Which of the following are insights an advertiser could see only after implementing the Pinterest tag?

The Pinterest tag, a piece of JavaScript code, tracks user actions on an advertiser's website. Without it, Pinterest cannot gather specific data about user behavior post-click. Therefore, to see when a user visited sale items, the specific product details (like color or size) added to a cart, or the time taken to purchase after seeing an ad, the Pinterest tag must be correctly implemented. These insights are crucial for optimizing campaigns, understanding user journeys, and improving return on ad spend, as they provide detailed conversion and engagement data that Pinterest's platform alone cannot infer.
