Questions about ads and your privacy
Does Google listen to my phone calls or read my emails?
No. Google respects that your conversations are personal and private. We don’t use information from your phone calls, emails, or services like Google Drive to influence the ads you’re shown.
Does Google sell or share my personal information?
It’s always your choice to share information with Google. Your personal information isn’t sold or shared with advertisers, publishers like websites and apps, or other companies. The data that advertisers get about their audiences is aggregated and doesn’t share any personal information about you.
How does Google make money?
Google's main source of revenue is from ads on our own sites and apps. Advertisers tell Google the types of audiences they want to reach, and we try to show their ads to people in those groups. Each of Google’s products and services show ads in different ways to help reach new and existing customers.
Google also makes money by helping other sites and apps make money with advertising. These sites and apps use our ad technology to show their ads. We keep a portion of the money that advertisers pay, and the rest goes to the partner site or app.

Let’s say you’re looking for info about guitar lessons using Google Search. If an advertiser tells Google they want to show ads based on the keyword “guitars,” you might be shown an ad from that advertiser. If you click on one of those ads, the advertiser pays Google. If you see the ad and don't click it, the advertiser isn’t charged and Google makes no money.
How does Google make guesses about me?
You can review which categories you’re currently getting ads for in My Ad Center’s Manage Privacy tab. When a business places an ad, it often chooses which categories of people it wants to show its ads to. For example, a roofing service may choose to show its ads to homeowners instead of renters.
Your activity on Google sites and apps is used to determine which categories are most relevant to you, and then show you ads meant for people in that category. If these ads aren't a good fit for your interests, you can update or turn off any category.
Let’s say you use Google Search to look for diapers for a toddler. Based on this, Google might estimate that you’re interested in other products meant for people in the category “Parents of toddlers.”
What if my status is different than the options in a category?
We only show categories that are used for personalized ads, so options for some categories may be limited. Sometimes, you may want to get ads for a different category than what we've estimated.
When you turn off a category, your info for that category will be deleted and that category won't be used to show you ads. If you turn off personalized ads, all of your category info will be deleted and won’t be used to personalize ads.
To turn on or off a category for ads:
- In My Ad Center, select Manage Privacy
.
- Under “Categories used to show you ads,” select the category you’d like to turn on or off.
- On the page for that category, use the toggle to change your setting.
To update a category:
- In My Ad Center, select Manage Privacy
- Under "Categories used to show you ads", select the category you’d like to control or update.
- Select the option that fits your interests.
When you update a category, your changes will be saved within My Ads. You'll start to receive ads meant for people in that category in a few days. If you turn off personalized ads, all of your category info will be deleted and won't be used to personalize ads.
Questions about your activity on Google and ads
How does Google use my saved activity?
Your saved activity is used on Google for two types of things: personalized product experiences and personalized ads. You can decide if your activity is used for either and if it is saved to your Google Account.
Personalized product experiences use your activity to give you better recommendations in Maps, Search, and other Google services.
If you search for chocolate cake, and then search again for “how to make,” Google might be more likely to predict that you’re searching for “how to make chocolate cake.”

Personalized ads use your activity to help show you more relevant and interesting ads on Google services like Search and YouTube.
If you’ve recently searched for info about how to make a chocolate cake, you might see an ad on YouTube about cake baking supplies.

How does Google use info about where I've been to personalize ads?
When you use Google services, Google estimates the general area that you’re searching from and saves that info with your Web & App activity. This location information helps Google show you more relevant ads. You can turn on or off using these areas for personalized ads at any time.
- If “Areas where you’ve used Google” is on and you search for coffee, you might see an ad for a local coffee shop.
- If “Areas where you’ve used Google” is off and you search for coffee, you might see an ad for a coffee shop in a different town.
To control whether the areas where you’ve used Google may be used for ads:
- In My Ad Center, select Manage Privacy
- Under "Activity used to personalize ads," select Areas where you’ve used Google.
- Select the toggle to turn on or off Use areas to personalize ads.
- Confirm your preference by selecting Turn off.
This setting affects the ads on all Google sites and apps.
When you turn off Areas where you’ve used Google for ads, it won’t be used to help personalize the ads you see. The area’s where you’ve used Google may still be saved to your Google Account, and you may still get personalized recommendations on Google services.
Questions about customizing your ad experience
Why am I still being shown an ad, even though I blocked or reported it?
Ad blocking is imperfect and sometimes we miss blocking an ad for you. You might be seeing an ad even though you've blocked or reported it for the following reasons:
- Google doesn't show every ad on the web. If you’re on a non-Google site or app, a different ad technology company might be showing you that ad.
- Advertisers use many different formats and styles of ads for the same products, and you might be seeing an ad similar to the one you blocked.

Why am I still being shown ads related to a category I've turned off?
When you turn off a category, your info for that category will be deleted and that category won't be used to show you personalized ads on Google services, like Search and YouTube.
- If you’re on a non-Google site or app, a different ad technology company might be showing you that ad.
- If you're on a Google site or app, you might see an ad that seems related to a category you’ve turned off because of other preferences you’ve set in My Ad Center or because the ad is contextual. Contextual ads are based on factors like the time of day, the topic of the website you're visiting, your approximate current location, or your current search.
Why can't I block sensitive topics entirely?
We’ll do our best not to show you ads about the topics you limit. In some cases, you might still see an ad containing images related to the topic you’ve limited. For example, you might see an airline ad featuring someone holding a glass of champagne. This isn’t an alcohol ad, even though the ad shows alcohol.
In other cases, you might still be shown an ad about a topic you’ve limited if you search for info about one of those topics or you watch a video related to those topics.
Why can’t I limit more sensitive topics?
At the moment, you can limit ads about: alcohol, dating, gambling, parenting and pregnancy, as well as weight loss. These were selected based on extensive user research into what topics people find most sensitive. As we continue to conduct research, we may include additional topics in the future.
Do the choices I make in My Ad Center affect the ads I see on other sites?
The choices you make in My Ad Center affect the ads you're shown on Google services like Search and YouTube. When you turn on or off personalized ads in My Ad Center, that choice affects whether or not ads are personalized on Google services as well as sites that partner with Google to show ads.
Not every website partners with Google to show ads. Turning on or off personalized ads in My Ad Center does not affect the kinds of ads from other ad technology companies or the ads you're shown on sites that have their own ads platforms.
