This is the real key to successful newsgroup marketing. There are many people in the newsgroups that they are shouting their wares on every newsgroup on the Internet. These people are wasting time and bandwidth. When you are giving real advice or solid information, this will build your reputation as one who knows their subject. Repetition of these activities in newsgroups will build awareness, a presence for you that will bring more interested clients to your virtual doorstep, whether it is a web site, an email or an auto-responder address.
Repetition is key to building a presence in newsgroups or any medium at large.
This is a very effective way to get your message out there by becoming a regular participant in these newsgroups. You have to be there every day and helpful. Remember Give before Receiving. Having your own domain name is like having your own virtual real estate. This will help you to create name recognition.
