It is virtually impossible not to provide information about yourself when you are on the internet. Some of this information is suitable for targeting individuals with advertising. Google in particular gains a great deal of useful information about its users whenever they visit its various websites. Through its search engine, Google has accesses to all the things a particular person searches for as well as when they searched for it. Many people have a Google account, from which Google gains demographic information such as their sex, age and location. Google also has access to information about people from their Gmail messages and from the videos they watch and the comments they leave on YouTube.
