A pop-up is a window or overlay that appears on top of the page you are viewing. It can be a separate browser window or, more commonly today, an element drawn inside the page, such as a newsletter prompt, a cookie notice or a login dialog.
Why it matters
Pop-ups can be useful for notices and quick actions, but they interrupt reading and are a long-standing source of annoyance. Browsers block most unrequested pop-up windows by default and only allow them after a user action such as a click. Search engines may also demote pages whose intrusive overlays cover the main content on mobile devices, and poorly built overlays are hard to close with a keyboard or screen reader.
Example
A site shows a newsletter box after the visitor scrolls about 70 percent of an article, offers a clearly visible close button and does not show it again for 30 days. A fake "Your device is infected" pop-up that cannot be closed and urges a download is a scam, not a real warning.
Common mistakes
- Showing an overlay immediately on arrival, before visitors can see the content.
- Hiding or shrinking the close control.
- Trusting alarming pop-ups that claim a virus or prize. Close the tab and, if needed, restart the browser.
