Google Analytics tool is important to see how many users pass to your website through the google search engine and also with direct transmission from any social media platform or direct URL.

Is Google Analytics effective by website speed?

This is an important point, if you have added Google Analytics to your website, you must add some JavaScript code to your website pages.

This code must make your pages load slowly, why? the answer is:

The code that you add contains an external JavaScript file that is responsible for recording traffic on your site, that JavaScript file it's has a big file size, so it takes a long time to load.

This part is when you test your website via Google PageSpeed Insights and get pad results and you see the reason for this pad result is the JavaScript file size of the Google Analytics service.

What can I do?

Don't worry, every problem in the developing world has a way to fix.

You can fix the Google Analytics JavaScript file load time delay issue with a simple and clever trick, which is a trick that delays file download after page loads and doesn't affect your page speed anymore.

How to do that?

Ok, first you should remove the previous Google Analytics code and put the new code that will I give you now.

This code:

// Lazy Load analytics start

var myAnalytics = document.createElement('script');

window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());

  gtag('config', 'G-ZR7PZBPEX9');
// Lazy Load analytics end
