Now before we proceed any further, let's discuss what duplicate content is, and what it is not.
You've no doubt heard that you should not submit the exact same article to more than one article directory, that you should amend it slightly in some way. This is because Google will supposedly penalize sites with duplicate content, and this is true to some extent, although I think "penalize" is the wrong word. If two or more sites contain the exact same content, then Google will usually only list one of those sites in its organic search results, effectively filtering the other sites out. This poses a problem for someone hoping to get an article listed within Google under a certain keyword phrase.
Our objective on the other hand is not to get our articles listed within Google. Our sole objective is to create backlinks to our main web page by placing a link within our articles. Remember that the contents of our main page will be 100% unique and original and will not be submitted to any website or article directory. Our articles on the other hand will be duplicate content. We couldn't care less whether or not anyone actually visited our articles. For this reason, the so called "duplicate content penalty" doesn't concern us in the slightest when it comes to article submission.
With that being said, we have only one objective in mind when it comes to article submission - Quantity. Quantity. Quantity. The more backlinks we get, the better.
So where do you start in your article submission expedition? I could list a few sites, such as ezinearticles.com, goarticles.com, etc.. however there are literally thousands upon thousands of article directories out there that you can obtain backlinks from. There is no way I could list them all here. So to cut a long story short, submit your article, in its unaltereted state, to as many article directories that you can find. Don't worry about editing it for each new site.
Now you may think this to be a little absurd, perhaps even spammy, however the truth is quite the contrary. Article directories love informative, original articles, even if they've been sent to a thousand different sites. The only thing they ask is that you created the content yourself, and that the author name corresponds to the name you use on the article directory site. For this reason I recommend using a generic author name on all the article directories that you submit your articles to.
Article Marketer -
If you don't have the time to manually submit your article to hundreds of individual article directories, I highly recommend that you use a service known as Article Marketer (no affiliate link). Article Marketer will automatically submit your articles to over 1000 article directories. Each article is reviewed by a real person to ensure that it meets submission guidelines of all the article directories before it is submitted. This site is truly worth its weight in gold, and I honestly wouldn't be marketing with articles right now if it didn't exist. It can literally save a month's worth of work in a few minutes.
Normally articles take about a day to be reviewed before they're submitted, however it's not uncommon for this process to take a couple of days at times due to staffing shortages. There is also a free submission service at the website, which works similar to the paid submission service, however these articles can take up to a few weeks before they're reviewed. The thing that I like most about the service is that there is no limit to how many articles you can submit. I recommend Article Marketer to anyone who plans on using the techniques taught within this tutorial in order to create a vast amount of relevant backlinks.

Important: Don't submit duplicate content to the same article directories -
Whilst we don't care whether Google views our content as being duplicate, we do care if the article directories do. The vast majority of article directories only want original content, and if you start resubmitting the same article again and again to the same directory, with only minor changes, then you risk getting yourself banned.
As a general rule of thumb, I recommend that you create a fresh, 100% original article each time you submit an article to the same article directory. So after you've gone on your great article submission campaign, sit down and write a new article targeting a new keyword phrase that is relevant to your web page, and repeat the submission process again. Article directories will begin to love you if you continue to submit informative and useful articles to them.
Spread our your article submission over time -
Submitting articles containing your web page link to a thousand directories at once isn't a problem, but don't spam your web page link endlessly. For every one thousand articles submissions, you can expect to get anything between 30 - 60 backlinks fairly quickly. This is quite natural. If however Google starts to see that you're getting 500 backlinks after you've submitted your article 10,000 times, in the space of just a week, then Google will start to think that something's not quite right, and you may risk getting your site sandboxed for longer than normal, or perhaps blacklisted in exceptionally bad circumstances.
The longer your site has been around, the more backlinks Google will consider to be normal. So if you can, submit a new article to a thousand article directories once every week, over a period of 6 months. This will provide a natural looking backlink progression.
