Hidden or restricted content is any valuable media or material on your website that is kept hidden from people until you grant them access. Access is usually granted in exchange for performing a desirable action on your website, such as an email opt-in or purchasing a product.
Content restriction often goes hand-in-hand with membership websites because they provide a quick way to improve the value proposition of the membership by making special content available after it’s purchased.
This is not the only use, however. Websites can take advantage of content restriction for other purposes like granting employees access to internal tools and scheduling content in advance.
