I am using Google, since I am using internet because I learnt internet only through Google. And I am working as Lead Researcher, we cannot imagine our profession without Google.
Trust me most of companies and workers depend upon Google.Compare with others search engine its very fast and accurate in their results. I compared Google with yahoo bing, MSN Search, Aol search but none of them are equal with it. In the case of SEO it is very much useful trust-able one.
Most of the companies depend upon Google rankings for their on-line sales. So most of companies sales revenue will decide by Google ranking itself.
When I open the internet I will reach my target site with the help of Google. Not only me most of internet users will do this as procedure.
Finally, I would to say many to Google which make our internet process as easiest one.
