Well, content is my business, so I gotta ask “Is that all there is?” I notice only 6 strategy articles. You should add some expert content to your site.
No, I am not selling my services–too busy right now.
There are some excellent content providers here in the forums.
Couple of other suggestions:
1) Internal linking is important also. Most of my pages at gamblingteachers have 2 links to other pages at the site. There is a total of 2000+ internal links at the site.
2) Sign up for Google Webmaster tools. Once verified, you will find out how many of your pages has been indexed by G, total external and internal links and much more.
3) Write a separate article and submit to article directories to promote your site.
Good Luck with your site.
P.S. I agree 6 months is a short span to expect results. Alternatively, I got a PR2 after only 3 months, but that was because I put up over 150 pages of content.
