A membership site is a private website for customers who usually pay a monthly fee. By building a membership site, you can bring in a steady stream of income, since members recurrently pay you for accessing your site. In return, your job will be to provide exclusive content for your customers, which will account for more user interaction and feedback through forums and comment sections.
People who invest in your site are most likely to invest in the products and services your site is selling. As long as there is a demand for services or products, you can always attract more customers. To encourage non-members, you could offer a free trail subscription that expires unless the member renews and pays.
