YouTube Interest-based Advertising and You
We want to make advertising on YouTube as useful and interesting to you as possible. For some pages, we choose ads that we think will reflect your interests, based on the type of videos that you prefer to watch, as well as your site activity (uploading, for example). Additionally, YouTube uses information based on the type of pages that you visit on websites that are members of the Google content network.
To learn more or edit your advertising preferences, please go to the Ad Preferences Manager.
