The number of search engines on the Internet are so numerous, thousands or perhaps tens of thousands. Do we have to do a blog optimization for all search engines? My own focus on only one course that is the biggest search engine Google.
Why should the focus to one, not for all the search engines? because algaritma search engines are different from each other, to understand the character of each search engine needs a long time and it's just a waste of time.
Why should the focus to google not to another, such as Yahoo or Bing? This is only an option, if you want to focus on the optimization Yahoo monggo yes, or if you want the focus to bing ya go ahead
