Google launched a new report for Adwords advertisers to better understand their geo-targeting performance. The Geographic Performance Report provides metrics including regions, metropolitan areas, and cities on 1 of the 3 levels of your choice: account, campaign or ad group.
Together with Google’s Adwords conversion tracking, your global business can target locations of your choice more cost-effectively based on each location’s performance down to the city level. However, the Geographic Performance Report is only available from 27 May 2007 and aggregates data only on a daily level.
Due to a threshold on impressions for our reporting calculations, doing aggregations of geographical data across multiple days will provide the correct number of clicks – although it may report fewer impressions. A lower number of impressions results in inflated CTRs. For this reason, we are only offering ‘Daily’ views in order to preserve the accuracy and precision of the impression counts and CTRs in your Geographic Performance report. If you want to see aggregate geographic data across multiple days, we suggest you run a Geographic Performance report for each of the days you want include and add the figures for the geographic areas of interest.
