Should I build Maars around shopping help or public Q&A?

If you’re choosing one to start with, I’d build Maars around Shopping Help first.

Why: it usually gives you a cleaner path to value because users arrive with a clear intent, the experience can be easier to understand and validate, and it may be simpler to prove usefulness quickly. It can also be easier to monetize directly if the product connects to purchases, leads, or referrals.

I’d choose Public Q&A if your main goal is to build a community-driven product and a library of user-generated content over time. That can support repeat engagement and search discovery, but it often takes longer to gain traction, and moderation, spam, and quality control become important.

A practical rule of thumb:

• Pick Shopping Help if you want faster validation and a more direct user problem to solve.
• Pick Public Q&A if you want community growth, long-tail content, and are prepared to manage moderation.

One caveat: if your shopping experience depends on real-time pricing or inventory, that data can be hard to maintain accurately, so you’ll want to verify how fresh and reliable your sources are.
