What is a notification pop-up?

Pop-ups that prompt users to enable website notifications are a common tactic for driving user engagement.

This is a specific type of pop-up that tries to get you to sign up for a site's notifications. These will pop in your browser anytime a site updates with new content, but they may pester you with other notices. These are unnecessary and aren't advisable if you're sharing a computer because you have no control over when these notices appear.
