I understand that ezinearticles.com does not accept articlesthat have been submitted elsewhere. Is this true? If it is, would they deny acceptance of an article if you submit it to them, and then post the same article on your blog? If so, how much would you have to "spin" the article to have it be different enough to post it on your blog without being to close to being a duplicate to the one submitted to ezinearticles?
For so far I know as long as you have written the article yourself there would be no problem to get your article accepted even if it's published on your own website (assuming the article is quality). Problems may arise when you submit PLR articles which dozens of other people have also access to. In order to use PLR articles for article submission you better take some time to rewrite them extensively.
I think 30% unique content should be enough for ezinearticles, you don't have to rewrite the whole article.
Or, try submitting the article to Ezine first, and then putting the article on your own website or even other article directories after they approve it. This is what a lot of people do, so it works fairly well I suppose.
Actually I just asked the same question at twitter.com and get answer from ChrisKnight (CEO of ezinearticle). YES, You can.
It does not matter if the article has been published elsewhere. What matters is who wrote the article. If you submit an article saying that you wriote it and they find the same article somewhere else attributed to a different author that is when the problem arises and the article will be rejected
No problems here with that. I use software to submit articles to about 200 directories all at once, one of which is that one. Never had any problems with that at all. Now, keep in mind, I write my own articles and don't just regurgitate those that are already out there on the Internet. Good luck!
