What are cookies?
A cookie (web cookie, or browser cookie) is a small file which is stored on your computer when you visit a website. These files are used by the website for a number of things but mainly to anonymously track or trace where you have been on the website and what you are searching for. Cookies do not contain any information that personally identifies you.
Cookies may be either “persistent” cookies or “session” cookies. A persistent cookie will be stored by the browser and will remain valid until its set expiry date (unless deleted by the user before the expiry date). A session cookie will expire at the end of the user session, when the web browser is closed.
For a more details read more about cookies on Wikipedia.
In order to achieve this we use the popular Google Analytics system which shows us what our most popular sections are, what our users type into Google in order to find us and how often visitors view our site.

Obviously, doing this may have a negative impact on the usability of many websites.
