• Use an interesting title for your blog and each of your blog posts. 
• Limit each of your posts to one topic, keeping your pages focused.
• Keep your posts not too short, and not too long.  This keeps your readers interested and returning.
• Provide a list of your top 10 blog posts on your site.
• Make sure your tags, categories, labels, etc. also make good keywords.
• Use your keywords as often as possible, but only in a natural context.
• Use a blog service like WordPress, Blogger, etc.  These sites already have high content churn, and attract frequent indexing.
