1. Your site need original content with adequate keywords. But do not spam them otherwise you will even decrease your position.
2. And much harder think is to get back links to your site. You have to find web sites which are relevant to yours and try to get your link on that site, or post on relevant forum and also submit to good PR directories.
This all should help to get higher in search engines and get more visitors to your site.
what's the link to your blog and forum? why not place it in your siggie? :)
Share the site with your friends and forums for them to share with others, submit to directories, social bookmarking sites, do seo...
The link doesn't work -- its apparently restricted for some reason.
This link to youtube video should work, I like this video as concept of word of mouth marketing is demonstrated in simple terms here and it's true that trusted endorsements by friends is the best form of advertising.
