What is Page Tracking
Page tracking allows measurement of the number of views for a particular page on the website.
Where to place the code
The code should be added before the closing </head> tag,
<script>
(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,'script','//www.google-analytics.com/analytics.js','ga');ga('create', 'UA-21090649-1', 'auto', 'inforMEAExternTracker' );
ga('send', 'pageview', location.pathname);</script>
