# Insight: Last Impression to Conversion

The Insights Lab provides reports that help visualize campaign performance and effectiveness. These reports can be accessed at both the **Ad Set** and **Campaign level** of the Quantcast Platform by hovering over the ad set or campaign and clicking **Insights**. In this article, we will walk through how to interpret the **Last Impression to Conversion** report.

## **Description**

The Last Impression to Conversion insight highlights the time elapsed from the last impression to conversion. This report aggregates weekly data for the Ad set or Campaign being drilled into. By visualizing the breakdown of your converting audience, this report allows you to identify variations in the customer journey. As such, it is useful in validating any idea you may have about optimal attribution and recency windows.

The report can be used to understand the lag between the change in targeting settings and changes to your conversion volume.

## **Definitions**

- **Y-Axis** = Specific time intervals
- **X-Axis** = % of total Converting audience
