Since KW density has become a non factor with Google.....( except too much)
A natural sounding article should get the job done...KW in the title...
And then relevant content....
Don't know for sure...but have to think that the major article sites are following big G recommendations to maintain their high SE page rank...
Would have to believe that staying caught up on
SEO would help with any content that is produced for use on the net....
