DAC’s ”Data Exchange” service on “AudienceOne®” to begin data collaboration with
“Qiita,” a technical information sharing site for programmers
~to enable ad delivery to engineers and designers~

Tokyo, March 26, 2019 ---D.A.Consortium Inc. (DAC) announced today that Increments Inc. (Increments) will begin providing data of its technical information sharing site for programmers ”Qiita(*3)”to Data Exchange(*2), a service available on DAC’s data management platform (DMP) AudienceOne®(*1). This collaboration will enable companies who use AudienceOne® to deliver ads to Qiita users, such as engineers and designers, on MarketOne®(*4) and a variety of other platforms

AudienceOne®, developed and provided by DAC, is one of Japan’s largest DMP with a huge volume of data related to its 480 million monthly unique browser cookies, 100 million mobile ad IDs, and more than 1 trillion data points, which it analyzes to provide high-definition third-party data. Increment’s Qiita is a programming information sharing community site with 5.5 million users, primarily IT engineers and designers in their 20s and 30s. Qiita is highly regarded for its ability to provide technical programming information by producing search results regarding programming questions with articles that enable users to reference the know-how of other users.

With this data collaboration, companies will be able to use the AudienceOne® management screen and based on Qiita user browser history information, target specific professions, such as engineers, as well as specific programming languages, such as Python or Ruby, to deliver ads on any platform linked with AudienceOne®.

Furthermore, by bridging AudienceOne® demographic data with AudienceOne® lifestyle data, even more detailed targeting for ad delivery will be possible. For example, by using data provided by Qiita regarding such attributes as estimated age or estimated income and then combining it with AudienceOne® data, companies can approach “young engineers with a certain level of income” or “users who are engineers and have a high probability of having approval authority” in the area of technical expertise they are seeking.

Through the use and application of data, DAC will support the optimization of client companies’ marketing activities and customer relations to contribute to the ongoing evolution of the online advertising market.

(*1) AudienceOne® integrates various data to analyze and visualize users’ behavior, CRM, advertising campaign and panel survey results, which provide marketers an environment where they can pursue new user acquisition and improve LTV of existing users. (Japanese only)
