Hi Lara
Anchors and Links go together. When someone clicks a link they are sent to an Anchor.

Do you mean links?

clickable or anchored what....

Depends what's the purpose?

Clickable, you may want your visitor click and visit another resource.

Anchored, you want folks to shift to a piece of content within the same webpage, for example a table of contents for your post.
