Asset Group perf stats don't match it's pmax campaign stats

[Rich Johns]

Given a pmax campaign, my expectation is that performance stats fetched at the campaign level will match the performance stats fetched at the asset group level. They are not. The campaign stats report larger numbers than the asset group stats.

In an experiment I fetched a single day of perf stats for the pmax campaign and the same single day for the pmax campaign's asset groups. 

Here is the query used for the asset group stats:

SELECT asset_group_product_group_view.asset_group, segments.date, campaign.id, campaign.name, metrics.cost_micros, metrics.impressions, metrics.clicks, metrics.conversions, metrics.conversions_value, asset_group.name, FROM asset_group_product_group_view WHERE segments.date >= '2023-03-16' AND segments.date <= '2023-02-16' AND asset_group_listing_group_filter.type != 'SUBDIVISION'

And then to compare asset group stats to campaign stats,  I look at only asset_group_product_group_view result rows of the specified pmax campaign.

I'm expecting the stats of the asset groups belonging to the pmax campaign to equal the stats of the campaign.  Are my expectations incorrect? If not, any insight as to why they are not the same is much appreciated.

Thanks

hi, 

I have the same question is that Can you confirm that the stats of campaign will be sum of all asset_group's stats or not?

Thanks

Hello,

Thank you for your response. 

Please note that we have already replied on that thread that you've already raised with same inquiry with subject: “Stats of Asset group” with the following message:

“With regards to your concern, you mentioned that you want to get the metrics of the campaign from the combined asset group metrics. Please note that the API mirrors the Google Ads UI. Meaning, the Google Ads API should be able to pull the data that the Google Ads UI is showing.

With that being said, can you provide the full (not cropped) screenshots of the campaign / asset_group metrics that you are referring to from Google Ads UI? It would be better if you provide the non-cropped non-redacted full screenshot of this UI report

You may then send the requested information via the Reply privately to the author option. If this option is not available, you may send the details directly to our googleadsa...@google.com alias instead.

Links included in this email:

• Google Ads API - https://developers.google.com/google-ads/api/docs/start “

We strongly suggest to continue discussion in a single thread instead for better tracking of the issue. Hoping for your kind understanding of this.
