About ads on Google
As you use Google services, like Search and YouTube, you may see ads. These ads help keep many Google services available for no charge. Ads you see on Google are either personalized, using factors like your choices in My Ad Center, or non-personalized. Open the sections below to learn more about the factors used to show you personalized and non-personalized ads.
Personalized ads on GooglePersonalized ads on Google are ads shown to you based on:
- The choices you’ve made in My Ad Center, like your preferred ad topics and brands.
Learn more about how to customize your ad topics and brands. - Information, such as your age and gender, that you’ve provided in your Google Account or that Google has estimated about you.
Learn more about how to manage and update your Google Account info. - Activity saved to your Google Account, including things you’ve looked for on Google Search, videos you’ve watched on YouTube, apps you’ve installed on your Android device, ads or content you’ve interacted with, and your general area while using Google Services. A general area is larger than 1 square mile, and has at least 1000 users so that the general area of your search does not identify you, helping to protect your privacy. This means that a general area is typically larger than 1 square mile outside of cities. Your activity can come from any device where you sign in to your Google Account.
Learn more about how to control what activity is used to personalize ads. - Activity from sites that partner with Google that is saved to your Google Account.

For example:
- You might see an ad for a new car because you've watched a YouTube video about the best new cars this year.
- You might see an ad on YouTube about cooking because you’ve looked for recipes on Google Search.
- You might see an ad for running shoes because you’ve customized your ads on My Ad Center to see more about the Fitness topic.
Your choices in My Ad Center, like your preferred ad topics and brands, only affect the ads you see on Google services. Those preferences are not used to personalize ads on partner sites and apps. Visit Partner ad settings to control personalized ads on partner sites and apps.
Non-personalized ads on Google are shown to you according to factors like the time of day, the topic of the website you're visiting, your current location, or your current search.
For example:
- You might see a restaurant ad for lunch specials because it is noon in your timezone.
- You might see an ad for a local plumber because you are searching for plumbing services.
About ads on partner sites and apps
Websites, like news sites and shopping sites, and apps often have space reserved for ads. When sites and apps would like to show ads, they can partner with Google or a number of other ad technology providers to manage those spaces and show visitors relevant ads.
Millions of sites and apps partner with Google to help fund their content using ads paid for by advertisers. These partner sites and apps specifically use Google technology to show ads. They show ads with the Google Display Network, a Google platform that helps advertisers show ads on sites across the web.
Ads you see on partner sites and apps are either personalized or non-personalized. Although these partner sites are neither owned nor operated by Google, you can choose whether or not the ads you see on these sites are personalized using the Google Display Network.
Not every website or app uses Google technology to show ads. For example, social media sites and apps may have their own advertising platforms.
Personalized ads on partner sites might be based on your:
- Info that you’ve given that website or app like your email address, age, or gender.
- Interactions with content on that website or app.
- Interactions with ads on that website or app.
- Google Account activity depending on your Google settings.
- Account settings for that website or app.
For example:
- You might visit a news site and see an ad for a cooking magazine because you’ve previously read an article about food on that website.
- You might visit a website and see an ad for a new car because you've read an article about this year’s new cars.
Non-personalized ads on partner sites and apps are shown to you according to factors like the time of day, the topic of the website you're visiting, or your general location.
For example:
- You might see a restaurant ad for lunch specials because you’re reading a blog about lunch recipes.
- You might see an ad for a roofing business because you are on a website about home repair.
