A business owner's objective is to increase profit from their eCommerce website by promoting their most profitable products. Which set of metrics should they track in Google Analytics to measure progress toward this specific goal?

The relevant set is product page views, popular items, and purchase revenue. The objective is product-level: identify the most profitable items and sell more of them. Those three metrics form a chain that can actually be acted on — how many people see each product, which items are selling, and how much revenue each generates — so the owner can spot profitable products with low visibility, or heavily viewed products that rarely convert. This illustrates a principle the exam returns to: metrics should be chosen from the objective, not from what happens to be available. App downloads suit an app business, lead metrics suit a lead generation business, and technical attributes like browser and operating system describe the audience without measuring progress towards profit. Where margin data exists, importing it makes the analysis genuinely profit-based rather than revenue-based.
