Google has worked hard to create technology that makes the advertising on our own sites, and those of our partners, as relevant as possible. To date, we have shown ads based mainly on what your interests are at a specific moment. So if you search for [digital camera] on Google, you'll get ads related to digital cameras. If you are visiting the website of one of our
AdSense partners, you would see ads based on the content of the page. For example, if you're reading a sports page on a newspaper website, we might show ads for running shoes. Or we can show ads for home maintenance services alongside a YouTube video instructing you on how to perform a simple repair.
This kind of tailored advertising does raise questions about user choice and privacy questions the whole online ad industry has a responsibility to answer. Many companies already provide interest-based advertising and they address these issues in different ways. For our part, we're launching interest-based advertising with three important features that demonstrate our commitment to transparency and user choice.
- Transparency - We already clearly label most of the ads provided by Google on the AdSense partner network and on YouTube. You can click on the labels to get more information about how we serve ads, and the information we use to show you ads. This year we will expand the range of ad formats and publishers that display labels that provide a way to learn more and make choices about Google's ad serving.
- Choice - We have built a tool called Ads Preferences Manager, which lets you view, delete, or add interest categories associated with your browser so that you can receive ads that are more interesting to you.
- Control - You can always opt out of the advertising cookie for the AdSense partner network here. To make sure that your opt-out decision is respected (and isn't deleted if you clear the cookies from your browser), we have designed a plug-in for your browser that maintains your opt-out choice.
