What changes is that Google is now naming this practice explicitly in its spam policies. According to a Search Central update published on April 13, Google is making back button hijacking an explicit violation under its malicious practices policy.
The company describes the issue as a discrepancy between what the user expected from the website and what the page provides. Rather than going back to the previous page, users may be sent to pages they never visited before or shown unsolicited ads or recommendations.
Why This Matters Beyond UX
Google frames the change as more than a UX issue. It says deceptive history manipulation was already against Search Essentials, but is now being named explicitly in its spam policies. That moves the focus from design abuse into the enforcement area. As soon as a practice becomes explicit within the spam guidelines, it can become a compliance barrier for publishers and affiliates.
Additionally, Google indicated that the issue is not limited to code written directly by the site owner. The company suggested that certain cases could arise out of libraries or advertising platforms, broadening the scope of people whose stack will now need to be audited. This suggests that websites cannot blame third-party code if it manipulates browser history to mislead users.
The June Deadline Puts Technical Teams on Notice
Enforcement will take place on June 15, 2026. Google is giving site owners about two months to make changes before enforcement begins. As for the directive itself, it could not be more clear-cut: disable any functionality that inserts deceptive history entries or prevents users from going back to the page they came from. Should a site receive a manual action for this issue and then fix it, reconsideration is still an option.
Now there’s a definite deadline and a definite risk for engineering, SEO, ad ops, and product teams. Even sites that have never intentionally used such strategies might still be at risk because of embedded ad technology or monetization tools.
This is what search enforcement will increasingly become about – the way pages behave after a visitor gets there. If retaining visitors requires breaking basic browser behavior, Google is now treating that behavior as a spam-policy issue.
