New York—BPA Worldwide has launched Ad iCompli, a service that tracks online advertising campaigns running across multiple websites, including networks and exchanges. Ad iCompli provides media buyers with metrics on online advertising viewability, positioning, engagement and other key performance indicators through a single interface. The service brings together data sets that were previously available only by contracting with multiple vendors, the organization said in a statement. A BPA analyst documents the findings in an evaluation at the conclusion of the campaign. The service was in research and development for two years and beta tested for almost one year with multiple campaigns from several agencies, said Peter Black, BPA’s senior VP-business development, in a statement.
