Discover 3 different ways to install Google Tag Manager on your WordPress website. After making my previous video below, I decided to show people how to install Google Tag Manager using a header and post injections plugin, how to install Google Tag Manager using the Duracelltomi Google Tag Manager for WordPress plugin, and how to do a manual install so you can place the code directly in your theme editor file. Google Tag Manager is useful for managing all of your different tags including Google Analytics, the Facebook Pixel, Microsoft Advertising, and more.
