In an announcement today, Google said it is offering a new way for publishers to share Publisher-provided identifiers (PPIDs) with Google's programmatic demand to better customize ads, targeting, and advertising experiences. "By helping publishers expand the use of their first-party identifiers to more transaction types, like the Open Auction, our partners will be able to show ads that are more relevant to their audiences, which will increase the value of their programmatic inventory," said Steve Swan, Product Manager, Google Ad Manager.
How do PPIDs work?
A "Publisher provided identifier or PPID allows publishers to send Google Ad Manager an identifier for use in frequency capping, audience segmentation and targeting, sequential ad rotation, and other audience-based ad delivery controls across devices," according to Google's documentation on the topic.
How the new system works.
The announcement says that the new form of PPID sharing will both protect privacy and help publishers and advertisers. Before sharing PPIDs with Google demand, Ad Manager turns them into per-publisher partitioned IDs, so users cannot be identified across other publishers' sites and apps. Then Google Ads and Display & Video 360 aggregate the anonymized data from participating publishers to help build audience segments. Using these segments, advertisers can programmatically deliver relevant ads on publishers' sites and apps based on first-party data.
In addition to helping publishers earn more revenue in the auction, the data also unlocks core functionality for advertisers, like cross-device reach, frequency management, and creative optimization in programmatic inventory without third-party cookies or other identifiers present.
The announcement also emphasizes that advertisers who will be able to build segments off of the PPID data will not be able to see individualized information or user data, "and because PPIDs are unique to each publisher, there is no way to match identifiers or create profiles across sites," added Swan.
What is first-party data?
First-party data is information that websites, advertisers, and publishers collect directly from users and searchers (that they give voluntarily). This includes things like the actions they take on your websites, the data they submit to forms, social data, survey information, and data that already exists in the company's CRM.
