete a purchase, thus increasing sales. The other options describe different targeting methods: "TV-like audiences" and "holistic picture of their lifestyles" refer to affinity audiences; "audiences who differ from those on an original remarketing list" contradicts the purpose of remarketing; and "specific audiences based on declared data" is too broad and doesn't capture the core mechanism of remarketing.
