Read the Huffington Post: This sounds so basic and simple but many people who have asked me how to become a Huffpo blogger have never done this. You need to understand the style of writing that works on the website and get to know what type of subject garners the most attention. Look for posts that have many comments, shares and likes in your specific area of interest.
Get to know the verticals: The Huffington Post is comprised of a multitude of special interest sections called verticals. Each of these verticals publishes content that is targeted to a specific demographic or interest. You'll find these verticals listed under the masthead. Examples include Religion, Gay Voices, Post50, Politics, Comedy and Sports. The list goes on and on. On one occasion I had a blog post published in Gay Voices, Religion, Comedy and Politics all at the same time. This may be more of a statement about our current state of affairs than it is about how The Huffington Post is organized. The key here is that you have a voice that will resonate in a specific vertical. Find it.
Get to know the editor of the vertical: Once you find the vertical that you would like to write for (You can write for any vertical, once the first post has been published), find out who the editor is. You can do this several ways. Many times the editor will have a blog post published on the vertical, or you can search for the vertical name and the word "editor" in the search the bar. Or you can click on this link: Editors
Write your post: Once you have the previous steps complete, craft a post that falls somewhere between 500-700 words. Make it current, crisp and unique. While the Huffington Post employs editors, they do not have much time to perform significant editing on a piece. It should be free of spelling errors and grammatically correct. My first piece published was a post about my father, and it was submitted three days before Father's Day. Tie your piece to current events.
Email a link to the editor: Remember the step "Get to know the editor?" You are going to submit a link to him/her and not to the general submission box. I'm pretty sure that is just a waste basket. The email address for the editor will not be listed in plain sight. This is where you will need to perform some sleuthing. Maybe it is in a post the editor wrote, or on another site, maybe on Twitter. You have the name; you can find the email address. If you have a personal blog, post your piece there and then email a link of your post to the editor with a quick message, something like:
