Official: Google AdWords Adds Impression Share Metric
Barry Schwartz on July 6, 2007 at 9:37 am
The new metrics include:
- Impression Share (IS): The percentage of times your ads were shown out of the total available impressions in the market you were targeting. This metric is available at the campaign and account level for search.
- Lost IS (Rank): The percentage of impressions lost due to low Ad Rank (cost-per-click bid x Quality Score).
- Lost IS (Budget): The percentage of impressions lost due to budget constraints.
