Your question is Ranking Test for App Discovery. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
You work on an app marketplace team and have built a new ranking algorithm for the store's search and recommendation surfaces. You want to understand whether the new ranking improves app discovery and installs without hurting downstream user experience or marketplace health.
How would you set up an A/B test to evaluate the new ranking algorithm, and what metrics would you track to decide whether to launch it?
