Can some one elaborate to me about article submission. Is it better to submit lot of articles to one good article directory, like ezinearticles, or spend time only submitting a few to every article directory you can find. Does each new backlink that you gain from a big directory like EzineArticles matter that much, or is it just the first backlink that is the most powerful? Is it worth it to keep submitting after you've done like ten? I'll always submit to EzineArticles no matter what, but I'm just wondering, after a fair amount of article submission, do you still get SEO from the backlinks?
