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>.

GA Analytics

A handy way to insert full Google Analytics tracking code on all pages.

CAOS can be downloaded for free without any paid subscription from <a href="https://wordpress.org/plugins/host-analyticsjs-local/" rel="ugc">the official WordPress repository</a>.
CAOS (Complete Analytics Optimization Suite) for Google Analytics allows you to host gtag.js locally and keep it updated using WordPress’ built-in Cron-schedule. Fully automatic!
Not a big Google Analytics user and just curious about your pageviews? CAOS fully supports <a href="https://github.com/jahilldev/minimal-analytics/tree/main/packages/ga4#readme" rel="nofollow ugc">Minimal Analytics 4</a>. An extremely lightweight alternative to Google Analytics’ default libraries (gtag.js). Minimal Analytics also helps you get rid of that annoying Unused JS notice in Google PageSpeed Insights!
Whenever you run an analysis of your website on Google Pagespeed Insights, Pingdom or GTMetrix, it’ll tell you to leverage browser cache when you’re using Google Analytics. Because Google has set the cache expiry time to 2 hours. This plugin will get you a higher score on Pagespeed and Pingdom and make your website load faster, because the user’s browser doesn’t have to make a roundtrip to download the file from Google’s external server.
Just install the plugin, enter your Measurement ID and the plugin adds the necessary Tracking Code for Google Analytics 4 to the header (or footer) of your theme, downloads and saves the gtag.js-file 
to your website’s server and keeps it updated (automagically) using a scheduled script in wp_cron(). Or if you’d like to use the locally hosted file with another plugin, check Compatibility Mode under Advanced Settings, Either way, CAOS is a set and forget plugin.
