You can block other buyers from showing ads based on user interest categories or remarketing. The categories you can block are:
- Data collection: (Discontinued) This category will be retired in Q2, 2022. To allow RTB buyers to collect data, please use the new data collection control instead. Ads where a real-time bidding (RTB) call declares that data will be collected for subsequent use in targeting or remarketing. This setting applies to all non-Google buyers.
- Interest-based category cookies: Ads where an RTB call declares that the ad will target consumers based on user interest categories. This setting applies to all non-Google buyers.
- Match-coding and subsequent data: (Web only) Ad Exchange won’t provide cookie matching (match tags) in the creative to buyers that have not won the impression. This control only applies to non-Google buyers participating in the Ad Exchange auction.
- Remarketing list cookies: Ads where any RTB call declares that the ad will target consumers based on remarketing lists. This setting applies to all non-Google buyers.
Note: After Q2, 2022, identifiers on RTB traffic are redacted when you block both "Interest-based category cookies" and "Remarketing list cookies." Prior to that date, you had to block "Data collection," "Interest-based category cookies," and "Remarketing list cookies" for the redaction to occur.
