Membership sites are online platforms where users pay a fee to access exclusive content, services, or community features. These sites often offer resources like articles, videos, courses, or forums that are not available to the general public. The subscription model can vary, with options for monthly, yearly, or one-time payments. Members typically enjoy benefits such as personalized support, networking opportunities, and specialized content tailored to their interests. Popular examples of membership sites include Patreon, where creators share exclusive content with supporters, and MasterClass, which offers online classes from industry experts.
