With the data collection and interest-based ads control, you can manage how Google (Google Ads, Display & Video 360) may use data to serve personalized interest-based ads.
When the control is turned on, Google can use data to serve interest-based ads, as well as build and update user profiles for these interest-based ads.
How it works
When you allow data collection and interest-based ads, Google demand (Google Ads, Display & Video 360) can:
- collect user activities on your sites through ad requests, clicks, and conversions.
- build user profiles and then serve interest-based ads.
When you don't allow data collection and interest-based ads, Google demand (Google Ads, Display & Video 360) is not allowed to build user profiles based on data from ad-related traffic on your sites, and Google won’t use existing profiles to serve interest-based ads.
Note: For Google demand to use user profiles for interest-based ads, publishers must contribute data to the creation of these cross-site user profiles. To represent this, this control allows publishers to opt in to both contributing data and using existing profiles to serve interest-based ads, or to opt out of both contributing data to user profiles and using them for interest-based ads.
Update your data collection and interest-based ads setting
By default, the data collection and interest-based ads setting is allowed for Google demand. To change the setting:
- Sign in to Google Ad Manager.
- Click Delivery, then Demand channel settings.
- Under "Data usage and personalization," click Data collection and interest based ads, and choose an option:
- To allow data collection and interest-based ads for the bidding ad source, click the switch on . This setting is the default.
- To not allow data collection and interest-based ads for the bidding ad source, click the switch off .
- Click Save.
What happens when you turn off data collection?
- For Google demand, this control additionally prohibits Google from creating or updating user profiles, and from using existing profiles to serve interest-based ads.
- The number of ads competing to appear on your inventory might decrease, which may decrease your potential earnings.
