Performance Max campaigns are only available at Campaign level

Overview

Performance Max (PMax) campaigns in Google Ads are only available at the campaign level through the Google Ads API.

If you request data using Ad Group or Ad level dimensions, Performance Max campaigns will not be returned in the results.

This behavior is inherent to the Google Ads API and is not specific to Catchr.

Why does this happen?

Performance Max campaigns do not expose traditional Ad Groups or Ads in the same way as Search or Display campaigns.

When you:

• Add Ad Group dimensions

• Add Ad dimensions

The API automatically excludes Performance Max campaigns because they do not support those levels in standard reporting.

As a result:

• Your dataset may look incomplete

• PMax campaigns will be missing from your report

How to retrieve Performance Max campaigns correctly

To ensure Performance Max campaigns are included in your report:

Use only:

• Campaign-level dimensions (e.g., Campaign name, Campaign ID)

• Account-level dimensions

Do not use:

• Ad Group dimensions

• Ad dimensions

Example

If you want to analyze Performance Max results, build your query with:

• Date

• Account

• Campaign

• Metrics (Clicks, Impressions, Conversions, Cost, etc.)

Avoid adding:

• Ad Group name

• Ad ID

• Ad type

Summary

Performance Max campaigns in Google Ads:

• Are available only at Campaign level

• Are excluded automatically when using Ad Group or Ad level dimensions

• Must be queried using Campaign or Account level dimensions only

If PMax campaigns are missing from your report, check your selected dimensions first.
