About Google ads

You can advertise your business all over the web with Google Ads, earn revenue from your website with AdSense, or monetize your app with AdMob.

As you browse the internet, use mobile apps, read your email, or shop online, you see ads. Google shows ads on Google products like Search, YouTube, and Gmail. Google's ad network also shows ads on 2+ million non-Google websites and apps. It is one of many ad networks that can personalize ads based on your online activity.

The way Google saves your ad settings has changed. Learn more about how Google uses cookies for ad personalization

Ads that Google shows can be personalized based on many factors, like the types of websites you visit or mobile apps you've installed. If ad personalization is off, ads may still use non-personal data, such as your general location or the topics on the website or app you're looking at.

Where personalization comes from

Google can show you ads based on many factors, including:
  • Types of websites you visit, and mobile apps you have on your device
  • Cookies on your browser and the settings in your Google Account
  • Websites and apps you’ve visited that belong to businesses that advertise with Google
  • Your activity on another device
  • Previous interactions with Google’s ads or advertising services
  • Your Google Account activity and information

You can control how Google personalizes Google ads, or turn off personalization of Google ads, at Ads Settings.

When showing you personalized ads, Google will not associate an identifier from cookies or similar technologies with sensitive categories, such as those based on race, religion, sexual orientation, or health.
