IS - Impression Share
What does IS mean?
IS means Impression Share and is Google’s calculation of the percentage of impressions that your ads received compared to the total number of impressions that your ads could get. The higher, the better.How do you calculate IS?
You can not calculate IS yourself, Google does this itself by taking the number of impressions and dividing it by the number of total eligible impressions and multiplying that with 100%.
