CPM Advisors operates the CPMatic.com advertising platform which allows marketers to buy optimized display advertising, and our system now has 94.3% reach (187.1 million monthly uniques) in the United States according to data from comScore (September 2009 dataset).

Google/Doubleclick has this week enabled pixel-based targeting across their exchange, including the Google Content Network, and we are now able to offer brands and partners the ability to instantly do retargeting (also known as remarketing or remessaging) campaigns across a variety of ad platforms including the entire Google Content Network which numbers about 159.7 monthly unique visitors monthly: CPMatic.com offers self-service retargeting which you can setup and be live on within 10 minutes with a credit card.

Audience-targeted retargeting campaigns have a typical 3x to 20x better ROI than regular site-targeted display ads: we think it’s a great way especially for search marketers to get started with display ad buying.
