How can I improve user engagement and retention on Health e Happy?

Hello Support Team / Community,

I’m currently working on Health e Happy (https://healthehappy.com/
) and would like guidance on increasing user engagement and retention for the site. Specifically:

What strategies have proven most effective for improving repeat visits and return users on health/wellness content sites?

Are there particular features or tools (e.g., personalized recommendations, push notifications, user accounts) you would recommend implementing first?

What metrics should I track to best measure engagement success and when should I consider optimizing new features?

Any links to best‑practice guides or case studies would be very helpful!

Thanks in advance!
