Last-click attribution rewards the wrong work

In short Last-click attribution is outdated, and campaigns should be optimized to outcomes rather than clicks, which no longer capture the whole story.

By Jeff Greenfield · May 13, 2026

Counting clicks in an AI-first world? You're rewarding the wrong work—time to rethink attribution.

Clicks don't tell the whole story anymore.
I've seen campaigns tank because they chased the wrong metrics.

Time to wake up… last-click attribution is a relic.

Optimize to outcomes, not clicks.

If you miss this, your competition won't.

Rethink your metrics. Embrace the shift. Thrive.
