The way the Google in itself make it go differ from all other search engines..They had got amazing crwals and spiders that work continuously to deliver best results.
Simply, they have more money then the other search providers. They are indexing the new sites a lot faster than Bing for example, and this requires lots of resources. Something that google can afford.
Simply the one and only legend in this market...How every it try change it self to be best experiencew for user..
May be Google's stock price is higher than others it has all the resources and potentials to be on top of all
