# Choose an attribution model for the decision

> Match the model to the question you're answering

**Best for:** deciding which model to read before a budget or creative decision.

## Before you start

There is no single correct model — each answers a different question. Know what you're deciding before you pick.

## The steps

<Steps>
  <Step title="Understand the two families">
    Simple models give all credit to one touchpoint; multi-touch models divide it.

  </Step>

  <Step title="Compare models on your own data">
    Run the Model Comparison tool to see every model side by side.

  </Step>

  <Step title="Set the window to match the decision">
    Short windows for fast feedback, long windows for considered purchases.

  </Step>

  <Step title="Walk one order through the models">
    See exactly how credit allocation changes what each model reports.

  </Step>

## What to expect

Comparing against an ad platform? Remember most platforms report on last non-direct touch — pick the same model on both sides before drawing conclusions.
