Starting June 15, Google plans to crack down on sites that mess with the browser’s back button. Pages using this trick will risk getting hit with spam penalties, either through manual action or automated drops in Search ranking. It’s the first time Google has called back-button hijacking a direct spam violation.
This switch is significant: Google, after years of warnings, now has a hard deadline for cracking down. Site owners using third-party libraries or ad-tech that interfere with users who try to leave a page are on notice—it doesn’t matter if the behavior is hidden inside bundled tools or ad platforms, Google says the responsibility is still theirs.
Back-button hijacking happens when a website tampers with your browser history, stopping the back button from taking you to your last page. Instead, you might get rerouted to unfamiliar pages, hit with unwanted ads or suggestions, or even find yourself stuck, unable to exit the usual way. Google has now folded this into its malicious practices policy—a spam rule targeting deceptive or harmful behavior.
Chris Nelson from Google’s Search Quality team said in an April 13 post that users sometimes feel “manipulated” and get turned off from exploring new websites, a trend Google says has become more common. Nelson urged site operators to get rid of or switch off any script that sneaks fake pages into browser history, and to check their code, imports, and settings related to third-party tools.

Google flagged that both manual spam actions—those penalties handed down by human reviewers—and automated demotions can result from violations. According to Search Console documentation, manual actions might push certain pages or even whole sites down in rankings, or take them out of search altogether. Site owners do get a shot at a review by Google if they address the issues.
Google has flagged this trick for years. Back in 2013, a Search Central post warned that sites slipping extra pages into users’ browsing histories risked getting booted for deceptive practices. The change coming in April 2026 doesn’t introduce a new policy—it just puts the existing rule in clearer terms.
This isn’t tied to Google’s March 2026 spam update. That update, according to the Search Status Dashboard, wrapped up on March 25—just under three weeks ahead of Monday’s policy shift.
Glenn Gabe, an SEO consultant at G-Squared Interactive who covered the tactic last year, described the move as “great news for users” in a LinkedIn post. He pointed out that certain sites relied on a “Google-like feed of articles” to mislead visitors into lingering. LinkedIn
But the crackdown could get messy. Google admits some back-button hijacking traces back to third-party libraries or ad platforms—so even sites unaware of the practice might get flagged, unless they track down and scrub the problematic code ahead of June 15.
