Write down your target customer characteristics and build a target customer profile on which you can focus your marketing efforts.
Creating a profile and committing it to words on paper helps you think carefully about who your ideal customer is, how they behave and what they are looking for in a product or service.
Don't waste your energy and money marketing to anyone other than your perfect customer - they are the ones who want and need your products and services.
Your target customer profile helps you share information with your staff, partners, contractors - anyone who will be working for you to reach the best customers you want for your business.
Don't market on a hunch, a guess or a feeling. Get hard scientific information for your choices and record it on a Target Customer Profile.
