Adding Google Analytics to all HTML Files - google-analytics

Question

I'm trying to add Google Analytics to hundreds of pages of HTML. Theres no CMS as of yet, just static HTML pages.
I noticed all pages had:
<script type='text/javascript' src='http://www.easy.com/wp-includes/js/jquery/jquery.js'></script>
Can I just add my Google Analytics code in there?
<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','https://www.google-analytics.com/analytics.js','ga');
ga('create', 'UA-XXXXXXX-1', 'auto');
ga('send', 'pageview');
</script>
Or does it have to be in a file with a specific name like analytics.js?

Answer 1

Adding GA to the page requires the HIGHLY recommended code snippet:
<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','https://www.google-analytics.com/analytics.js','ga');
</script>
so that you'll always have the latest library. If you host the analytics.js library yourself, you may not get any updates pushed out to you. The snippet can also be hosted in a file that gets included on every page of your site as well.
