While not brand new, it's new to the industrial/business-to-business marketer.
And it's worthy of your consideration.
This service places your ad/banner in front of people that have visited your site OR were searching for your products on search engines, and then visited other sites. Have you ever been on a site then afterwards been presented with an ad on another site for what you'd been looking or searching for earlier? This is that.
This is hyper-targeted and hyper-reported. This is next-level search marketing. We see it as going hand in hand with Search Engine Optimization and Pay Per Click programs.
The next rail.
