“Post Hit Counter” does what it says on the tin – it counts how many hits your posts receive. Hit counts are displayed in a new column in the post list table, in the submit box on the post edit screen and in the admin bar on the frontend.
Plugin Features
<ul>
<li>Easily visible hit counts in the dashboard and in the admin bar on the frontend</li>
<li>Shortcode to display view count for current or specified post</li>
<li>Widget to display your most viewed posts anywhere on your site</li>
<li>Dashboard widget to show your most viewed posts at a glance</li>
<li>No complicated analytics and statistics to wade through</li>
<li>Option to select which post types must be counted</li>
<li>Option to select which user roles should not trigger the hit counter</li>
</ul>
This is not meant as a replacement for more advanced analytics plugins – it is a counter so you can see which of your posts are more popular without diving too deeply into complicated viewing statistics.

This plugin was initially created as a demo for <a href="http://2014.capetown.wordcamp.org/session/building-your-first-wordpress-plugin/" rel="nofollow ugc">a workshop</a> I ran at WordCamp Cape Town 2014. I have since fleshed it out and enhanced it to be more useful.
