Blocking controls experiments

Blocking controls experiments let you compare different ad categories or ad serving settings. By creating and running these experiments, you can discover if a new variation performs better than your original settings.

The following ad blocking settings are available for blocking controls experiments:

• General ad categories (including first level sub-categories)
• Sensitive ad categories
• Ad serving opt-outs
