Does this overwrite existing campaign tracking templates?

Yes. It sets the tracking template at campaign level, so test first if some campaigns already use custom setups.

Why use a custom parameter for campaign name?

It keeps the template cleaner and makes campaign names easier to pass consistently without hardcoding them into the template string.

Can this be restricted to selected child accounts?

Yes. You can replace the simple withLimit pattern with withIds if you want explicit account control.

Does this support video campaigns too?

The example leaves video commented out by default, matching the original intent. You can enable it if that fits your account setup.

About This Script

MCC UTM Tracking Template Updater is designed for agencies and in-house teams managing multiple Google Ads accounts from a single manager account. It applies a common tracking template and custom parameter pattern across campaign types so reporting stays consistent.

This updated version keeps the original intent but uses cleaner helper structure, safer logging, and current campaign iteration patterns. It also uses a capped account selector so the execution scope remains controlled.

Because tracking changes can affect reporting and landing-page behaviour, it is best used in a staged rollout. Start with a small account subset, validate URLs, and only then widen execution.

Implementation Notes

Replace or adapt the TRACKING_TEMPLATE if your reporting team uses a different UTM convention.
Set ACCOUNT_LIMIT to the number of child accounts you want to process in one run.
Optionally add specific account IDs instead of relying on a simple limit.
Run on a small test batch first and validate final URLs in the Google Ads UI.
Schedule only after confirming your analytics platform parses the UTMs correctly.
