Google has been estimated to run over one million servers in data centers around the world, and process over one billion search requests and about twenty-four petabytesof user-generated data every day.
As of December 2012, listed the main U.S.-focused google.com site as the Internet's first most visited website and numerous international Google sites as being in the top hundred, as well as several other Google-owned sites such as YouTube and Blogger. Google also ranks number two in the BrandZ brand equity database. The dominant market position of Google's services has led to criticism of the company over issues including privacy, copyright, and censorship.
