strategy? Google collects information such as what language visitors use, to what advertisement’s may be useful to users based on the terms they have searched, this information is collected in two ways: information given to Google, so if for example users sign up for a Gmail or a Google + account they will give details such as name, address, contact details. Information is also gathered through how users utilise their services; what they search and location. The aim of collecting such information is to tailor search results to fit the individual, this has some advantages as well as disadvantages.
Privacy problems are particularly pertinent to those who share a Google account with other members of their family, so maybe you want to surprise your mum for example with some concert tickets for her birthday, if you both use the same computer Google may come up with ads for the concert tickets, the next time your mum is on the computer giving your surprise away. This could also apply to searches relating to sensitive topics such as meetings in your calendar.
