How to hide links from indexing?

Question

HTML

I know two ways:
1) Standard - noindex and nofollow attribute. As far as I know not working.
2) On JS/jQuery - change the span link tag, substitute the wrong URL, and so on.
Which way do you use?

Answer 1

атрибут rel="nofollow"
Googlebot will not follow the link with this attribute, but share the PR with the donor site.
And the myths about the non-working noindex tag were related to the problem of validating pages using this tag. Yandex found a way out and the correct use of the tag is now:
<!--noindex--> Ссылка <!--/noindex-->
