Last Viewed Posts by WPBeginner is a WordPress plugin designed to enhance user engagement by displaying a personalized list of posts and pages that visitors have viewed on a website. This functionality is achieved through a widget or a template tag, which can be easily integrated into your WordPress site. The plugin is lightweight, as it saves the list of viewed posts in each visitor's web browser without storing any data in the site's database, ensuring that website performance remains unaffected even with high traffic.

This plugin is particularly beneficial for websites looking to improve user retention and navigation. It does not require any backend storage, making it efficient and straightforward to implement. However, if JavaScript is disabled or no posts have been viewed, the plugin will not display any content. Overall, Last Viewed Posts is a practical tool for WordPress users aiming to personalize the browsing experience for their visitors.
