Google Adwords Ads Share of Voice Measurement
July 9, 2007 – 8:12 amLooking for another way to measure the ROI and overall effectiveness of your Google AdWords campaigns? The new Impression Share measurement gives you just that - indicating how often your ad appears with search results in comparison with the number of times that the search was performed.
Here are the details on what you’ll see:
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.
