Google Updates Their Spam Policies To Include Back Button Hijacking

If you’ve ever clicked the browser back button whilst on a website and ended up somewhere you didn’t expect (a page you’ve never visited, an ad you didn’t ask for, or simply finding yourself trapped on the same page) you’ve encountered back button hijacking.

It has always been frowned upon, but with more websites using this deceptive technique, Google has had enough! As of June 15, 2026, sites that engage in this practice will face real consequences in search rankings.

Here’s what you need to know, and what to do about it before the deadline.

What Is Back Button Hijacking?

When a user hits the back button in their browser, they have one expectation, which is to go back to where they just came from. Back button hijacking breaks that expectation. It happens when a website manipulates the browser’s history, to redirect users somewhere other than their previous page.

In practice, this looks like:

• Being sent to a page you’ve never actually visited.
• Seeing an unexpected ad or ‘recommended content’ overlay when trying to leave a site.
• Having to click back multiple times just to escape a page.
• Being redirected to a completely different site.
• Being stuck on the page, with the back button not doing anything.

It’s a technique historically associated with aggressive ad monetisation, affiliate sites, and low-quality content mills. Google’s Chris Nelson from the Search Quality team put it plainly:

“People report feeling manipulated and less willing to visit unfamiliar sites.”

What Google Has Actually Changed

On 13th April 2026, Google officially added back button hijacking to its spam policies as an explicit violation under the ‘malicious practices’ category. The same category that covers malware distribution and unwanted software installation. That’s serious company to be among.

This matters for a few reasons:

1. It was already against the rules, but now it’s enforced. Google have long discouraged deceptive navigation practices, as this Search Central post from 2013 shows, but by adding it as a new spam policy and naming it explicitly, Google removes all ambiguity. If your site does this, it’s a violation, full stop.
2. The penalties are significant. Pages found to be in breach can receive manual spam actions or automated ranking demotions. A manual action from Google is one of the most difficult penalties to recover from, it requires fixing the issue, filing a reconsideration request, and waiting weeks or months for a review. Even after that, regaining your previous rankings could take years.

You have until 15 June 2026. Google has given site owners a two-month window to find and fix the issue. That’s a tight timeline for larger or more complex websites, so if you have been using this practice, it is time to act!

The Third-Party Problem

Here’s the part that catches a lot of site owners off guard, you can be held responsible for back button hijacking even if you didn’t write the code yourself.

Google has been explicit that the policy applies even when the offending behaviour originates from:

• Advertising platforms – ad scripts injecting history states to keep users on pages longer.
• Content recommendation widgets – those ‘you might also like’ plugins that push users into a content loop.
• Third-party engagement tools – widgets, pop-up libraries, and exit-intent scripts.
• Included libraries – sometimes even well-known npm packages or legacy code can contain this behaviour.

As the site owner, the responsibility sits with you. You need to know what’s running on your pages.

How To Check If Your Site Is Affected

This is something we’d recommend doing right now, before June 15. Here’s a practical checklist:

Manual testing

• Open your website in Chrome and navigate into a few pages.
• Press the back button. Do you land where you expect?
• Try this across pages that have ads, pop-ups, or content widgets.
• If you need to press back more than once to leave a page, that’s a red flag.

Technical audit

• Open Chrome DevTools → Sources → Event Listeners and look for popstate event listeners.
• Review any JavaScript that interacts with history.pushState or history.replaceState.
• Audit your ad platform integrations and content recommendation scripts.
• Check your exit-intent pop-up or modal plugins.

Single Page Applications (SPAs)

If your site is built in React, Vue, Angular, or another SPA framework, take extra care. SPAs legitimately use the History API for client-side routing, but the distinction Google is drawing is between functional navigation and deceptive navigation. Legitimate routing is fine, but deliberately trapping users is not.

What To Do If You Find an Issue

First-party code – If your own scripts are manipulating the back button in a deceptive way, remove or disable that functionality before June 15th.

Third-party scripts – Identify which plugin, ad network, or library is responsible and either remove it, replace it with a compliant alternative, or contact the provider. If an ad platform is the culprit, check their documentation for updated configurations or reach out to their support team.

Document everything – If you do make changes, keep a record. If a penalty does arrive, you’ll want to be able to demonstrate that you identified and resolved the issue.

The Bigger Picture

This update doesn’t exist in isolation. It follows the March 2026 spam update and a series of policy tightening moves over the past two years, including crackdowns on expired domain abuse, scaled content abuse, and site reputation abuse.

The consistent thread running through all of these updates is Google’s focus on user experience as a ranking signal.

Back button hijacking corrupts an important signal that can aid in determining if a page meets a user’s query and intent, which is whether they dwell on the page, or quickly return to search results. When users can’t navigate normally, those signals become meaningless, and Google knows it.

The message from Google is clear. If your site prioritises short-term engagement tricks over genuine user experience, expect consequences.
