There are three ways you can go about this. First is manual and gives the best results. You know what the feedback is and this creates detailed profiles that double the links back to your site. Second is by software which does pretty good , however you still have to track which ones succeeded or were declined and they are not very good at managing profiles. An empty profile tells readers your not very accessible. Third is by automated submission services which does all the work of finding and submitting your articles to many locations. The biggest drawback is the lack of feedback and the ability to track the results. Marketers have high need for achievement and require immediate feedback especially if you want to succeed in your advertising or marketing format. I suggest you do not use spinners. They generate in-congruent insults to intelligence. I suggest you do not write about one topic and link to unrelated sites. I suggest you do not use short url services. Think about it, just which domain are you promoting. Redirect links are highly mistrusted. I hard wire short url's into my directory so that my authors have their own short url and get direct links back to their articles which has a proven higher response rate. Writing articles gains you exposure. The results of that exposure is directly related to how well you think out what the reader actually sees. Write so they can interpret information in their own way. Just the facts, not personal opinions. As I have done here, I suggest as its not my choice what you choose , that would be yours only. Wishing you well , tips hat.
