You can try to optimize your article to google eyes and see if you actually outrank the other articles.
Otherwise, you gotta push it with backlinks.
PS: I'm looking for some good bum\article marketer for jv. If you are good with articles, you write and I'll put your article on google's first page (even for medium or medium-high competitive kws, just a matter of work). Then we cash 50% each.
If any of you BH is interested, pm me please.
