Block cookies and data uses in Ad Manager
This article is for the Google Ad Manager product only. It doesn't apply to other Google products.
You can block other buyers from showing ads based on user interest categories or remarketing. The categories you can block are:
- Data collection: 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.
