Promoting a membership website is done exactly the way any website is promoted. When you build any website the only person that is aware that it exists on the Internet is you. So, it is up to you to promote and advertise your site and let the rest of the world know where to find you.
You accomplish that task while you are building your own credibility. One will not exist without the other. A membership website builds credibility and credibility builds a membership website. As more people join the site you have created and receive valuable information and personal attention, they will tell others. This provides social proof of your trustworthiness and expertise.
