Saves view counts from <a href="https://wordpress.org/extend/plugins/jetpack/" rel="ugc">Jetpack</a> Site Stats module as post meta data. This can be useful for displaying view counts in your theme and building <a href="https://codex.wordpress.org/Class_Reference/WP_Query#Order_.26_Orderby_Parameters" rel="nofollow ugc">custom queries</a>.
What makes this a better solution over other view-tracking plugins is that it simply pulls the information from Jetpack, which is popular and provides fairly accurate data, so this has very little overhead. It’s a streamlined plugin that piggybacks off another which you might already be using.
Comes with a shortcode to display views and a filter to change the post meta key where views are saved.
Thank you to <a href="https://profiles.wordpress.org/dimadin/" rel="nofollow ugc">Milan Dinić</a> for improvements in the code after the initial release (and for the Serbian translation)!
