Hi,

I noticed that some of impression share metrics are returned as real numbers ranging from 0.0 to 1.0, but Google Ads reporting tool shows those as percentages with higher precision. E.g. instead of 61.54% shown in reporting tool, API returns 0.62, which is not a big deal unless we want to aggregate these numbers. In this case the rounding error makes significant impact on the result, and the numbers might get off up to 6-7% comparing to the reporting tool. Is there a way to increase accuracy for the values fetched from the API?

Here are some affected metrics:

TopImpressionPercentage

AbsoluteTopImpressionPercentage

Hi Dmitrii,

Thanks for posting your concern.

My apologies also for the delayed response as I discussed your issue to the rest of the team.

Could you provide the complete report definition together with the customer ID via Reply privately to author option? Also, could you provide sample reports generated in Google Ads UI and AdWords API where I can see the discrepancies in total counts of impression share metrics.

Regards,
