What Is Back Button Hijacking and Could It Be Hurting Your Site?
Google added back button hijacking to its spam policies in June 2025 and began actively enforcing those policies in June 2026, including, many SEOs believe, as part of the June 2026 Spam Update. If your site or a developer working on your site has used this technique, you may have seen a rankings drop and not known why.
Here is what it is, why Google penalizes it, and how to check your site.
What Is Back Button Hijacking?
Back button hijacking is when a website manipulates the browser’s navigation history so that clicking the back button does not take the user where they expect to go.
Normally, if someone finds your site through a Google search and clicks the back button, they return to the search results page. That is the expected behavior, and it is how browsers have always worked.
With back button hijacking, a site uses JavaScript to insert extra entries into the browser history stack. When the user hits back, instead of leaving the site, they get bounced to another page on the same site, dropped into a redirect loop, or presented with an exit-intent page that was not part of their original browsing path. They can feel stuck.
Why Do Sites Do It?
The motivation is usually bounce rate or lead generation. Site owners or marketing agencies reason that if they can keep users on the site a little longer, they might convert. Aggressive e-commerce sites, affiliate marketers, and some SaaS landing pages have used this technique for years.
The problem is that it is deceptive. It overrides the user’s intent. And Google is now treating it as a violation of its spam policies, which means sites using it are at risk of ranking suppression.
How to Check If Your Site Does It
The simplest test is manual. Open your site in a browser, navigate to a few pages, then hit the back button. Do you land where you expected? Try it from a Google search result specifically, so you have a proper referring page in your history. If hitting back keeps you on the site or redirects you somewhere unexpected, that is a signal worth investigating.
On the technical side, the behavior is almost always implemented through history.pushState() or history.replaceState() in JavaScript. A developer can audit the site’s JS for these calls and determine whether they are being used legitimately (for single-page application routing, which is fine) or to manipulate navigation.
Plugins and third-party scripts are common culprits. Exit intent tools, popup builders, and some page builder add-ons have been known to include this behavior. It may be running on your site without you or your original developer ever knowing it was added.
What to Do If You Find It
Remove it. There is no SEO-safe version of back button hijacking. If the behavior exists in a third-party plugin or script, either configure it to disable the history manipulation or replace the tool entirely.
If you saw a traffic or rankings drop during May or June 2026 and have ruled out content quality as a factor, this is one of the next places to look.
The Bigger Picture
Google’s June 2026 Spam Update reinforced a pattern that has been building for several cycles: technical manipulation tactics that prioritize site metrics over user experience are increasingly being caught and penalized at scale. Back button hijacking is one example. Thin AI-generated content is another. The common thread is that Google is getting better at identifying the gap between what a site appears to offer and what it actually delivers.
If you are not sure whether your site is clean on this or other technical spam signals, a technical SEO audit is a good starting point.
