I started to study keyword density now, it might help improve my ranking.
Take a look at this article

There are a few catagories the author has shared tips on

• First 25 words
• Hx (heading tags)
• Anchor Text
• Bold and Underlined
• Last Paragraph
• Keyword Weight
• Keyword Density

I will try to practise more and do something on it.

SEO Review - June 2005

I plan to do a review to talk about the SEO practices i have done last month. Here they are:

1. target on more "less competitive" key phases, trying to reach top 50 in some search engine
2. use of sitemap to accknowledge google of my page update. Before I use sitemap, google kept my cache copy which is 2 weeks ago. Now it is about 2 days ago. It was a great improvement.
3. added link page for link exchange for better link popularity. In my experience, link market is the best free link exchange service site.
   
4. added more useful links on related topics

On the coming month, Im trying to do:

1. find ways for more web traffic (search engine & affilate programs)
2. redesign the web layout
3. divide articles into categories, and add a clear list of SEO tips as the blog grows

Thanks everyone!!
