TL;DR
Google now explicitly bans back button hijacking as a malicious practice, risking manual actions or demotions for sites that interfere with browser navigation.
Key points
- 1
What back button hijacking is: Back button hijacking occurs when a site prevents users from returning to the previous page via their browser's back button. Instead, users might be redirected to unfamiliar pages, shown unsolicited ads, or face other disruptions to their browsing flow. This practice breaks the fundamental expectation that clicking back returns to the previous page, creating frustration and a sense of manipulation. For example, a user visiting a news site might be unexpectedly sent to a login page or a third-party ad network after clicking back, which can make them feel tricked and less likely to trust the site in the future.

Why Google is acting: Google has identified a rise in back button hijacking as a deceptive practice that harms user experience by interfering with browser navigation. This behavior violates Google's Search Essentials policy, which prohibits manipulative or deceptive actions that create mismatches between user expectations and outcomes. The policy specifically states that malicious practices lead to negative user experiences, compromised security, or privacy issues. By designating back button hijacking as an explicit violation, Google aims to address the growing trend of sites using this technique to manipulate users, which can result in users feeling manipulated and avoiding the site altogether.
- 3
What site owners must do: Site owners must immediately review their code and configurations to ensure they are not interfering with browser navigation. This includes checking for scripts, libraries, or ad platforms that might redirect users when they click the back button. For instance, if a site uses a JavaScript library that replaces the page after a back button click, it must be disabled or removed. Google recommends thoroughly auditing all technical implementations, particularly those related to user navigation, to eliminate any deceptive practices. If a site has been affected by a manual action, it can submit a reconsideration request in Search Console to restore its search visibility once the issue is resolved.
