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 are based on your activity while you were signed in to Google. Google does 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

Ads on YouTube

You may see different types of ads on YouTube. The ads you see may be based on the content of the video you’re viewing, among other factors. Other factors that determine the ads you see (based on your Ads Settings) include:

  • Information in your Google Account, like your age range and gender
  • Other activity on Google services, like Google ads
  • Types of websites you visit and mobile app activity on your device
  • Websites and apps you’ve visited that belong to businesses that advertise with Google
  • Information we obtain about you from partners

Example

Rachel likes watching videos about cooking on YouTube. He may see ads related to cooking classes in her area when she’s using YouTube.

Ads on non-Google websites and apps

You may see different types of ads (ex: text, image, video) on more than two million non-Google websites and apps that partner with Google to show ads. The ads you see may be based on the content of the website or app you’re viewing and your recent geographic location, among other factors. Other factors that determine the ads you see (based on your Ads Settings) include:

  • Types of websites you visit and mobile app activity on your device
  • Websites and apps you’ve visited that belong to businesses that advertise with Google
  • Your activity on another device
  • Other activity on Google services, like Google ads
  • Information in your Google Account, like your age range and gender

Example

Nick enjoys visiting websites and blogs about bird watching. He may see ads related to birds and bird watching when he visits the websites and apps that partner with Google to show ads.

Ads that use information provided by advertisers

You may see ads from advertisers based on information you gave to them, like your email address or mailing address. Advertisers can provide this information to Google in order to advertise to you on Google services (ex: Search, YouTube).

Example

Jim gives his Gmail address to a department store when he buys a new blender, and his email address gets put into the store's customer database. This department store then shares its list of customer emails, including Jim's, with Google, so that it can advertise to its customers. Later, when Jim is signed in to Google and uses Google Search, he may see an ad offering a discount from the department store.

Example
 
Dorothy gives her mailing address to an online athletics store when she buys a pair of sneakers. This athletics store puts Dorothy's mailing address in its customer database, then shares its list of mailing addresses with Google. Google matches this list with addresses associated with Google accounts (ex: addresses saved in Google Maps, or addresses from location history). Later, when Dorothy is signed in to Google and is browsing online, she may see an ad from the athletics store.
