We like to provide all of our clients and prospects with accurate, fresh data when it comes to what search engines like . I often find myself referring to Google for search engines like I might refer to Kleenex for a facial tissue.  Clients will often ask if we are just focused on Google.  The answer is "not really".  The algorithm is basically the same for all of the big players:  Google, Yahoo, and MSN.  However the market share is truly held by our "do no evil" friends at Google. 

The latest data from www.searchenginewatch.com:  "Google is pulling in 62% of the online searches, with Yahoo at a distant second with 20%".  When it comes to blogging best practices when focusing on SEO, you truly have to consider where the majority of your organic results will lie.  Good luck and keep blogging!
