Article Submission Directories That Post Immediately
There are different article submission directory scripts that most of these sites use. The most popular is the Article Dashboard script, mostly because its free to download and easy to set up. However there's a lot of back end work that goes in to maintaining an article directory of this nature, that could result in your articles not getting posted right away.
Because of the nature of the script, article directory owners have to "hand moderate" each and every article that gets submitted to them. This can take some time, especially for those more popular directories that get a lot of article intake every day.
Now this can serve as an advantage for you, because hand moderating means that your article will get approved over time. When you submit to many of these directories then, you're assured that your one article will not show up like its spamming the web, but rather, with various intake levels on these directories, your articles will start showing up in a "staggered" fashion. Which is an "organic" way of seeding the web with your content.
But on the down side, you have to wait. It could take days, weeks, or even months before these hand moderated directories will begin showing your article on their site. With the rapid pace of Internet Marketing, sometimes you want results fast.
So while you're waiting for these directories to post your articles, you could also submit to the article directories that automatically approve and post articles. They generally tend to be the lower end of Page Rank, but they also get the circulation of your article going immediately so you can add some social power behind them.
Here are some that auto approve and post:
Articles Basket
Articles In A Box
Articles For Profit
Article Topic Club
Article Submitter Pro Net
Instant Articles
Limitless Articles
All the above directories will instantly approve and post your articles if they're submitted into the proper category and use relevant keywords and key phrases.
By using them regularly, your articles will begin their life on the web right away, and you'll be giving your article submission a kick start in the right direction.
