Noopener Definition & Meaning

What Is Noopener?

Noopener is an HTML attribute (rel=” noopener”) that can be added to external links set to open in a new browser tab or window that works as a security measure to prevent malicious links from gaining access to a user’s browser through the original page.

The noopener attribute adds an extra protection layer by stopping a website through which a link is acquired from using the window object to control a browser tab.

Excluding a noopener from the URL makes a website vulnerable to phishing and malware attacks.

Pages on WordPress websites have the noopener attribute added to external links by default, and removing it requires altering the theme’s files. Noopener attributes don’t affect a page’s position in the search rankings or influence affiliate links in any way.
