Today we launched our Mobile Behavioral Targeting Solution, which means all of the powerful behavioral targeting options, segments and categories previously only available on our online properties are now available to buyers of our mobile display inventory as well.

Mobile behavioral targeting enables advertisers to reduce advertising waste and maximize the impact and ROI of their mobile campaigns by targeting consumers who have already demonstrated an interest in specific product categories. Over one hundred behavioral segments across popular advertiser categories such as Automotive, Financial Services, Health, Lifestyle, Life Stages, News and Entertainment, Retail, Technology and Travel are available for purchase.

How does Microsoft measure behavior?

Microsoft Behavioral Targeting works by anonymously tracking behaviors of users and classifying these users into unique segments using information from the following data sources:

. PC Web keyword search behavior from Bing Search

. PC Web Site visits to various sites across the Microsoft network

. Microsoft network data (i.e. Hotmail newsletters, Xbox subscription data)

. Profile data from Windows Live

With Microsoft Mobile Behavioral Targeting, data from these sources and others is factored together along with its relevancy to create hundreds of unique, specific segments. Within these niches are the consumers who are most likely to be receptive to your message. Your mobile ads are served only to users in your desired segments, enabling you to refine your reach and increase your campaign's performance. Simple yet powerful, Behavioral Targeting is one of the most effective and efficient forms of mobile advertising available today.

Here at Microsoft we understand that preserving consumer trust is essential to the success of our business. Microsoft maintains a strong focus on protecting customers' privacy and adheres to high privacy standards. Our Mobile Behavioral Targeting Solutions do not utilize personally identifiable information (like name, address or phone number).

If you're seeking a unique advantage in mobile marketing, there's no better solution than Behavioral Targeting. For more information on these and other Microsoft mobile advertising solutions check out our Mobile Advertising site or send through an email to Jeff.

Update: This feature is open to just US advertisers at this time.
