Why you may see particular ads

You may see Google ads on Google services (like Search and YouTube), websites, and apps.

Ads on Google Search

You may see ads on Google Search results pages and other Google services such as Google Maps. The ads you see may be based on what you searched for, your location, and the time of day. Other factors that affect the ads you see (based on your Ads Settings) include:

  • Previous search activity that’s related to your current search
  • Other activity on Google services, like Google ads
  • Websites and apps you’ve visited that belong to businesses that advertise with Google
  • Information in your Google Account, like your age range and gender
  • Information we obtain about you from partners

Example

Will is interested in taking a backpacking trip. He searched for “backpacking vacations” on Google and clicked on a search result for a backpacking website. Later, when Will searches for “vacations,” he may see a personalized ad on Google Search results for a vacation destination where he can go backpacking.

Ads on Gmail

When you’re using Gmail, you might see ads at the top of your inbox. The ads you see could be based on factors such as the messages in your inbox and the searches you’ve done. For advertising purposes, Gmail information is only used for ads within Gmail. We also do not share your personal information with advertisers, unless you have asked us to.

The process by which ads are shown in Gmail is fully automated. Nobody reads your emails in order to show you ads. Learn more
