Good reading article. I have learned a lot.

We’re having a discussion over at another dev forum about which is better SEO tactics, specifically regarding the title structure. The question is which of the following is better, from an SEO as well as an accessibility point of view (if there is any actual difference)?

1) (title)Article name / Category name / Domain name(/title)
ex: (title)Intelligent site structure for better SEO! - Articles - Opera Developer Community(/title)

or 2) (title)Domain name / Category name / Article name(/title)
ex: (title)Opera Developer Community - Articles - Intelligent site structure for better SEO!(/title)

Just curious...
