Simo Ahava updates the GTM server-side SSL guide following the Google Cloud Platform change

Written by Paid Media Collective
IN BRIEF

Simo Ahava has revised his guide on mapping an IPv6 frontend to a server-side Google Tag Manager load balancer on Google Cloud, following a platform change that now requires a Certificate Map for configuring SSL on multi-frontend load balancers. The updated steps involve configuration steps that cannot be completed entirely within the Google Cloud Platform UI, requiring some manual intervention until Google integrates the flow.

What changed

The guide is relevant to practitioners using a GCP load balancer in front of their sGTM backend with hybrid client-side and server-side collection: particularly for maximising match quality on Meta Pixel and CAPI setups.

THE COLLECTIVE PERSPECTIVE

Why it matters for advertisers

For you, this means revisiting your sGTM SSL configuration if you are using a GCP load balancer and have recently encountered certificate errors: the steps in the previous version of this guide are no longer valid.
