# Comparison Groups Report

> How to use the Comparison Groups report to build and compare custom segments of ads in Creative Insights.

The Comparison Groups report enables you to construct individual segments of ads using advanced filters and compare them against each other. Use it to build hypotheses, evaluate A/B test results, or define your next creative approach.

## Creating a Comparison Groups Report

<Steps>
  <Step title="Create the report">
    Click **Create Report** and select **Comparison Groups**.

  </Step>

  <Step title="Select account and timeframe">
    At the top of the report, select which account and timeframe you want to segment ads for.
  </Step>

  <Step title="Define ad groups">
    Select the platform from the dropdown on the left of the first row, then name your segment (e.g. "Static", "Video", "Product").
  </Step>

  <Step title="Add filters">
    Using the **Add filter** button, select filters to capture the ads you want in each segment (e.g. Ad Types for each segment).
  </Step>

  <Step title="Add more groups">
    Click **Add Group** to add as many segments as you want.
  </Step>
</Steps>

## Using the Report

Once you've defined your segments, the reporting UI below the segment editing section provides the same tools as the Top Performers report:

* Choose a visualisation: Grid view (default), bar chart, or time series.
* Scroll down to see a data table.
* Click into any group in Grid view to see a side panel of the ads in that group.
* Add or change metrics at the top of the visualisation.

As with the Top Performers report, you can save and share your report using the buttons at the top right. For more on the reporting UI features, see the [Top Performers Report](/knowledge/reporting/creative-insights/top-performers).
