Last click

Last click is the attribution model that gives all the credit for a sale to the last known touchpoint before the purchase. It is the default model of most measurement tools, because it is the easiest to explain.

What it is for

It judges what closes. A follow-up email, a retargeting ad, a link in bio clicked on the day of purchase: those are the end-of-journey levers, and no other model gives them their real weight. It is also the most readable model in a meeting, because a sale has a single owner.

How it is calculated

You keep the last touchpoint before the conversion and attribute the whole amount to it. Before matters: a click after the sale cannot have caused it, and keeping it would reverse cause and effect.

The classic mistake

Taking it for the truth because it is the default setting. A default model is not a neutral model: this one mechanically favours everything that happens close to the purchase, and makes everything that prepared it disappear.

On last click, three touchpoints out of four get zero. They still happened.

What Subtraq does with it

Subtraq offers it as a reading of the recorded touchpoints, alongside first click and linear. Switching from one model to another rewrites no data: the same touchpoints are simply split differently.

An attribution model is not understood by reading it: it is understood by watching two campaigns swap places when you change it. The demo opens a workspace filled with fictional data, labelled as such, where the three models are compared on the same sales.
