I have a software company, and for my main keyword on Google, I am in spot 10. Right now I am getting about 1 sale a day and 10-15 uniques. I know that if I am in the top 3, I will be getting 5-10, or more sales a day. My competitors have been around for several years, and my site is just about to hit 1 yr. Average PR is 3.2, and I am PR 0. I have been building quality backlinks, have a couple web 2.0 properties, regularly update the site, post every day, have rss feeds submitted, and have awesome onsite SEO. What are your suggestions to get me moving up to the top 10? Link wheels, webs, etc. I've hit a wall, and really need some advice. Thanks.
