This metric is calculated by taking the number of impressions your ad received divided by the total number of impressions your ad was eligible to receive.

Which metrics to view
Here are some metrics to help you understand your impression share:
- Search impression share: The impressions you’ve received on the Search Network divided by the estimated number of impressions you were eligible to receive.
- Display impression share: The impressions you’ve received on the Display Network divided by the estimated number of impressions you were eligible to receive.
- Search lost IS (budget): The percentage of time that your ads weren't shown on the Search Network due to insufficient budget. This data is available at the campaign level only.
Note: In Report Editor, Search lost IS (budget) is available in the Campaigns report, but not in the Ad group report. As of June 2022, the Search lost IS (budget) metric was removed from any previously saved reports that also used “Ad group”, “Search Keyword”, or “Label (Ad group)”.
- Display lost IS (budget): The percentage of time that your ads weren't shown on the Display Network due to insufficient budget. This data is available at the campaign level only.
Note: In Report Editor, Display lost IS (budget) is available in the Campaigns report, but not in the Ad group report. As of June 2022, the Display lost IS (budget) metric was removed from any previously saved reports that also used “Ad group”, “Search Keyword”, or “Label (Ad group)”.
- Search lost IS (rank): The percentage of time that your ads weren't shown on the Search Network due to poor Ad Rank in the auction.
Note: Lost IS (rank) won't be shown on your Ad groups tab if you ran out of budget at any point during the date range being examined.
- Display lost IS (rank): The percentage of time that your ads weren't shown on the Display Network due to poor Ad Rank.
Note: Lost IS (rank) won't be shown on your Ad groups tab if you ran out of budget at any point during the date range being examined.
- Search exact match IS: The impressions you've received divided by the estimated number of impressions you were eligible to receive on the Search Network for search terms that matched your keywords exactly (or were close variants of your keyword). This is unavailable for Shopping campaigns.
