RecruitJet is a business focused on improving their conversion rate optimization. Tasked with deciding which projects within RecruitJet are worth testing, Keaton is using the PIE framework to help make that decision. Which of the following questions would fit in with the PIE framework criteria?

The PIE framework (Potential, Importance, Ease) helps prioritize optimization projects. "How valuable is the traffic to this page?" aligns with the 'Importance' criterion, as understanding traffic value directly impacts the potential return on investment for any optimization efforts on that page. If traffic is highly valuable (e.g., high-intent users), optimizing that page becomes more important. The other options don't directly fit the PIE framework's prioritization criteria: "Why is one Google Ads campaign performing better than another campaign?" is an analytical question about performance, not a prioritization question for optimization projects. "Can the click-through rate be further improved for this ad?" is a general optimization question, but doesn't address the importance or potential of that improvement in the broader context of other projects. "Why is the majority of traffic to the site coming from mobile devices?" is an analytical question about user behavior, not a project prioritization question.
