What is Google Tag Manager (GTM) and How To Install It and Link It To Google Analytics [2022]

Have you  ever tried to install different types of scripts and tracking codes on your website which affects the performance and makes it harder to debug?

Google Tag Manager is a free cool tool that enables marketers to extract digital marketing data by using code snippets on your website. This is where you can add only 1 Javascript code to your website, then you can manage all your additional tracking codes, conversions tracking, Facebook Pixel….

The cool thing about GTM is that it loads all these scripts asynchronously, which means it does not block other elements from rendering on the page. so a slow loading script won’t block other tracking scripts or tags.
