RE: Impressions correct when fetched from product_group_view but lower when fetched from ad_group

Hello Konstantin,

Thank you for raising this concern to Google Ads API forum. I would like to inform you first that I am going to delete your initial post as it contains sensitive information. I just pasted the context of your concern below without the sensitive information.

As your concern is this:

Hello,

we see a behaviour in the API which we cannot explain.

For the same campaign/adgroup (which only contains listing groups) 

- when we fetch the number of impressions from product_group_view we get the correct total number of impressions (18542 - the same as displayed in the Ads UI)
- when we fetch the number of impressions from ad_group the total number of impressions (16401) is too low
- the number of clicks (97) is the same in both cases, as expected

What is the reason for this?

-------ADGROUP--IMPRESSIONS-TOO-LOW------

Hi Konstantin,

I got some clarification from one of our Shopping experts. The product_group_view and shopping_performance_view both count events on products instead of on ads. The campaigns in question are Smart Shopping campaigns, where ads will serve with multiple products. When that happens:

• The ad receives just 1 impression. This is reflected in reports at the ad level or above, such as queries on ad_group_ad, campaign, or customer.
• Each product receives 1 impression. This is reflected in the product_group_view and shopping_performance_view reports, which are at the product level.

Therefore, the counts in product_group_view and shopping_performance_view are not expected to match reports on those other resources.

Let me know if that doesn't clear things up.

Cheers,
Josh Radcliff, Google Ads API Team
