Search Impression Share is this metric found by dividing the number of impressions received on the Search Network divided by the total estimated number of impressions you were eligible to receive.
Search Impression Share is a great indicator of the strength of your keyword set in Google AdWords. Having a very high Impression Share for both Exact Match and Standard means that you can feel confident with your coverage. A strong coverage is good for business! Search Impression Share also helps guide you to expand your keyword set through Search Query Reporting or encourage you to add more negative terms to improve campaign performance.
