Demonstrate your expertise by answering questions and offering advice, remember to include your company name and contact information in your signature. Join one of the expert sites where people can solicit answers from you, this may help build your reputation and give your business exposure. Consider advertising in an e-zine that is distributed to your target audience. Exchange links with other web sites that have exposure to your target audience. Most of the business owners I associate with state that the majority of their clients request their services because someone recommended them.
Word of mouth is a powerful client building tool.
This is why customer service is so important. If a colleague is discussing a need for services with one of your clients and your client knows that you offer such a service he can sell your service for you and this method can have a snowball effect and before you know it you may have a clients to keep your business flowing nicely. Always tell people about your business, they may be looking for someone at that time to meet their needs or they may know someone who has a need for your services. Consider offering a referral bonus as well, this gives people an incentive to drop your name when they have the opportunity. One of the most important aspects is to get your name out there.
