It really depends on your end goal here at hubpages. Are you here to create a writing portfolio and gain some followers of your work or are you here to make money?
If you're trying to gain a following of people who love your poems, then this is a fine place to be (at that point I would strongly recommend linking your poems together if you aren't already).
If you looking to make money then the traffic you're looking to attract is coming from Google. Think "What would I have to search to find this poem?" vs "What would I have to search to find this article?"
Informative articles are going to be more highly searched than poems are. You should also consider the fact that there are so many poetry websites featuring famous poets. If someone searches "friendship poems" they're going to be taken to one of those sites and they likely won't make it far enough along in the Google search to find your poem about friendship.
