Serious SEO Tips/Help?

[widecap963]

For those of you who already have your website fully optimized for search engines, or those who know a lot about search engine optimization: Please help me optimize my website.

I'm not a total noob to SEO, I have my website showing up in google, and some of my keywords provide "alright" google page rankings, others dont. However my website is not fully optimized at all.

I need help, tips, tricks, and ideas on how to better optimize my site.

So far I have submitted my website to local business directories, made sure good keywords are abundant through out my site, and manually submitted my website to multiple search engines..........even so I am not getting the desired results in googles search results Etc.....

Help please Thanks,
Mike
