Google has launched a new site, CookieChoices.org, to help visitors of European sites learn more about the digital breadcrumbs they leave behind through cookies.
The site includes code that publishers can use to incorporate notifications into their own sites and apps. The notifications could take the form of pop-up alerts or a bar at the top of the screen, ostensibly to give details like the visitor's browsing history or profile information.
People in other countries like the US could see the notifications too, Google said, unless the publisher adds their own geographic restrictions.
Google's new site could give this type of information prime real estate across the wider web. It comes amid a recent European ruling letting Europeans submit "right to be forgotten" requests to have search links to information on them removed.
CookieChoices.org is not focused on Google search results. But if enough sites make use of it, it could improve people's understanding of the massive amount of data collection that goes on behind the scenes of the web.
