If Kitchen Smart's business goal is to increase sales in the Amazon store, which advertising metrics will help them measure performance?

The correct answer is "Return on ad spend (ROAS)." Return on ad spend (ROAS) is the most effective metric for measuring performance when the goal is to increase sales in the Amazon store. ROAS calculates the revenue generated for every dollar spent on advertising, providing a clear indicator of how well the ad campaign is driving sales. A higher ROAS means the campaign is effectively converting ad spend into sales, which directly aligns with the objective of increasing sales. While detail page views and clicks are useful for measuring engagement and traffic, they do not directly assess the financial return from the campaign, making ROAS the most relevant metric for tracking sales performance.
