Can anyone give me some ideal?

I am new to seo, my site has 3 monthes, I have done some seo work, but I found there is little traffic for my site, can anyone give me some ideal?
My seo works:
1. I submit to about 400 free directory
2. Submit 4 articles to 7 article website
3. Do signatures in 10 forums
my website: http://www.cn-crystal.com
Any ideal will be appreciate.

Thanks

Do some keyword research and target a less competitive keyword or phrase

Hi,

I have check your site the PR is '0' so keep working directory submissions.

Submit your site to Yahoo & Dmoz directories, do some unique keywords research, bold tags, H1, H2, H3 tags, Meta keyword and description tags, use signatures as you already doing it and wait for the results it will take some more time.

Good luck
