What are the advantages of publishing ezine articles?

Ezine articles are published for free if accepted by the editor. There's nothing like free publicity that works. One of the main reasons that people subscribe to ezines is because they want to hear what experts have to say about the subject that the ezine addresses. If your article is published, that means you have instant credibility, you are now an expert in your field. People want to hear what you have to say on that particular subject. Editors will not publish articles that are uninformative, though I have seen some weak stuff at times. Another advantage about your article is that it's usually the main feature of the newsletter, in a prime position and noticed by all subscribers. Sometimes there are several feature articles published. Surrounding the article are ads, tips, links and editorial comment.
