In Chrome, open Settings > Privacy and security > Site settings > Notifications, then choose the default permission or block a specific site. This changes website notifications, not Windows notifications for every app.
1
Decide whether to block one site or every site
Before changing permissions, decide whether every website or only one noisy site should be affected. Note any sites whose calendar, messaging, delivery, or security alerts you still need.
2
Open Chrome notification settings
Open Chrome, select More, then Settings > Privacy and security > Site settings > Notifications.
3
Choose the default behaviour
Select the notification option that blocks sites or asks before a site can send notifications.
4
Block an individual site when needed
Under a site permission list, remove or block only the site you no longer want to notify you.
Reload a previously blocked test site and inspect its site-information control. Confirm Chrome no longer offers notifications while notification permissions for unrelated trusted sites remain unchanged.
6
Keep Chrome and Windows notification controls separate
Blocking website notifications does not disable Chrome or other app notifications in Windows. Use Windows notification settings separately only when the operating-system banner itself is the unwanted layer.
7
Restore alerts for a trusted site
If a trusted site needs alerts again, return to Site settings > Notifications, remove its Block entry or change its permission, then reload the page and respond deliberately to the prompt.
Video walkthrough
If it does not work
If notifications continue, identify the site name shown on the banner and check both its Chrome permission and Windows' Chrome notification permission. Remove suspicious site permissions instead of installing a notification-blocking extension with access to browsing data.
