The Problem :

Google analytics requires a Page URL to track analytics inside of the GA dashboard. Single Page applications only have mock transitions and are not actually changing there URL like classic webpages.

The Solution:

Using React-router , we have access to the powerful History API that uses the browser to manipulate the URL to look and function like an authentic page change.


How to make Google Analytics work in a Single Page Application (SPA)


in the header of the index.html page, load the script to load 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', '//', 'ga');


Inside app.js on componentDidMount() create an instance of GA script and attach it to the window so we have access to it at all times.

componentDidMount(){'create', 'UA-XXXXXXX-X', 'auto');



create a method that takes in a url and sets the page view , then sends the view to google analytics:

setPageAndSendToGA = url => {'set', 'page', url);'send', 'pageview');

Next, Create a method that takes in the location provided by this.props.location.

Build a conditional that fires our setPageAndSendToGA() whenever a specific URI path is passed in.


  trackGoogleAnalytics = location => {
    if ( {
      if (location.pathname == '/sign-up') {
        let url = location.pathname;

      if ( == 10) {

        // here we are using search Params, so we concat it to the url string

        let url = location.pathname +;



Then in the render() we call the function, and it will fire every time the page location changes




Checkout the article listed above in the sources, for a more detailed explanation, this is just my adapted implementation I used for our app.


  • there is probably a better time to run this function , instead of the render. for our use case, this render is in the top most component in app.js

  • there might be a better way to listen for page changes in browserRouter object , instead of using the props.location

  • please feel free to critique me below in the comments so i can learn to! or make adjustments to the article.

How does implementing Google Analytics this way impact your application if Google's script fails to load?

Nice observation !

I actually didn’t even plan for google to fail at anything hahahahaha

But , luckily this method will be unphased by google analytics failing because what it’s doing is checking to see if the ga function is loaded in the first place .

If you look at trackgoogleanalytics() you can see that the first conditional checks if the method is attached to the window object , if not then none of the code runs
