Website page speed optimization was one of the essential benefits that marketers and web developers saw when the first version of Google Tag Manager was released. It was supposed to happen because tracking scripts would no longer be hardcoded but would be added through Google Tag Manager. So, does the GTM web container speed up your site? This article will showcase how moving to the GTM server from Google Tag Manager Web Container can speed up your website. Please note that you won’t see any pagespeed improvements if you’ll combine server and browser tracking. For example, your site’s pagespeed won’t increase if you use both Facebook pixel and Conversion API. In this case, FB pixel will still work in user’s browsers and slow your site.
