...release of version 13 of the Adwords API. Some of the new additions to version 13 include:

• New geo targeting options: Target multiple geographic levels (countries, regions, metro areas, and cities) within a single campaign, target specific regions of multiple countries in a single campaign, and setup negative targeting for specific regions (for example, target the United States with the exception of Alaska).
• New reports: Generate Search Query Performance and Geographic Performance reports using ReportService and DefinedReportJob.
• Mobile image ads: Use the new MobileImageAd ad type to create graphical advertisements for the mobile content network.

Secondly, the team at the Google Adwords blog provided some insight on how to best leverage the new Impression Share reporting.

Impression share is a metric that represents the percentage of impressions your ad received out of the total available impressions in the market you're targeting. The Impression Share report, available through the Report Center, gives you insight into how you stack up against others in your industry, helping you make more effective changes to your campaigns and boost traffic.
