It is worth to mention that WordPress doesn’t have Google Analytics support out-of-the-box. 
To add the Google Analytics code for your WordPress website you need to relay either on the WordPress theme or plugin.
Once you installed the plugin, please navigate to the Settings section in the WordPress dashboard.
From the Settings section select Google Analytics Setup and add your tracking 
code. From now on, on all your website pages you will have the tracking code 
enabled.
Also check <a href="https://github.com/dejanbatanjac/ga-analytics" rel="nofollow ugc">GA Analytics on Github</a>. 
NOTE: It requires at least WordPress 4.5.
Here is the <a href="https://www.google.com/analytics" rel="nofollow ugc">link to Google Analytics</a>.

Analyticator

Unfortunately this plugin no longer works. The plugin settings page doesn't display properly and it also breaks the Customizer (i.e. You can't access the Customizer if the plugin is activated). It's been over 9 months since any support ticket was answered or the plugin was updated.

No longer works and no longer supported

Easily view your Google Analytics and real-time statistics inside WordPress! Makes it super simple to add your tracking code too.
