Match each campaign goal with the appropriate optimization type.

The question asks to match campaign goals with optimization types, implying a direct correspondence. Each option represents a distinct campaign goal and its associated optimization metric. 1. Detail page view (DPV): This goal focuses on driving traffic to a product's detail page. Optimizing for DPV means the system will prioritize showing ads to users most likely to view the product page, indicating interest in learning more about the product. 2. Pixel conversion: This goal is broader and involves tracking specific actions on a website using a conversion pixel. Optimizing for pixel conversion means the system will aim to deliver ads to users most likely to complete the defined action (e.g., add to cart, sign up for a newsletter, download a brochure), which goes beyond just viewing a page. 3. Purchase: This is a direct response goal, aiming to drive actual sales. Optimizing for purchase means the system will target users most likely to complete a transaction, directly impacting revenue. 4. Click: This goal focuses on driving users from the ad to a specified landing page. Optimizing for clicks means the system will prioritize showing ads to users most likely to click on them, increasing traffic to the destination.
