At this point, you should have a good idea what niche you will like to build your business around as your ideas and your target audience’s needs and wants coalesce.

This is where you zone down on tools like google trend to see if the niche idea is trending well; google keyword planner, Jaaxy or other keyword tools to determine search volumes and competition.
