Our advertising system is designed to show the right ad to the right person at the right time. Because ads should be just as useful as any other information on the web, we try to make them as relevant as possible for you. Over the coming weeks, we’re making improvements to provide greater transparency and choice regarding the ads you see on Google search and Gmail. Soon, you’ll be able to learn more about these ads by clicking the "Why these ads" link next to ads on Google search results and Gmail.
“Why these ads” gives you transparency
The perfect search ad answers your query and gets you what you’re looking for quickly. When you click the “Why these ads” link, you’ll find information about why you’re seeing a particular ad and how it’s personalized for you. If you’re searching for a local restaurant while you’re on vacation in Hawaii, you would see ads for restaurants that are nearby, rather than restaurants in your hometown. Or if you’re researching flat-panel televisions, and performing a series of similar searches in quick succession, you could see ads based on the query that you just entered, or based on a few recent and related queries within a single browser session. By considering the language you’re using, your geographic location and various other indications, we’re able to show you the best ads possible. We’ve been showing ads in this way for years as a way to help you quickly find what you're looking for.
Ads Preferences Manager gives you choice
You can also go to the Ads Preferences Manager to make changes that improve the ads that you're seeing, including blocking specific advertisers you’re not interested in or turning off ads personalization entirely (of course, you can change your mind at any time). Here’s a video from our lead software engineer, Diane Tang, with more background:
We regularly experiment with new ways to improve our ads to make them more relevant and to help marketers grow their businesses. When we run these experiments, we’ll continue to explain why the ads are showing when you click the “Why these ads” link.
As we’ve done with display ads, we’re committed to giving you notice and control over the ads that you see. We’re always working to deliver the perfect ad, and we know that it’s important to have a choice about the kinds of ads that are shown to you. If you don’t wish to see personalized ads, the choice is yours.
