Using natural language processing and machine learning, Peer39’s algorithms understand a page’s meaning and sentiment instead of just scanning for key words and plugging in advertising like Google’s Ad Sense. By pulling out the true meaning of any given page, Peer39 is able to deliver the most relevant and effective display and text advertising available and it is a real company to watch over the coming months.
A quick glance at their page shows that their business structure is similar to that of Google’s, where advertisers can buy space and publishers can sell it. The difference between the two, other than the fact that Google is a giant, is that Peer39 offers a solution that would appear to be more sophisticated than Google’s given the fact that the possibilities for targeting are superior.
