How does Criteo protect your data?
Criteo builds audiences from our unique commerce data set, which is built as a result of trillions of customer journeys that result in over $900 billion in annual ecommerce transactions.
Criteo makes sure that any data collected is aggregated and cannot be linked back to an advertiser’s business.
To protect all data from advertisers who are part of our cooperative, any segments available for targeting are aggregated based on the following principles:
To respect user privacy, we make sure that no advertiser can directly target a given user. Therefore, each segment is made up of at least 5,000 unique IDs.
To protect our clients, we make sure that no advertiser can directly target an entire user base. Therefore, each segment is made up of at least 10 partners (on average each audience contains 500 partners), and the largest contributing partner participates on average up to 20% of its unique IDs.
This means that no advertiser can directly target a brand that is sold through a single domain. For example; if an advertiser decides to target a specific brand name, at least 10 partners in our network sharing products from that brand.
Managing marketer and individual consumer privacy
To protect the marketers who are part of our network as well as the privacy of users, all Criteo audience segments made available are fully privacy-safe and built using data inputs that are not re-identifiable or attributable to any marketer’s business.
An available Criteo audience segment in any market must meet all of the following data protection principles:
Minimum of 5,000+ unique user IDs
Minimum of 10+ partners
Avg. partners per category segment: 500
Avg. partners per brand segment: 100
No advertiser contributes more than 49% of unique user IDs for a given segment
No advertiser can directly target another advertiser’s users
