Your site has very few good links with keywords in the anchor text of the links. What your site needs is proper On page Optimization and Off-Page Optimization with Directory Submissions, Article Writing and Submissions, Blog Posts and commenting, Forum posts and commenting, Link Exchange, and One-Way links, etc, to rank for keywords.

PR is not everything for ranking for keywords.

Seems to me you are wasting your time posting repetitively.

Concentrate on building your web site. Make your content outstanding in comparison with your keyphrase competitors. The search engine will come around to liking what you have created and will eventually reward you for your web content's uniqueness and authoritativeness.

Naturally evolve. Don't listen to the short-cut takers whose advice will only provide temporary spikes. Get to the top and stay at the top!

Well I did have some luck I got one of my sites to the first two pages for what I wanted however when I created the sites I put the keywords in the url. Worked like a charm but the site that does not have the keywords in it I have found to be a problem. So that site I am going to turn over to a company to have it professionally done as I have tried everything and give up! That site getting to the top is not the problem Id be happy get listed under the right keyword ha ha,AND YES MY TAGS AND CONTENT ARE FULL OF THAT KEYWORD
