: What is the difference between "nofollow noopener" vs. just "nofollow"? I use the WordPress plugin Ultimate Nofollow to easily make links as nofollow. So I expected that plugin will add rel="nofollow".

Nofollow will give you granular control to individual external links such as a webpage you don’t necessarily endorse or an internal link you want to prevent bots to access or index such as your members login page.

Noopener is another property that gives you granular control for webpage performance and security when accessing content on a new window, the noopener directive will block access to window.opener.

read google explanation here and read here why is helping your webpage to become more secure.

In terms of SEO, what really matters is how you use the nofollow rather than the noopener. Noopener is just preventing the browser (some of then) to execute malicious Scripts.
