I hope this hasn't already been asked. If so, I couldn't find it. Although I am already listed in yahoo, I am not ranked quite as I would I hope. I feel I have optimised my site quite well and when comparing it against my competitors I cannot see any significant difference (although I don't have as many quality links in). I am wondering if I pay the x amount of dollars per year am I likely to rank higher. Any responce would be much appreaciated.
