Article Marketing - what’s your experience??

What has been your experience with article marketing? I have a stable of articles - well over 100 of them from my online networking the last 3.5 years - a few of which I`ve posted on article warehouse sites or article directories. While a couple articles have actually come up pretty high on the Google rankings - #7 - the question is - does it translate into sales?I don`t know. It`s not expensive - but it IS time consuming. I`m about to get some of these articles out in a larger way by hiring a person who does article submissions to sites - but before I hit the "go" button I`d like to know what tangible results others have gotten from article marketing submissions.Oh, one of the other things I`m reading is that the article sites like ContentDesk.com and ArticleCity.com are not that helpful. Far better to go to sites that are targeted to the interests of your ideal customer - for me that would be women home-based and small business owners.Thanks in advance for your thoughts and experiences.All the best,Denise MichaelsAuthor, "Testosterone-Free Marketing"
