About privacy and interest-based ads

A cornerstone of interest-based advertising throughout the online advertising industry is to convey to users how their online browsing activities are used to improve the ads they see online, and to give people meaningful choices over how that information is used. Google offers users several ways to control the information that's gathered through interest-based advertising.

Here at Google, we strive to give users easy access to and control over the information that's gathered through interest-based advertising. Here's what Google offers:

  • Visibility and control over interest categories: Through Ads Settings, users can view, add, and remove the categories that are used to show them interest-based ads across the Google Display Network. We don't use sensitive interest categories such as health or financial information, and categories designed for children.
  • Opt-out options: With Ads Settings, users can opt out of interest-based ads, including remarketing. This means, however, that they'll probably see advertising that's less relevant across the Google Display Network.
  • Education within ads: Users can learn more by clicking the "Ads by Google," "Ad Choices," or similar links they see on ads throughout sites included in the Google Display Network.

As the industry continues to evolve, several groups, including the Internet Advertising Bureau (IAB), Network Advertising Initiative (NAI), and the Internet Advertising Bureau United Kingdom (IAB-UK), have developed guidelines for advertisers, publishers, ad networks, and other groups involved in online advertising.
