How-To: Create a report that compares two date ranges

Overview

The Compare Date Ranges feature in Explorer allows you to evaluate performance over time by directly comparing two time periods side by side. Whether you're measuring week-over-week results or year-over-year growth, this feature helps surface meaningful trends quickly — across both charts and tables.

Use it to answer questions like:

  • How did impressions change from last week to this week?

  • What’s our click-through rate compared to the same time last year?

  • Are we pacing ahead or behind recent periods?

You can also use Ask Alli to compare performance across time periods. Just ask something like:

“Show me impressions by channel for the last 30 days compared to the previous 30 days.”

Ask Alli will generate the chart and table instantly — no manual setup required.
