My new home is I believe we can gain large audiences for cheap or free!
A niche market is a sub division of a market that is specific and detailed.
Sometimes these niche markets are a little weird or on the fringe. When we uncover these niches doing things like keyword research, we say that we are drilling down into a niche.
I hope this helps to clear up some misconceptions you may have. Find your niche and don’t be afraid to be bold or controversial!
