If i submit articles to different sites(articlecity.com etc) which are already on my own website, will it make any duplication problem for me?
I wouldn't risk it if you have a good site because I'm not sure if Google has completely ironed out their issues with finding the authority site in cases of duplicate content. Not totally sure though.
I would play it safe and only submit unique articles. You can also try modifying the original article enough to make it unique.
If your article are unique then don't worry about this. Just let bot crawl them first before submitted to another article directories to prevent supplement results, also prevent from someone copy your article and got indexed first then got your site supplement results too. Submit articles to many articles directories won't hurt you for sure.
it's not a good idea to submit the same article even when duplicate content isn't an issue-- you could very easily be outranked by the sites you submitted to.
Try to make three different copies for the articles. Use the first copy for your site. Second for the top 10 article sites. And the last for all the others.
Yes is does. Just make sure that the content you put on your page is NOT the same as you submit to top 10, and the other directories.
