# Attribution Windows

> Attribution windows determine the time period considered for associating a conversion with a click, campaign, or marketing channel.

In other words: The window defines **until when** an interaction can receive credit for a sale.

## Why is this important?

Attribution windows help answer questions like:

* What is the average time between the first click and conversion?
* Does an awareness campaign still influence conversions weeks later?
* How to compare short-term vs. long-term results?

The choice of window can change the interpretation of results. A short window gives credit only to recent interactions, while a longer window shows the impact of top-of-funnel channels that act earlier in the journey.

***

## Available windows in Nemu:

#### Full Journey (Infinite Window)

Considers all interactions from when the Nemu Pixel was installed to the present moment.\
This is the broadest view of the journey, ideal for evaluating the **total value of each channel** over time.

#### 7 days

Considers only interactions that occurred up to 7 days before conversion.\
This is a shorter window, useful for understanding quick-response channels, such as remarketing or one-time promotions.

#### 30 days

Considers interactions up to 30 days before conversion.\
This is the most common market standard and provides a balanced view between acquisition and conversion campaigns.

#### 60 days

Considers interactions up to 60 days before conversion.\
This is useful for **longer purchase cycles**, where the customer researches, evaluates, and only later returns to buy.

## Where to find the attribution window in Nemu?

You can adjust and view the attribution window in two places on the platform:

1. **Campaigns Tab**

   * In campaign tables, each metric is presented according to the selected window.
   * This allows you to compare, for example, the performance of a campaign in 7 days vs. 30 days.

2. **Analytics Tab**
   * At the top of the table, there's an **attribution windows** filter.
   * Simply select the desired window to update all displayed data.

***

## Summary

* **Full Journey** → infinite view, from the beginning to today.
* **7 days** → ideal for quick response campaigns.
* **30 days** → balanced view and most used in the market.
* **60 days** → recommended for longer purchase cycles.

In Nemu, you have the flexibility to switch between these windows and better understand the role of each channel in different time horizons.
