Do one thing create one page for ecah iterm and while submitting articles change the link part in each article directory
If you are writing original contents then it is good for link building but not for traffic. You can use the way zelgly2 said
It is not good for seo to post same article to many directories. You must have different articles! But in this case will be beter if you post them in 5-10 trusted directories.
The thing that you do is normally done by almost all article submitter. There is huge list of article site list and to generate article through spinners is not at all preferable to use for generating different article.
Generate text with different anchor for links will give a better effect than simply sending the same article!
Its not good to submit the same article in different directories. There are no use in that and there is a chance of article not getting posted as its not original.
i think you can use one single article to 5 - 10 article submissions. Or else you can spin the article and submit to some more directories.
don't submit your same article to all of directories site, in my experience it's not good. the good ways is use different content/not duplicate, create multiple post,, you can use spinner soft and then submit your article to directory site.
Submitting the same article to the multiple article directories results in the content duplication. Put the article in your blog or site and submit to few top article directories. Try to rephrase the article and title and submit it to few more article directories.
