Google Search to classify 'back button hijacking' as spam
https://9to5google.com/2026/04/13/google-search-back-button-hijacking/
This is a news summary.
According to Google's new spam prevention policy, websites that engage in so-called 'back button hijacking' will be less visible in Google search results.
Back button hijacking refers to a website interfering with users' ability to immediately return to the previous page by pressing the 'back button'. This means users are forced to navigate to pages they never visited, or are exposed to unwanted advertisements or recommendations, disrupting their normal web experience.
Google is giving site owners two months to fix the issue, including checking advertising platforms. The enforcement begins June 15, 2026.
Excerpt from Google's announcement (English)
"If you are currently using scripts or techniques that prevent users from immediately returning to the page they previously visited by using the back button, or that insert or replace deceptive and manipulated pages in the browser history, you must remove or disable them."
"In particular, some instances of back button hijacking may originate from libraries or ad platforms included on the site. Site owners are advised to thoroughly review their technical implementation and remove or disable all code, imports, or configurations that cause back button hijacking to ensure a beneficial and non-deceptive experience for users."
