After tackling Google Analytics a couple of weeks ago, we couldn’t leave it there. Not when there’s one other tool that’s essential if you want accurate data. Yup. We’re talking about Google Tag Manager or GTM – the grand tourer of the Google tool kit. (Sorry. Could not resist.) What makes GTM indispensable? It’s designed to help marketers set up tools, tracking and plugins, without involving developers in the process. You can use it to track the metrics you want and to add code to your site even if you can’t code.
