Hi.....optimization is same for all search engines whether you do it for Google, Yahoo or Bing.....ofcourse the search engine ranking factors of all search engines defer as all have their own different ranking algorithms.....optimization remains the same only the ranking factors of search engines defer......
Their is no much difference, i think. Almost all the basic things are same to follow like URL, Meta Tags, Internal linking.
