In the latest WordPress update, a new attribute rel="nooopener" has been added to the hyperlink insertion of articles by default
(In order to be compatible with Firefox, it is generally combined to write rel="nooopener norreferrer")
A friend mentioned that adding this may affect SEO, which will cause spiders to stop grabbing the link,
But there are no such comments on the Internet,
This problem may be caused by the confusion of some children's shoes in understanding the role of noopener and nofollow.
The nofollow tag is a "anti spam link" tag pioneered by Google and widely supported by Baidu, Yahoo and other major search engines. The purpose of quoting the nofollow tag is to instruct search engines not to track (i.e. crawl) any outbound links with the nofollow attribute on the page, so as to reduce the weight of spam links scattered on websites! (From Baidu Encyclopedia)
The unopener is used to restrict sub pages from controlling the parent page through window.opener to solve the cross domain problem of target='_blank '.
So far, the article ends.
