67. How should I go about interviewing my clients to get the right content I'm looking for?

Question:
I interact closely with my clients a lot whether by phone, conference call, or over messages. I also used to do phone sales enrolling the clients I now work with and I have a Facebook group of about 6k members (clients and prospects) that I engage with daily.

Hell, I even used to be a hopeless, clueless single guy myself. (I help single guys build social confidence and land a high-quality girlfriend)

I'd say I understand my market a fair deal.

So I'm wondering when it comes to me doing the research part, would it be beneficial to look at forums and Amazon as well as interview my clients one one one?

I'm guessing yes and I've interviewed many of my clients before, I'm just wondering how I should go about filling out my research page given the resources I have available.
