In the past few years, we have covered a whole host of plugins that let you sell your premium content. The Jeg Paywall PayPal plugin is also worth a look. It is a WooCommerce extension that adds a paywall system to your website, so you can monetize your content like a pro.
The Jeg Paywall plugin restricts access to your premium content but shows a summary to encourage your visitors to pay. It supports recurring and flexible payment plans. Your visitors will have the option to buy a single article or subscribe to access all your premium content.
