Why only Google for SEO?
 

Many search engines are available in on the web but most of the webmasters are using Google. I want to know that why webmasters are emphasizing on Google for doing SEO and why not other search engines? And, how they do SEO effectively only in Google and get the result?

Google is the king of all the Search Engines..People search every information in Google, that's why many are doing SEO only for Google..Following all the techniques in Google Web Master Guidelines, websites are effectively doing SEO only for Google....
