How to find Unsaturated Niche?

[adidam]

Hey There,

I am into PPD and CPA. I am almost member of every BH and IM forum so I always keep myself updated with every method.

The thing which I am not able to find is Unsaturated Niche?

How can I find out uncommon niches which I can promote easily and earn from CPA and PPD?

Current strategy

Youtube >> Landing Page >> Cleanfiles

Thanks
