Submitting same article to multiple article directories

[C.Rebecca]

See, articles are taking a backseat when it comes to influence your SERP rankings or marketing.

After Panda update article directories lost their dominance on search results, though many of them are catching up again.

Instead, you can try with blogging... It is far more effective technique than article submission / marketing.

I never suggest you to submit same article in different article sites. You have to write a unique article for a particular site.
Article submission is really helpful in getting high rank, if you use keywords in title and in content of article.

i will suggest you to put the article as a guest post at some high PR site it will give you more advantage rather than spammy spun articles marketing.
