SEO - why so late?

This week's reading I focused on "What is search engine optimization (SEO)?" and "Anatomy of a Blog Post Well Received". I felt like these articles and videos were very helpful. The articles gave a lot of tips and ideas of how to promote your blog ,as well as, how to generate traffic to your blog. And most of all, how to analyze the traffic your blog is attracting. However, I felt that if they were introduced earlier in the semester, they would have been even more helpful. What do you guys think ?
