Making YouTube's Home recommendations relevant for infrequent viewers

You are a product manager at Google working on YouTube. The team wants the Home feed to feel more personal for casual viewers. What approach would you take? ```hint Start from what Home knows Consider how little the system may know about someone who opens YouTube only now and then, and which signals you could collect or infer without asking that person to do much work. ``` ### Clarifying Questions - How should casual viewers be defined: people who visit rarely, people with little watch history, signed-out viewers, or people who mostly arrive through links shared elsewhere? - Is success more frequent return visits, more satisfying visits when they do come, or turning casual viewers into regular ones? - Which surfaces are in scope: the mobile app, the website, the TV app where a household may share one account, or all of them? - Should Shorts appear on Home for this group, or is the focus long-form videos? ### What a Strong Answer Covers - A precise definition of the casual viewers chosen, why they matter to YouTube, and how their needs differ from heavy viewers' - A diagnosis of why the current Home feed underserves them, such as sparse or outdated history, shared devices and changing intent - Product and ranking ideas that work with little data, prioritized, with a clear first bet - Success metrics centered on satisfaction and return visits rather than raw watch time, with guardrails for content quality, privacy and creator diversity - Experiment design and risks such as overreacting to a single click or narrowing what people see ### Follow-up Questions - How would you personalize Home on a living-room TV where several family members watch under one account? - If a viewer is signed out or has paused watch history, what can Home still show that feels relevant? - How would you tell whether a casual viewer's light use is a problem to solve or simply how that person wants to use YouTube?
