Click IDs Are The Key

When someone clicks an ad, the platform appends a unique click identifier to the landing page URL. That id is the thread that lets you reconnect a future outcome to the exact click and campaign.

The main click IDs

  • Google Ads: gclid (and gbraid / wbraid for iOS app and web).
  • Microsoft Advertising: msclkid.
  • Meta: fbclid.

Capturing this value on arrival is the foundation of the whole approach. Without it, an offline sale cannot be matched to the click that produced it.

Key takeaway

The click id (gclid, msclkid, fbclid) is the link between a click and a later outcome. Everything else depends on capturing it.
