To keep you safe and protect your privacy while you browse, Chrome has ad privacy features that give you more control over how advertisers can personalize and choose which ads to show you.
Your topics of interest are noted by Chrome and are based on your recent browsing history. Sites can also store info with Chrome about your interests. As you keep browsing, Chrome may be asked to share stored info about ad topics or site-suggested ads to help give you a more personalized ad experience. To measure the performance of ads, limited types of data can be shared among sites and apps.
You can opt out of these features in your Chrome settings anytime. Whether an ad you see is personalized depends on these settings, your cookie settings, and if the site you view personalizes ads.
Edit ad privacy settings
- On your device, open Chrome.
- At the top right, select More
Settings.
- Select Privacy and security
- Select the ad feature you’d like to turn on or off.
To personalize your ad experience, Chrome notes your topics of interests based on the sites you browse, how frequently you visit them, and other considerations. Even without ad topics, sites can still show you ads but they may not interest you. Chrome can share up to 3 topics at a time with sites. You can block topics and categories of topics you don’t want shared with sites. When you block a topic, Chrome won't share that topic again, but you may still get ads related to the topic. To further protect your privacy, Chrome automatically deletes your topics that are older than 4 weeks.
To block a topic:
- On your device, open Chrome.
- At the top right, select More
- Select Ad privacy
- Under "Active topics," select topics to block.
To block a category of topics:
- On your device, open Chrome.
- At the top right, select More
- Select Ad privacy
- Turn off the categories you want to block.
Tips:
- Based on your recent browsing history, it may take a while for a list of topics to appear. You can block categories of topics at any time, even if a list of topics hasn’t appeared. You may not get a list of topics if the sites you visit don't support this feature.
- When on a site, you can check if Chrome shared your topics of interest with the site. In the address bar, select View site information
To help deliver a personalized ad experience, sites can recommend and then store ad suggestions about things you may like. As you continue to browse, you may get ads based on suggestions from related sites. Chrome automatically deletes suggestions that are older than 30 days, but they may reappear if you revisit that site.
If you don’t want a site to suggest ads for you, you can block the site. Once blocked, any associated ad suggestion data is deleted. Blocked sites will no longer store ad suggestions with Chrome, but you may still get ads related to those sites.
To block sites:
- On your device, open Chrome.
- At the top right, select More
- Select Privacy and security
- Under "Sites," block a site from the list.
Tips:
- Based on your recent browsing history, it may take a while for a list of sites to appear. You also may not get a list of sites if this feature hasn’t been adopted by the sites that you visit.
- When on a site, you can check if the site is suggesting ads for you. In the address bar, select View site information
