This installment of WordPress Developer Tips offers a simple, code-based method for tracking and displaying popular posts. Staff author Morten Rand-Hendriksen will help you build a custom plugin to track the popularity of posts, based on views, and then create a widget to display a list of the five most popular posts on the front page, or on any other widgetized area, of your WordPress site. This feature will help visitors discover more content on your site, and help site owners understand what posts are trending.
