Incrementality

The uplift that would not exist without the ads

What it is

The uplift that would not exist without the ads

The difference between what happened with advertising and what would have happened without it. Attribution credits a source with everything that passed through it; incrementality asks how much of that would have come anyway. Tested by switching a channel off in some geos or for part of the audience.

Example

What it looks like in numbers

Retargeting showed 1,200 deposits a month by attribution. Switched off in two of six countries: deposits there dropped by 140, not by the 400 expected from its share. The incremental contribution was a third of what was credited.
