First of all I assume you know why you are interested in Google Analytics Service.
Usage Guide:
The analytics.js library is a JavaScript library for measuring how users interact with your website. This document explains how to add analytics.js to your site.
Now put the following js code snippet in the <head> section of your pages.
In Rails; keep this snipped in your `layouts/application.html.erb`
<!-- Google Analytics --> (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-XXXXX-Y', 'auto'); ga('send', 'pageview'); <!-- End Google Analytics -->
The above code does four main things:
- Creates a
element that starts asynchronously downloading the analytics.js JavaScript library fromhttps://www.google-analytics.com/analytics.js - Initializes a global
gafunction (called thega()command queue) that allows you to schedule commands to be run once the analytics.js library is loaded and ready to go. - Adds a command to the
ga()command queue to create a new tracker object for the property specified via the'UA-XXXXX-Y'parameter. - Adds another command to the
ga()command queue to send a pageview to Google Analytics for the current page.
For modern browsers
This will use the feature of modern browsers to preload the assets
window.ga=window.ga||function(){(ga.q=ga.q||[]).push(arguments)};ga.l=+new Date; ga('create', 'UA-XXXXX-Y', 'auto'); ga('send', 'pageview'); async src='https://www.google-analytics.com/analytics.js'> <!-- End Google Analytics -->
