How Do You Search For What People Are Buying Online & Not Just Niches!

There are companies out there spending thousands doing what you want to do. Why not piggy-back on their research?

For the African-American market, I'd start with the BET channel. For the Latino market, check out Univision, Telemundo, etc. Plug those sites into Quantcast, etc. for demographics.

Or get a bit more granular. Look for specific shows tailored to women on those networks, and look at what products are consistently advertised.

Do the same with magazines. Go to the library and grab a year's worth of any magazine catering to women in those groups. Page through and make a note of every product type advertised, then add a tick mark for every time you see an ad for that kind of product.

Now head to Facebook or Pinterest (or both). Start at the pages of companies you found in your earlier research. Scan the timeline or boards looking for likes and engagement, then follow the link back to individual people's pages and look for what else they like. Do the list and tick mark exercise again.

Depending on your available time and diligence, within a week or so you should have the answers to your question.
