Google Will Demote Sites That Trap the Back Button
Google is turning back-button hijacking into a search-ranking problem. Sites that manipulate browser history can lose organic traffic through manual spam actions or automated demotions, and patching the visible page does not undo the trust hit once Google classifies the behavior as malicious.
Google says enforcement starts June 15, 2026, and the policy now explicitly covers pages that interfere with browser navigation or insert deceptive pages into history. The affected surface is Google Search, and the risk extends to sites using history-manipulation scripts, ad tech, or third-party widgets that alter the user’s return path.
The practical risk is lasting visibility loss, not just a temporary policy warning. For traffic-dependent sites, a spam action can outlive the offending code and keep suppressing search performance after the user-facing issue is fixed.
