Calculation logic for search impression share

[Niranjan Patil]

Hi Team,

We wanted to know how the search impression share is calculated for the period of a week.

For one of the adgroups, the search impression share seen on the Google Ads dashboard for the week of Aug 1, 2022 is 71.43%.

The response from the API for the same is as follows:

Date -> 1 Aug 2022
impressions = 1, search_impression_share = 1.0

Date -> 2 Aug 2022
impressions = 1, search_impression_share = 0.0

Date -> 3 Aug 2022
impressions = 0, search_impression_share = 0.0

Date -> 4 Aug 2022
impressions = 0, search_impression_share = 0.0

Date -> 5 Aug 2022
impressions = 1, search_impression_share = 1.0

Date -> 6 Aug 2022
impressions = 1, search_impression_share = 0.5

Date -> 7 Aug 2022
impressions = 2, search_impression_share = 1.0

We would like to know how the search impression share for the Week of Aug 1, 2022 is calculated as 71.23% from the values shown above.

Let me know if you need additional details.
