How to Publish Poetry Online

Writers and publishers of poetry should first be readers of poetry.  You should read all the best poetry you can, from contemporary, moderns, historical, and even ancients poets.  Read the best and the very best.  Learn how to write in all the poetic forms  that interest you.  Read and write.  Know that "free verse" has to be well-crafted, poetic, rhythmical.

As for publishing, and especially if you're a beginner, there are numerous online opportunites for publishing your poetry.  At http://www.poetrypoem.com, you can a "get a free website to publish a poem or all your poetry."  You can also publish poetry at http://www.FanStory.com.  Also, publish your poetry at web content providers that offer the opportunity for publishing poetry. Many of these also allow for the syndication of your poetry online.

If you're interested in publishing offline and in print, try first some of the local literary magazines and journals.  Get poetry books and journals from your local library, jot down the names of the publishers, jot down the submissions guidelines.  Get a copy of Poet's Market from Writers Digest Books, which contains 1700 publishers of poetry.  Note the markets that are receptive to beginning poets.  Some of these might offer only publication, pay in copies, but if you are a beginner you must build a "resume" of first publications.
