How do I promote other people's stories?

So I've been going around and suggesting roles as you do but I've been wondering: how do I promote someone else's stories (or stories just in general)? Aside from intrusively commenting on other stories' comment sections to go check them out, how do I promote stories that are rather obscure?

And also this unrelated but can somebody answer the last person (Ionniecontreras)'s question?

for example you should check out my stories tbh
