Personal sGTM and Google Tag Gateway for Advertisers Shenanigans

October 7, 2025 by Jose Uzcategui Leave a Comment

Preface: this post is just a personal note, not an implementation guide.

I’ve been ringing the bell for Google Gateway for Advertisers for some time, excited about the possibility to address the ITP issue in iOS without much technical investment. That was until I was corrected by our tech team that, even though cookies are set 1st party with Google Tag Gateway, ITP recognizes when the cookie is set by the script and not by the serv… anyway, it does not do what I thought it would do.

I had implemented Google Tag Gateway on this blog post for some months and then, I had enough. After learning the only way for battling this ITP shenanigans was server side, I deployed a basic server side implementation on this blog.

The first thing that comes to mind is, will this cost any money? I don’t have much traffic here, so hopefully I don’t incur any costs.

So, after all these trials and errors, I am double tracking to two different GA4 properties – one client and one server-side. I’m also using Google Tag Gateway. Let’s see how that goes.
