About Google Ads
As you browse the Internet, read your email, and shop online, you’ve probably noticed Google Ads on these sites related to what you’re searching for or viewing. For example, your Google Search results page may show text ads similar to a search phrase you just typed; or, your favorite blog may show interactive ads related to the content on the page. Google Ads can also appear on Gmail, Google Earth, and Google Maps.
So, why do we show ads and why might you see particular ads?

Why you may see particular ads
You may see Google ads on Google Search and related products, Gmail, and sites across the web.
On Google Search
You may see text ads on Google Search results pages and other Google products such as Google Maps. The ads you see may be based on what you searched for, your location, and the time of day. Depending on settings you've chosen, here are some factors that also determine the ads you see:
- Recent, previous searches related to your current search
- Google Web History and the settings in your Ad Settings
- Websites you’ve visited that belong to businesses that advertise with Google
- Non-personally identifying information in your Google account, like your age and gender
- Previous interactions with Google’s ads, advertising services, or search results
You recently clicked a search result for a kayaking website. Later, when you search for “vacations,” you might see an ad for a vacation destination where you can kayak.
You may see text or image ads in Gmail as you read your messages. The ads you see may be based on many of the same factors as ads in Google Search as well as additional factors like the messages in your mailbox.
You’ve recently received lots of messages about photography and cameras. In Gmail, you may see an ad with a deal from a local camera store.
Ad matching in Gmail is fully automated; no humans read your email in order to show you ads.
On sites across the web
You may see ads in a variety of formats (text, image, video) on sites and apps that partner with Google, also known as the Google Display Network. The ads you see may be based on the content of the site you’re viewing and your recent geographic location, among other factors. Depending on settings you've chosen, here are some factors that also determine which ads you see:
- Types of websites you visit, and mobile apps you have on your device
- The DoubleClick cookie on your browser and the settings in your Ads Settings
- Websites and apps you’ve visited that belong to businesses that advertise with Google
- Previous interactions with Google’s ads or advertising services
- Your Google profile, including YouTube and Google+ activity
