Topic summary

A user’s Google conversion tracking suddenly stopped working for both organic and ad conversions, despite no changes being made to their Gtag setup over the past 12 months.

Root Cause:

  • Shopify recently made platform changes that broke existing tracking scripts
  • Google sent out notifications requiring users to update their tracking implementation

Current Status:

  • Google Shopping conversions through the app still function normally
  • Only manual tracking implementations are affected

Recommended Solution:

  • Contact Google support directly through their Shopify third-party support channel for assistance with updating the tracking code

I’ve made no changes to my Gtag or anything like that. However, for some reason, my conversion tracking is no longer working. This is for both organic and ad conversions. Any advice on a fix for this?

Google Shopping still tracks ads through the app.

How would the code that’s been working for the past 12 months suddenly be incorrect?

Just a week or two ago, Google announced you need to update the tracking. You should have received an email. That is because Shopify made changes where additional script no longer work.
