Dawn Anderson asked Google’s John Mueller if using the noreferrer or noopener attributes can hurt your Google rankings and SEO. The answer John responded with was “nope.” So there you have it, feel free to use those attributes without worry.

A Noreferrer specifies that the browser should not send a HTTP referrer header if the user follows the hyperlink.
A Noopener instructs the browser not to send referer information along with header. Technically, it just nullify the object window.opener.
Both do not impact Google, so feel free to use it.
