Entry Views keeps track of the number of views a post/page (or any post type) has. It comes handy with a widget for showing the most viewed posts, a shortcode for displaying a post’s view count, and handy template tags for use within theme template files.
The plugin was originally created as a script for use with some of my themes. However, it’s not a good idea to package something like this with a theme because it’d stop working when switching between themes. Therefore, the script was ported over into a plugin for everyone to use, regardless of the theme they’re using.
