What am I doing wrong?

Now my site is ranked page 13 with exact keyword.. But then the cubestat.mydomain blabla is at page 11.. What am i doing wrong? I posted alot of backlinks for my site

How long have you had the site?

It is really impossible to tell what you are doing wrong...two main factors for good rankings is backlinks quality (not quantity) and content. Also do not expect to rank in a few days as a guy before me has mentioned.

Um.... could you be a little more clear on what the problem is, how long you've had the site, what sort of back links you're making, what sort, etc?

I'm all up for helping, but it's pretty hard to tell what help you need from that post, if it's just increasing your ranking, have you tried harvesting your competitors backlinking strategies from Yahoo site explorer?
If you're just starting out I think that might be the strategy for you, it's not the best or most effective, but you'll learn alot from it.

More information, please...
Competition;
Domain age;
Backlinks type/count;
And so on.
