Many people new to internet marketing struggle to think of a niche to exploit or don't know
how to go about discovering niches. A niche is simply a 'topic' or a 'category' for example
SEO is a niche, weight loss is a niche, technology is a niche. Now those are all fairly
wide niches with lots of competition so what you need to do is either find a niche
within a niche (i.e. SEO for small businesses or weight loss with a paleo diet) that's
not so widely exploited or explore new niches which are just coming to fruition
and get in before everyone else does.
