How To Build Credibility Online
Putting up a web site is an accomplishment, but it is not enough. You've got to give people a reason to care that you have a site. Online and off, people like to do business with people they know and trust. Online, a great way to build relationships and credibility is to get involved in the cyber-community. But no one will listen to you if all you do is try to sell them your wares. In fact, they'll be gone faster than you can say "click!"

Using E-Mail
Unsolicited bulk e-mail (known unaffectionately as spam) is the junk mail of the Internet. Spam almost derailed the Internet's promise of allowing the gathering of information permitting firms to get closer to their customers. Most reputable businesses have edged away from spam and moved into e-mail by request.

Newsgroups, Mailing Lists & Forums
Mailing lists, newsgroups and forums are online places where people meet, exchange information, discuss topics and disseminate knowledge. Participating in newsgroups, mailing lists and forums lets you promote your web site by communicating directly with many thousands of people worldwide who are the most likely to be interested in your product or service. You also gain credibility and visibility, and the cost is nothing but your time. But you must follow the unwritten rules.
