Yahoo details
 

I am aware about Google�s popularity. I also know it is very important to get optimized on Google. Rankings on this search engine. However, I would like to broaden my knowledge about the other search engine, i.e., Yahoo. Though Google is popular, we can�t neglect the 2nd highest search engine. There are many people who are also equally using Yahoo for the search purposes. What is purpose of getting optimized on Yahoo? Are there any major criteria? Can you please help me with the appropriate reply?
