A website alert keeps appearing on your computer, but you still want reminders from your calendar or work apps. Start with the website that sent the alert instead of switching off every notification.
This guide covers Chrome on a computer. It follows Google’s current support instructions, checked on September 24, 2026. It is a documentation-based guide, not a device test or a claim that every unwanted alert has the same cause.
First, identify what is interrupting you
| What you see | Where to start |
|---|---|
| An alert attributed to a website through Chrome | That website’s notification permission |
| A new browser window or tab opening unexpectedly | Chrome’s pop-up and redirect controls |
| A message inside a webpage | Identify the page and the message; do not assume it is a Chrome notification |
The distinction matters: Google’s pop-up troubleshooting guide explains that website notifications can continue even when pop-ups are blocked.
Block the unwanted website’s notifications
- In Chrome, open the three-dot menu and choose Settings.
- Navigate through Privacy and security, then Site settings, and open Notifications.
- Find the section for websites that cannot send notifications. Use its Add control.
- Enter the unwanted website’s address and confirm.
Check the sender’s domain carefully before adding it. For example, a calendar service and an unrelated promotional website should not be treated as one sender simply because both alerts arrive through Chrome.
Google also documents a site-specific route: open the website, select the site-information control beside its address, and set its notification permission to blocked. Use the settings route above when you would rather manage permissions without revisiting the sender.
Keep useful alerts and reduce permission prompts
Review permissions individually so the sites you rely on can remain allowed. If the interruption is the request for permission itself, Chrome offers a quieter prompt setting. This changes how sites ask; it is different from blocking a particular sender.
For the current labels and available options, consult Google’s notification instructions for computers.
If a new window still opens
Return to Site settings and inspect the pop-up and redirect section. Google provides separate controls for exceptions there. Changing notification permissions alone is not a complete pop-up fix. On a work or school device, an administrator may control these settings.
A small checklist before you finish
- Record which domain you changed, so you can recognise it later.
- Keep a note of any useful service whose alerts you still expect.
- If another interruption appears, note its sender and whether it was an alert, webpage message or new window before changing another setting.
This is a targeted permission check, not a malware diagnosis. Avoid changing several unrelated settings at once: you want to know which change addressed the problem.
