Starting June 15, Google says it will crack down on sites that interfere with the browser back button, flagging the tactic as a clear spam violation that could knock pages lower in its search rankings. Human reviewers could hand out manual spam penalties, while Google’s automated systems may also demote offenders.
Google’s move is hitting home for site owners, who now have roughly two months to remove code that either keeps users stuck on a page or redirects them when they attempt to leave. The company flagged that these issues often trace back to ad networks or packaged libraries—an alert for publishers, online sellers, and small operators leaning on third-party scripts as the deadline approaches.
Google’s term for back button hijacking covers anything that messes with browser navigation—basically, it prevents users from going straight back to where they started. The upshot: people find themselves stuck, redirected to pages they didn’t choose, forced to view ads or recommendations, or just blocked from leaving the way they expected.
Chris Nelson from Google’s Search Quality team said the move was about putting “user experience” above all else after the company “saw a rise” in the practice. According to Google, this tactic makes users feel manipulated and discourages them from checking out new sites. Google for Developers
Google has now folded the tactic into its malicious-practices policy, the section it uses to flag deceptive actions that mislead users about what to expect. Back button hijacking joins malware and unwanted software as a typical example on Google’s spam-policy page—a shift noted by Search Engine Journal following the April 13 update.
Some search-marketing pros backed the change. Glenn Gabe, an SEO consultant, posted on X that sites pulling the tactic were probably due for a manual action and called it “great news for users.” Search Engine Roundtable later picked up his comments. Search Engine Roundtable
Google is urging website owners to strip out any script that tampers with browser history—specifically, anything that adds or swaps in misleading pages that mess with the back button’s normal path. Sites slapped with a manual action for this can clean up and then submit a reconsideration request via Search Console, Google’s tool suite for site operators.
Still, untangling the problem could get tricky. Google noted that some incidents come from third-party libraries or ad platforms—meaning sites might remain at risk even if their internal teams never touched the problematic code.
In recent years, the company has tightened its search-spam guidelines. March 2024 saw new rules targeting expired-domain abuse, scaled content abuse, and so-called site reputation abuse—where third-party content is published mostly to leverage the ranking power of the host. Publishers got a deadline of May 5 that year to comply with the site-reputation policy.
With this two-month warning, site owners face a mid-June deadline to make sure the back button actually sends users to the last page they visited—and to clean out any ad or library scripts that break that flow. Miss the mark, and Google says your rankings could suffer.
