[Google Ads API) Data freshness of metrics.search_budget_lost_impression_share and metrics.search_impression_share

[Mat]

Hi,

I noticed that the data freshness of the various ...impression_share metrics is different for shopping vs. search campaigns. While in search campaigns those data usually are available for yesterday, in shopping campaigns they usually are delayed for another day.

In the Google Ads UI, you'll see a "—", if the data is not available yet. 

In the Google Ads API on the other hand, those metrics are of the type "DOUBLE", hence the value of "metrics.search_budget_lost_impression_share" will be returned as 0.0, even if the real value is not available yet.

As a workaround to determine, if the real value of "metrics.search_budget_lost_impression_share" is already available, I came up with the idea, to check if "metrics.search_impression_share" returns a value > 0.0. Because "metrics.search_impression_share" is returned as 0.0 if the real value is not available yet and as some value between 0.0999 and 1 it it is. 

And to assume, that if metrics.search_impression_share has a value >= 0.0999, the real value of metrics.search_budget_lost_impression_share is already available too, even if it is still returned as 0.0.

So my question is: can I assume that metrics.search_budget_lost_impression_share and metrics.search_impression_share are always of the same data freshness (for the same campaign)?

Hi Mat,

I can't say whether this will happen 100% of the time, but according to the Data Freshness document, most metrics such as impression share will be updated at 6:00 am PST. This should be reflected in the API as well.
