Google will start penalizing “back button hijacking” with new spam policy in June 2026

Google is revamping its spam policies to address “back button hijacking”, a deceptive tactic that interferes with browser navigation. This practice will soon become an explicit violation classified under malicious practices in Google’s spam policies. Website owners who engage in back button hijacking now face more direct risks, as Google will apply both manual spam actions and automated demotions. These penalties can significantly reduce a site's visibility and performance on Google Search.

While the change focuses on webmaster compliance, it stems from broader user concerns. Back button hijacking disrupts expected browser behavior by preventing users from returning to their previous page, sometimes redirecting them to unfamiliar websites or showing unwanted recommendations and advertisements. This manipulation not only breaks user trust but also creates frustration, with some users reporting they are less inclined to visit unfamiliar sites after such experiences.

To allow webmasters adequate time to adapt, Google has published this policy update two months in advance. Enforcement begins on June 15, 2026, giving site operators a clear window to review and update their practices before penalties are applied.
