Overview
Custom Datasets for Google Ads allow you to extend Polar beyond the default Google Ads schema by selecting additional metrics and dimensions tailored to your reporting needs.
This feature is especially useful for teams that require more granular breakdowns, custom reporting views, or access to specific Google Ads fields not included out of the box. By creating a Custom Dataset, you can:
Access advanced or less common Google Ads fields
Build more detailed performance breakdowns
Support custom metrics and reporting use cases that aren’t possible with default data alone
How-To Configure a Google Ads Custom Dataset
Follow the steps below to create a Custom Dataset in Polar:
Tip: Be intentional when selecting fields. Only metrics and dimensions explicitly added to the dataset will be available for reporting.
Navigate to Connectors → Google Ads → Configure.
Click Custom Datasets at the bottom of the configuration page.
Select + Add Custom Dataset.
Choose the metrics and dimensions you want to include, then give your dataset a clear and descriptive name.
Save your Custom Dataset.
⚠️ This step is final. Once saved, a Custom Dataset cannot be edited.
After processing, your data will be available under Google Ads metrics in Polar.

Data Availability, Limitations, and Best Practices
Data Availability & Sync Timing
Custom Datasets do not populate immediately.
Custom Datasets pull in data at a slower rate than standard Google Ads data
Please wait at least 24 hours after configuration for new metrics and dimensions to appear in Polar
In some cases, larger or more complex datasets may take longer to process
Metrics and Dimensions Must Be Included Together
If you want to:
View an existing Polar metric broken down by a new dimension, or
Use a new metric with an existing dimension
You must include both the metric and the dimension in the same Custom Dataset.
Metrics and dimensions are only compatible with each other if they are explicitly defined together in the dataset.
Cost Metric Limitation (Cost Micros)
Due to a Google Ads API limitation:
Cost is returned as
cost_microsin Custom Datasets
To view cost in standard currency:
Pull in the
cost_microsmetric via your Custom DatasetCreate a custom metric in Polar to convert cost micros into your true cost value
Editing or Updating a Custom Dataset
Custom Datasets cannot be edited once created.
If you need to make changes:
Delete the existing Custom Dataset
Create a new dataset with the updated metrics and dimensions
Because of this limitation, it’s strongly recommended to double-check your configuration before saving.
