My site has been passed a optimization stage; i re-programmed, i've been spend hours reading seo documentation and tried to respect everything.
I started with the HTML code, checked every line and validated it.
I modified the meta tags (description, keyword) and re-adapted them to a specific key-word.
- created a sitemap with a summary to my folders and subfolders
- included CSS to add names and titles to the navigation elements
- created unique articles strictly related to the subject and used the keyword refers to
- verify the keyword density; i take care that word has the biggest apparitions
- submit the site the big directories

Now i did all these i hope my site will grow up in Googles ranks, and get more indexes.

A higher Page Rank doesnt necessarily mean higher rankings.

Page Rank algorithm is completely different from actual ranking algorithm. You should set your priority whether you wish to see more green fluid in your Google Toolbar, or more customers/visitors through higher search engine rankings.
