What is Attribution?

Attribution is deciding which marketing touchpoints get credit for a conversion.

How does attribution work?

You log the events a customer touched before buying, then assign each one a share of the credit. Last click gives everything to the final touch. First click gives everything to the discovery moment. Multi-touch splits credit across the path. Algorithmic models use statistics to estimate what each touch actually contributed.

Why does attribution matter?

It decides where your next dollar goes. Choose last click and you will overfund search while starving the awareness channels that fed it. Attribution is what turns the acquisition stage of pirate metrics from a guess into a budget.

Where did attribution come from?

The idea borrows from attribution theory in psychology, which studies how people assign causes to outcomes. Marketing adopted it as spend moved from offline ads to digital, where every touch could finally be logged, as Wikipedia traces it. Affiliate marketing made it urgent, since attribution is how affiliates get paid.

How do you use attribution well?

Pick a model, then hold it steady long enough to compare periods honestly. Treat the output as directional, not exact. Run holdout tests when a channel's credit looks too good. And remember that no model sees the podcast, the group chat, or the friend who vouched for you.

Bottom line: Attribution is a useful fiction, and the model you pick decides which channel looks like the winner.
