I am trying to enable Google Analytics to my web application.
Do I need to add the "JavaScript tracking snippet" like below in my every html pages within my web application ?
Or would it be enough to add this snippet only in the landing page please ?
<!-- Google analytics code starts -->
<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-12345678-1', 'myweb.com');
    ga('send', 'pageview');
</script>
<!-- Google analytics code ends -->
