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 personalise 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 personalised 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 at any time. Whether an ad that you see is personalised depends on these settings, your cookie settings and if the site that you view personalises ads.
Edit ad privacy settings
- On your device, open Chrome.
- At the top right, select More Settings.
- Select Privacy and security Ad privacy.
- Select the ad feature that you’d like to turn on or off.
To personalise your ad experience, Chrome notes your topics of interests based on the sites that 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 three interests at a time with sites. You can block topics and categories of topics that 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 four weeks.
To block a topic:
- On your device, open Chrome.
- At the top right, select More Settings Privacy and security.
- Select Ad privacy Ad topics.
- Under 'Active topics', select topics to block.
To block a category of topics:
- On your device, open Chrome.
- At the top right, select More Settings Privacy and security.
- Select Ad privacy Ad topics Manage topics.
- Turn off the categories that 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 that 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 Ad privacy.
To help deliver a personalised ad experience, sites can recommend and then store ad suggestions about things that 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 Settings.
- Select Privacy and security Ad privacy Site-suggested ads.
- 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 Ad privacy.
