There's several ways to find a niche that you might want to use.
You don't have to choose a specific catagory, basically every time there is a problem, a niche would be the key.
Try and think up for some ideas, that you've had some problems with, or you've seen people have problems with.
Once you've brainstormed on this, you should have a few niches that you want to go and research in-depth (I will be covering that in the next section).
A type of niches that seems to be mostly-preferred today is the "gaming" niches, as it's something most people can relate to.

Once you have a few niches in your mind that you want to use, it's time to start researching in-depth which one that is most likely to perform well for you.
We will be using the Google Keyword Tool to research further into this.
First off you'd like to enter your niche idea, into the "words or expressions" textarea like this:
Picture 1 above
Once you've clicked search, the tool will automatically calculate the global monthly searches, and local monthly searches, like this.

These will be very useful statistics for you, as it will be way harder to perform well on a niche, with a higher amount rather than a low amount, due to competition.
Then what you want to research is, looking around on different video sites like these:
And also be Googling your keyword to look out for how many people who seem to be using your selected niche.
As said, the less competition -> better conversion for you.
If you're just starting out
I really recommend you taking a niche with around 3,000 - 10,000 global monthly searches, it won't profit well in the start as your new obviously, but once you
get to learn, the basics of it and get into the rhythm of working with niches, websites and SEO it will be easier for you, to take it further and choose niche keywords
that have more competition.
Once you've found a niche that you've researched, that seems like one that would work out. Proceed with it, and keep trying out different ones, to see what performs well for you.
