Tokyo, April 5, 2018 --- D.A.Consortium Inc. (DAC) and its consolidated subsidiary Platform One Inc. (P1) are pleased to announce a collaboration with Integral Ad Science (IAS) to begin eliminating ad fraud in all advertising campaigns through MarketOne®, one of Japan’s largest DSPs provided by P1.

DAC and P1 have long worked to improve the safety and transparency of ad delivery through aggressive ad verification (*1) initiatives (*2). The decision to collaborate with IAS, an ad verification company, was made to enhance measures to combat ad fraud, a key issue in ad verification along with brand safety (*3) and viewability (*4).

IAS’s feature to detect and eliminate ad fraud will be used in all MarketOne® ad campaigns to remove fraudulent impressions that are categorized as SIVT (*5). In addition to Private Marketplace (PMP) campaigns provided by MarketOne®, this feature will be used for all types of trading, including general open auctions. As ad fraud elimination will utilize pre-bid targeting (*6, refer to chart), advertisers will be able to avoid bidding on fraudulent impressions, thus preventing wasteful costs.

This is the first time for a DSP company to utilize IAS’s pre-bid targeting to measure and eliminate ad fraud by default, from all ad campaigns.

With IAS’s pre-bid detection and blocking functions, the companies plan to reinforce MarketOne® viewability, brand safety targeting and verification capabilities to contribute to campaigns with high viewability as a KPI and eliminate ads from sites that may damage the brand.

DAC and P1 are strongly committed to enhancing the health and development of digital advertising. To that end, they will continue to focus on resolving ad verification issues in programmatic advertising.
