Since most web sites set cookies, you can look at this data yourself by inspecting the cookies via your browser's menu. For example, if you are using Firefox on a Apple computer select FIREFOX > PREFERENCES. Select PRIVACY in the tab bar and click on the SHOW COOKIES button to see a list of all cookies set on your browser - by domain or I.P. address. Once you select a domain or I.P. address from the list, click on the cookie name to see its settings. You can choose to remove the selected cookie(s) if you wish.

When a cookie expires, it is no longer present on the web browser and therefore not sent to the server. As you can see from the cookie table listed above, the Google Analytics cookies have a variety of expiration dates, all of which serve different purposes.
Google Analytics sets an expiration date of 2 years for unique visitor tracking. However, if you delete these cookies and revisit this website site Google Analytics will set new cookies (including new unique visitor cookies) for each visitor.
