Your market is the customers for your product or service. Before you can research you will need to determine who are the customers for your business idea. Here are a few questions to get you started:
If you have an idea, you have already thought of at least one customer, but think about those groups more broadly and narrowly. For example, if you have identified dog owners as your target market a broader group would be pet owners and a narrower group would be owners of a particular breed.
Search for articles about your competitors in a database or in a market research report to see who they identify as their target markets.
Once you have identified a particular group, think about who might be related targets. For example, if you have identified millennials as one of your target markets, how about Gen Y or Gen X as additional markets?
It is always best to brainstorm many possible target markets before you start searching for data. This will help you avoid needing to start your searches again.
Once you have identified your target markets, you can use secondary research to determine the size of the segment and whether it's growing, shrinking or stable. Market Research Reports do a good job of outlining the macro trends of these target markets.
