How to completely block a link from a search engine?

Question

Search Engine Optimization

It is necessary to completely close the link from indexing. so that it does not get into the search results, i.e. the robot completely ignored it. Now I do it like this

<a class="rec-name" href="/company/extremesport/?category=sport" title="ExtremeSport" rel="noopener,nofollow" target="_blank">ExtremeSport</a>

but there is a suspicion that the search engine will read this link

Answer 1

1. Do it with jQuery.
2. Do it through a redirect - link through link.php?url=/category/test/
In general, there is a SEOHide script for closing.
Ps You can do cloaking in general, I have a collected list of current User-agents of search engines (google/yandex/rambler, etc.), write to me.

Answer 2

It looks like the error rel="noopener,nofollow"should be rel="noopener nofollow"without a comma
