Is it beneficial to leave a link on the comments ⁉️🤔

I have noticed some users leave out a link in the comments section which has nothing to do with the posts, does this type of commenting increase the chances of posts referenced in the link to be opened?
Is there any advantage of leaving a post link in a comment?
Metabbs is about support so why leave a link since everyone in metaBBS understand the support system in place.
