Netsprint Adserver system is context based – which means that it analyses context of the website, abstract important keywords and use them to mach best ads. We gather only meaningful keywords from websites using statistic and context structure analysis.
Keywords from context are later matched with those added by advertisers to their advertisements. As a result of this process we receive a list of advertisements with visualizations. During the next step system analyzes visualizations and chooses best correlated by taking under consideration various parameters together with contextual correlation score.
Visualizations from the same domain are folded. We believe that only one visualization from each domain should be visible in one placement. This gives users a differentiated visualizations on placement level and increase CTR.
