Google is dropping the back button trigger for AdSense vignette ads on June 15, 2026 due to the new Google search penalty for back button hijacking. Google wrote, “Starting June 15, 2026, the browser back button will no longer trigger a vignette ad.”
What is changing. Google explained that the back button trigger will no longer work after June 15th. The “change will apply automatically for all publishers who have opted in to “Allow additional triggers for vignette ads” and will take effect across all supported browsers (including Chrome, Edge, and Opera).” Google added.
A Google spokesperson told me these same updates will apply to Ad Manager as well.
Why the change. Google explained that the Google Search team “recently introduced a new policy against “back button hijacking” — a practice where websites or scripts interfere with a user’s ability to navigate back to their previous page. To ensure our publishers remain compliant with these latest user experience and search quality guidelines, we are removing the trigger that shows a vignette ad when the user navigates backward from the suite of vignette ad triggers.”
This comes after the search community called this out to Google and Google is making the right change here. Of course, some publishers will not be happy because that trigger may have earned them a lot of money.
Why we care. If you currently have the allow additional triggers for vignette ads setting on with AdSense, keep in mind, one of the triggers, the back button trigger, will be disabled on June 15th. It may impact your earnings, but it will ensure that your site does not get penalized by the back button hijacking penalty.
