step by step

how we work

step 1

chaos

Tracking has become extremely complex; Google updates, Apple tracking preventions, and so much more. Your client's tracking is sending data, but that's about it. When tracking doesn't work for a few days, nobody notices.

Event parameters for Google Ads conversions are here.

What does this mean for your GTM tracking setup?

---

1. Enhanced Conversions can now be set up in the Google Ads Conversion Tracking tag again.

↳ Add the "user_data" parameter (just like in GA4) using a User-Provided Data variable.


2. Use event parameters to populate custom variables in Google Ads for better reporting.

↳ Custom columns are not available at the product level in Google Ads. Use custom variables instead.

↳ Example: I use the "profit" parameter to populate a custom variable that shows the order profit per product ID in Google Ads.


3. Setting up event parameters is not (yet) supported in the sGTM version of this tag.

↳ Make sure to include event parameters in the requests you send to sGTM. The tag will then include the parameters automatically.

↳ If the data you want to send to Google Ads is only available in sGTM, use transformations to ensure the parameter contains the correct data.

---

This addition was long overdue, but now that it's finally here, it will make it much easier for marketers to enrich their Google Ads reporting.

No more GCLID in Safari from September onwards.

Using the iOS 26 beta, these are my findings:

---

→ Root cause: Settings app > Safari > Advanced > Advanced Tracking and Fingerprinting Protection.

↳ By default this is set to "All browsing", which results in removing the GCLID.

↳ GCLID is not removed when this setting is set to "Private browsing" or "Disabled".

↳ Both GBRAID and WBRAID tracking parameters are NOT removed.

---

I feel like almost everyone is going to be using the default "All browsing" option here, without touching the settings.

So all these users on iOS 26 are going to be attributed solely via GBRAID / WBRAID.

If you don't want this, you can restore the GCLID for Google Ads attribution via the GTM web container.

Here's a guide:

---

1. Add a parameter (e.g. "lnid") containing the GCLID value to your URLs.

↳ Set your URL suffix on account-level to "lnid={gclid}".


2. Restore the _gcl_aw cookie based on this parameter.

↳ Use my tag template (link to container import file in comments) to capture this parameter and create the cookie.

---

Unfortunately this only works for Google Ads.

With Meta and other ad platforms you're not able to append click IDs via custom URL parameters.
