• Don't use target="_blank" because that forces only one behavior, opening in a new tab. I should expect the user to open a link in a new tab if he wants to.
• Don't omit the referrer, which is done by including rel="noreferrer". I want other sites to know who is linking to them, in the hopes of getting cross-traffic.
• Do include rel="noopener" to protect users (reference 1).
