I hae 4 keywords that I want to target, all are really related. So far I've been targetting those exact 4 keywords exclusively. I am ranked in the 6-9 range for these keywords even though I have better on page, and more quality links than they do. I've checked the competitors links and most of the links dont even include the keywords that they are ranked for and I am targetting. Does my link building look too unnatural. What do I need to do?
