You're the proprietor of a small candy shop and want to learn about customers' journeys from ad engagement to in-store visit. Which metric should you use?

Local Actions is the most appropriate metric because it specifically tracks user engagement with ads that lead to physical store visits or other local actions, such as calls or direction requests. This metric directly measures the effectiveness of your ads in driving offline customer behavior, which is precisely what you want to understand for your candy shop. Store Sales would only tell you the final purchase amount, not the journey from ad engagement. Store Visits provides a count of visits but doesn't directly link them to specific ad interactions. Ad Actions measures general engagement with the ad (clicks, impressions) but doesn't confirm an offline outcome.
