Google Ads Changes in Supported Conversion Field Combinations - Feb. 15th, 2021

To align the behavior between the AdWords API with the Google Ads UI and Google Ads API, Google will be changing which conversion field combinations are allowed by Feb 15th, 2021. As Supermetrics uses the AdWords API, we also need to adjust the behavior of those fields to match.

In many cases we already observe these restrictions in our reports as it was documented in the AdWords API and other combinations result in "no data". We have be updated these on February 2nd, 2021 to throw an "IllegalDimensionMetricCombinationException" error.

The following dimensions will no longer be permitted to be used in combination with the metrics listed after - please update your reporting to prevent errors:

Restricted dimensions:

  • ConversionAdjustment
  • ConversionAdjustmentLagBucket
  • ConversionAttributionEventType
  • ConversionCategoryName
  • ConversionLagBucket
  • ConversionTrackerId
  • ConversionTypeName


  • AllConversionRate
  • ConversionRate
  • CostPerAllConversion
  • CostPerConversion
  • CostPerCurrentModelAttributedConversion
