Dan Wilkerson

This article is a collaboration between Simo and Dan Wilkerson. Dan’s one of the smartest analytics developers out there, and he’s already contributed a great #GTMTips guest post. It’s great to have him back here sharing his insight on working with Accelerated Mobile Pages (AMP).

So, we’re back on AMP! Simo wrote a long, sprawling AMP for Google Tag Manager guide a while ago, and Dan has also contributed to the space with his guide for AMP and Google Analytics. Both of these guides touched upon a subject that might be one of the reasons to stay away from AMP for now: Client ID matching across AMP, your regular website, and any caches or CDNs that serve the AMP version.

This article is a guest article by someone from the analytics community I really look up to. Dan Wilkerson is an analytics developer at Bounteous, a company I hold in high esteem. Dan is one of the smartest technical analytics experts out there, and a large bulk of the awesome scripts and hacks that Bounteous produces (almost on a daily basis) have been orchestrated by him. So I’m very pleased to give the floor to Dan, so that he can tell you all about using the pesky document.write() method in your Google Tag Manager Custom HTML Tags!
