Google Search Warns Sites to Fix Back-Button Hijacking by June 15 or Risk Ranking Penalties
Google will start penalizing websites that hijack users’ browser back buttons on June 15, treating the practice as a spam violation that can lower search rankings. Sites using the tactic may face manual or automated penalties, even if the behavior comes from third-party code or ads. Google said site owners are responsible for removing deceptive scripts before enforcement begins.
