Enabling GCLID for attribution marketing

GCLID (Google Click ID) is a unique identifier added to URLs when Google Ads’ autotagging is enabled. Unlike UTM parameters, this numeric string doesn’t provide human-readable campaign data — it’s designed for Google’s internal attribution models. While Madlitics doesn’t include GCLID in default fields, you can easily enable tracking for specialized use cases.
How to capture GCLID as a Madlitics field
Capturing GCLID data through Madlitics follows the same process you used when setting up your initial channel and segment fields. The configuration process varies slightly depending on your form platform of choice. If you need a refresher on setting up channel and segment fields, you can find detailed instructions in our [previous guide on form configuration].
GCLID:
Field label: gclid
Default value: [gclid]

Once enabled, GCLID data will flow into Madlitics reports alongside your attribution data.
GCLID tracking becomes relevant in specific scenarios — like troubleshooting discrepancies between Google Ads and Madlitics, meeting compliance mandates for click ID retention, or syncing data with custom tools requiring Google’s native identifiers. While most teams will never need it, we’ve made it simple to enable because Madlitics thrives on adaptability. Your success depends on having every tool you might need, even if you rarely use it—and we’re here to ensure you’re always prepared.
