How do we find out niches online?

I'm ok but the fact that I settle for a life less important and have no contribution on the human species won't work.

I know that their is niches everywhere and all you have to do is write something that people are looking for. 

I've got tons of traffic off one niche and it ain't enough but the idea that you can really write a post to get out of your job, what does that mean to you?

I write a post How to market your auto dealership, a big post online with qr codes and sms, mms and seo and bluetooth and anything in between.

People are ranking websites and running ads.

They are also sending you notifications in the notification bar on your phone. 

People let's do this. 

That means that we have no inventory for people that aren't working hard enough on their phone and put the time in and rank websites and even write stories and use the app market.

That means big opportunity for marketers and working the phone to the ground and get paid.

What type of pages are you already ranking and getting traffic. Maybe that's your niche. 

But the idea that we can send notifications out and finding buyers and understand how the phone works.
