Plug the communication leaks. Focus and focus some more
Develop a database of clients and potential clients. Divide them into categories based on elements such as geography, sex, language and service they are likely to require. Keep this database up to date and segment it as much as possible with any additional information you can gather. Utilise this information in developing your marketing approach. This enables a focus that ensures you are providing the right message to the right target audience.
