Google will begin penalizing websites that engage in ‘back button hijacking’—a deceptive practice that disrupts user navigation—by demoting them in search rankings starting June 15, 2026. The tech giant confirmed the move in a recent update to its spam policies, citing user experience as a top priority.
Back button hijacking occurs when websites override standard browser behavior, trapping users in loops or redirecting them to unwanted pages. Analysts estimate that 12-15% of e-commerce and ad-heavy sites currently employ such tactics. ‘This has been a growing complaint for years,’ said a digital marketing analyst familiar with Google’s webmaster communications. ‘The search team finally has detection methods sophisticated enough to enforce penalties at scale.’
Google’s Search Liaison team clarified that first offenses will trigger manual reviews, with repeat violators facing algorithmic demotions. The policy aligns with broader efforts to combat ‘search engine spam,’ which saw major updates in 2025 targeting AI-generated content farms.
Industry observers note the timing coincides with Google’s preparations for antitrust scrutiny in both the EU and U.S., where regulators increasingly focus on manipulative web practices. Some web developers argue the policy could disproportionately affect small businesses relying on third-party platforms with built-in navigation scripts. ‘The enforcement mechanism needs transparency,’ cautioned a web standards advocate at the World Wide Web Consortium.
If effective, the crackdown may accelerate adoption of alternative engagement strategies. Early data from SimilarWeb suggests affected sites are already testing less intrusive retention methods like exit-intent popups.
