Ever heard of the Pareto principle? you know, the one that says 20% of customers make up 80% of sales?
Well, this is true for many businesses over many different sectors and could well be applicable to your business. Have a look and see if this works for your business and if it does then find out what these customers have in common and why it is they use your services or buy your product. From here you should be able to profile your ideal customers and see which potential new customers you should be targeting.
