Many websites and apps use Google services to improve their content and keep it free. When they integrate our services, these sites and apps share information with Google.
For example, when you visit a website that uses advertising services like AdSense, including analytics tools like Google Analytics, or embeds video content from YouTube, your web browser automatically sends certain information to Google. This includes the URL of the page you’re visiting and your IP address. We may also set cookies on your browser or read cookies that are already there. Apps that use Google advertising services also share information with Google, such as the name of the app and a unique identifier for advertising.
If ad personalization is turned on, Google will use your information to make your ads more useful for you. For example, a website that sells mountain bikes might use Google’s ad services. After you visit that site, you could see an ad for mountain bikes on a different site that shows ads served by Google.
If ad personalization is off, Google will not collect or use your information to create an ad profile or personalize the ads Google shows to you. You will still see ads, but they may not be as useful. Ads may still be based on the topic of the website or app you’re looking at, your current search terms, or on your general location, but not on your interests, search history, or browsing history. Your information can still be used for the other purposes mentioned above, such as to measure the effectiveness of advertising and protect against fraud and abuse.
When you interact with a website or app that uses Google services, you may be asked to choose whether you want to see personalized ads from ad providers, including Google. Regardless of your choice, Google will not personalize the ads you see if your ad personalization setting is off or your account is ineligible for personalized ads.
You can see and control what information we use to show you ads by visiting your ad settings.
Here are some of the ways you can control the information that is shared by your device when you visit or interact with sites and apps that use Google services:
