Order By Engagement allows developers to track post engagement and sort by those tracked values.
Order By Engagement is a WordPress plugin designed to allow theme developers to order posts by a value which corresponds to how engaged with a post users appear to be.
At the moment, OBE tracks engagement only be increasing a value, stored as a custom field value, when a corresponding post is accessed. Plugin settings allow administrators to throttle the increase of that value and to erode the current value over time. This is how the plugin tracks the maximum engagement value for a post and contrasts it with the current engagement value.
