Measurement
Click ID
An identifying code an ad platform adds to the landing page link when someone clicks an ad, such as Google's gclid, Meta's fbclid or Microsoft's msclkid.
What it is
The code identifies that click, so a later lead or sale can be matched back to it.
Why it matters
For lead generation and e-commerceIt is the link between an ad and an offline result, such as a qualified lead or a signed deal.
In practice
Capture it on the landing page, store it with the lead or order, and send it back with offline conversion imports.
A common mistake
Dropping it in a redirect or a form that does not save it, which breaks the link for every lead after.
