Finding niche in dropshipping.

For some reason I've always had problems finding KW and niches. after long struggles I learned to find profitable KW.

But now I'm looking to start a business as a dropshipper.

Can someone recomend me a good method or tutorial on how to find good niches for dropshipping business.

I'm looking for niches where products cost between 200$-1000$.

Keyword research and niche identification are the same for ecommerce and affiliate marketing. Try looking on amazon on some of their best sellers and check their reviews to get an idea.
