# Attribution windows

> Set how far back TrackRev looks from a sale when assigning credit — match it to your buying cycle.

The **attribution window** is how far back in time TrackRev looks from a sale when deciding which
clicks earned it. A click older than the window doesn't receive credit. It works hand-in-hand
with your [attribution model](/revenue-attribution/attribution-models): the window filters which
clicks are eligible, the model divides the credit among them.

## Set the window

<Steps>
  <Step title="Open Attribution settings">
    Go to **Insights → Attribution** (`/attribution`).
  </Step>

  <Step title="Enter a number of days">
    Set **Attribution window** to any value from **1 to 365** days, then click **Save**. The
    default is **30 days**.
  </Step>
</Steps>

## Choosing a window

Match the window to how long people take to decide on your product:

| Buying motion              | Suggested window  |
| -------------------------- | ----------------- |
| Impulse / low-price        | 7 days            |
| Typical SaaS trial-to-paid | 30 days (default) |
| Considered / higher-ACV    | 60 days           |
| Long enterprise cycles     | 90+ days          |

<Tip>
  A longer window credits more of the early touches that started a journey; a shorter window
  credits the final push. If you run first-touch or linear attribution, a longer window matters
  more, because it decides how much of the top-of-funnel is even in scope.
</Tip>

<Note>
  Your visitor cookie lifetime is generous (one year) so the window — not the cookie — is what
  bounds attribution. Changing the window, like changing the model, applies to **new** orders.
