An article should be as highly relevant for the keyword relation as possible.
I simply target every article as information on that given keyword niche. If it is related, the article directory will be way less likely to delete it. IF you do it tactfully, you can have articles stay on for years.
The point is that you have to make them have an information purpose, not just throw crap up there. Article directories are getting just as severe as the search engines and blog directories about the content posted.
Practice the rule of thumb for using real content from the get go, even if it is a spun article on the subject, as long as it is relevant to the keyword's niche market, you are set.
As far as density of content, if you target your article for that niche and use relevant and related material on the subject and not just through crap up there, you can spin it and use it over and over for other relevant keywords in the same niche to gain a higher pull.
The density is a given if the content is focused. No way around it. You don't have to write many nor spend hours on it, just make sure it is on point.
first off sorry for the real noob question
so say i rewrite an article and compare my version with the original on dupecop...what is the minimum % uniqueness enough to bypass the duplicate content filter?
on one of my articles i got a 51.7% uniqueness...so is that good? or should i aim for more?
