Impression share refers to the percentage of times your ads are displayed compared to the total number of times they could have been shown. It is a metric used in online advertising campaigns to measure the visibility and reach of your ads. A high impression share indicates that your ads are frequently appearing in search results or on websites, while a low impression share suggests that your ads are not being shown as often as they could be. Monitoring and optimizing impression share can help improve the effectiveness and performance of your online advertising efforts.
