One of the advantages of the web is that it allows developers to create any type of experience they can imagine, which has led to the rich diversity of content available on the web today. While most content producers are interested in providing excellent experiences for their users, there is a small number that uses the flexibility and power of the web to take advantage of users and redirect them to unintended destinations.
1 out of every 5 feedback reports from Chrome users on desktop mention encountering some type of unwanted content. Following on from features like Chrome's pop-up blocker and autoplay protections, over the next few releases Google will be rolling out three new protections designed to give users all the web has to offer, but without many of these types of unwanted behaviors.
One piece of feedback is that a page will unexpectedly navigate to a new page, for seemingly no reason. This redirect often comes from third-party content embedded in the page, and the page author didn't intend the redirect to happen at all. To address this, in Chrome 64 all redirects originating from third-party iframes will show an infobar instead of redirecting, unless the user had been interacting with that frame. This will keep the user on the page they were reading, and prevent those surprising redirects.
When the user interacts with content, things can also go wrong. One example that causes user frustration is when clicking a link opens the desired destination in a new tab, while the main window navigates to a different, unwanted page. This is effectively a circumvention of Chrome's pop-up blocker, one of users' favorite features. Starting in Chrome 65 the browser will also detect this behavior, trigger an infobar, and prevent the main tab from being redirected. This allows the user to continue directly to their intended destination, while also preserving the context of the page they came from.
Finally, there are several other types of abusive experiences that send users to unintended destinations but are hard to automatically detect. These include links to third-party websites disguised as play buttons or other site controls, or transparent overlays on websites that capture all clicks and open new tabs or windows.
Similar to how Google Safe Browsing protects users from malicious content, starting in early January Chrome's pop-up blocker will prevent sites with these types of abusive experiences from opening new windows or tabs. To help site owners prepare for this change, today we're also launching the Abusive Experiences Report alongside other similar reports in the Google Search Console. Site owners can use the report to see if any of these abusive experiences have been found on their site and improve their user experience. Otherwise, abusive experiences left unaddressed for 30 days will trigger the prevention of new windows and tabs.
Together, these protections will dramatically improve users' web browsing experiences while still allowing them access to all that the web has to offer.
