If you add an external link in the template or in the
post and use the target="_blank" attribute, then immediately complete
the rel="noopener" on the links.
When we link other web pages to our blog page using target="_blank" , the new page process that runs in the browser's new window is the same as our page process. If the new page is executing heavy JavaScript, then the performance of our blog pages can also be affected. Oops ... it turned out to be so impactful ...
The target="_blank" attribute on external links
is also vulnerable. The new page has access to the window object through
window.opener , and can direct our page to a different URL using
window.opener.location = newURL .
For that, please fix the external link that uses
target="_blank" on your blog by adding the rel="noopener"
like the following example:
If combined with rel="nofollow" the writing is as follows:
<a href="http://www.domainLain.com/" rel="noopener" target="_blank" title="Domain Lain">Domain Lain</a>If combined with rel="nofollow" the writing is as follows:
<a href="http://www.domainLain.com/" rel="nofollow noopener" target="_blank" title="Domain Lain">Domain Lain</a>May be useful.
