You have some good responses to your question here, but maybe I can add some additional information to help you combat how Poems are valued, ranked and scored. (I work for a web development firm and head their online marketing/SEO department, helping their 500+ clients rank on search engines, so I hope this helps you add some value to what he are doing here on HubPages ;-) ).
Poetry as well as creative writing is not considered as "valuable" as other hubs by Hub-pages because they are not considered to contain as valuable of information by Google as other websites and webpages.
Even if your poem addresses a certain issue, such as domestic abuse or marriage- it will more than likely not do as well as an article on the same subject matter unless you can spruce up its value. Google puts more value on sites/webpages that provide beneficial information. Other than a level of entertainment, poetry often lacks this "benefit" and as previously mentioned, lacks the word count recommended as a Google Best Practice. Although you do not need to write 1250 words, the more the better (to increase your chances of being crawled and indexed, your hubs need to have at least a 250-300 word-count).
To help your Poetry Hubs out a little bit, be straight forward and generate titles that contain specific words that could be considered search words related to the subject of the writing.
IE- An Original Poem- Domestic Abuse in America
or Life after Marriage- Prose Poetry
Also, consider writing an explanation or additional content in your poetry hubs that will give it more benefit. This should be done in an separate text capsule, and make sure you take advantage of the option to add a Title to that capsule that is again to the point about the poem and the content that is being added.
IE- Add some facts to the content apart from the poem-
Domestic Abuse in America is on a rise, says a "Statewide Report by ABC Company is Your town, USA.
or include your experience with that subject and why you are writing about it. (but any statistics or facts you can include the better chance the poem has to perform).
When you add images to your hubs, again-use the titles for each capsule to drop in a subject related phrase, use unique images (99 out of 100 times, I use my own original images on my hubs), if you use your own images, be the source and add the URL from your HubPage profile as well as a sentence that relates the poem to the image.
Hope that helps and doesn't confuse
