Your products and services are designed to solve a particular issue, whether that is keeping your clients technology running (IT support, perhaps), helping them communicate effectively (video production, maybe) or having a more comfortable day at the office (selling great office chairs). For each product or service, there is a target audience and an Ideal Client.
Defining your Ideal Client(s) helps you to determine your target audience and focus your marketing to make it more effective and generate more leads.
