Opt out of seeing personalised ads

Ads are essential to fund many websites. When you opt out, you'll still see ads by Google – they just won't be based on topics that you like, your visits to advertisers' websites or demographics. Instead, they'll be based on factors such as the content of the page or your general location.

Here are some other things that you can do to control the ads that you see:

• See fewer ads online and support the websites you visit with Google Contributor
• Turn off ads personalisation for the Google ads you see when you're signed out and those from 100+ other online ad networks through AdChoices

Opting out doesn’t stop personalised ads that aren’t served by Google. So, when you browse the internet and see a website, video or app that uses advertising services by other companies, you may still see personalised ads.

To opt out of seeing personalised ads on other ad networks, you can use a cross-industry opt out tool or control that works for your browser or device. Find out more

Do you use a few different browsers on your computer? Even if you've opted out of personalised ads by Google on one browser (such as Chrome), you may still see personalised ads by Google on your other browsers (such as Internet Explorer and Safari). The same applies if you use multiple computers or devices. That’s because two of the three Ads Settings controls (“Ads Personalisation on Google Search” and “Ads Personalisation Across the Web”) only work for the browser or device that you’re using. You’ll need to opt out of those two settings on the other browsers and devices that you use, too.

To avoid multiple opt-outs, you can sign in to your Google Account to opt out of “Ads Personalisation”. This opt out will work across all devices and browsers where we know that you’re signed in to your Google Account.

Do you delete or clear your browser’s cache and cookies? If you’ve cleared your cookies after opting out you may have undone your opt out for that browser. You may need to opt out of seeing personalised ads again on your browser. You can also install an extension like Protect My Choices.

Google uses cookies for many different purposes, including personalising ads and identifying your Ads Settings. If your browser is set to block cookies, you may see some hiccups in your experience with Google services, including with Ads Settings.

To serve ads in services where cookie technology may not be available (e.g. in mobile apps), Google may use other identifiers that perform similar functions to cookies. To opt out of personalised ads in mobile apps:

Android

1. Open the Google settings app on your device (called Google Settings or Settings, depending on your device)
2. Scroll down and tap Google
3. Tap Ads
4. Switch on Opt out of interest-based ads or Opt out of Ads Personalisation

iOS

Devices with iOS use Apple’s Advertising Identifier. To find out more about limiting ad tracking using this identifier, visit the Settings app on your device.
