Would you like to learn how to boost your WordPress site speed by locally hosting gtag.js (otherwise known as Google tag)? You have come to the right place! Read on.

Sometimes in May 2021, Google’s Page Experience updates for mobile search rolled out Core Web Vitals as one of the important ranking factors to always observe by website owners to constantly appear on search results.

What does this mean for every business owner and stakeholder using a WordPress website? It means that: for your products and services to continually grab the best spots in search results, your site must ensure it always passes the Core Web Vitals Score tests.

Oh yeah… Google, being the king of all search engines is always particularly concerned about achieving a healthy web ecosystem.

While the Core Web Vitals are important for delivering a great user experience, there are other vital actions to take as well. One of which is by hosting the global site tag JavaScript (gtag.js) locally on your website’s server which aids in faster script loading.

In this article, we shall be discussing what Gtag.js is, how to implement it on your WordPress site or blog the right way to boost or improve speed performance, and lastly how to host it locally using a reputable WordPress tool.

What is gtag.js (or Google tag)?

It will do website newbies a favour first if they understand what gtag.js is. The gtag.js (Global Site Tag or Google Tag) is a JavaScript framework that is used to add Google tags directly to web pages.

The script usually comes with most Google products such as Google Adsense, Search Console, Pagespeed Insights, and others connected to sites for tracking and measurement purposes.

For example, the Google Analytics software comes with gtag.js which sends event data such as website traffic and other useful information about your website visitors. That’s how GA collects and displays data for your website.

How Does Gtag.js Affect Site Performance?

Normally, whenever the gtag script is manually added to your site, the snippet takes time in loading anytime a visitor lands on your site. The time it takes to load is recorded in one of the Core Web Vitals thresholds called LCP.

When this time exceeds the normal loading time, it provides a bad user experience which results in poor site performance. The preferred loading time should be 2.5s or lesser. Anything above that records poor performance just like is indicated in the image below.
