....and.... remember
SEO - even in your blog posts:
1. Use <h1> tags for blog titles, and <h2>, <h3> tags as well - all tags can be styled using CSS to reduce size, but still be seen by search engines.
2. Use keywords of the blog post in <alt> tags if you use an image in the blog post.
3. Try to use a related link to another well-known/read website/blog inside each blog entry. Always use the correct website name in the
anchor text of the website link.
4. Read your stats. What are the most popular search terms that people are using to find you blog? Is this worthy of more blogs on the same subject, or maybe even a separate webpage expanding on that subject?
5. Don't try too much at once. Experiment. Analse the results. Try something else.
It's fun & games really :)
