Well, this is my first content (article) based website (http://fitnesslifelive.com) I have made and centers around a topic I am very knowledgeable about, health and fitness. All my content is 100% original and has not been indexed my google yet. My question is, if I am going to submit articles to article directories like http://www.goarticles.com/ should I write new articles to point to my website or can use articles that are already written and published on my website? Thanks
