WHAT ARE COOKIES ?
Cookies are small bits of text that are downloaded to your browser as
you surf the web. Their purpose is to carry bits of useful information
about your interaction with the website that sets them.
Contrary to a common
belief, cookies do not contain software programs, so cannot install
anything on a computer. Cookies generally do not
contain any information that would identify a person. Usually they
contain a string of text or "unique identifier". This acts like a label.
When a website sees the string of text it set in a cookie, it knows the
browser is one it has seen before.
If you use a different
computer, open a new web browser or delete your cookies, the website
will treat you as if you have arrived for the first time (and a new
cookie will be set).
What are cookies used
Cookies can be used for a
variety of reasons:
- to help remember your preferences on a site
(whether you read the oldest or newest
comments first; the volume on the video player)
- to understand how you and other users are using the site
(to tell what the most popular news story
of the day is; to record how you responded to a new design
or version of the site)
- for logging in to a service or to make sure you're logged in securely
(these cookies may contain
information such as your email address and your name – the information
you gave when you signed up. The
website you signed up to is the only site that can access
The cookies that appear
to cause the most controversy, however, are for managing the advertising
you see on a website.
This is particularly the
case when websites set a cookie from a separate advertising delivery
company. This cookie can record when and where you saw an advert, where
in the world you might have been when it happened and whether you
clicked on it.
The cookie will send this
information to the cookie owner, who records this data and uses it to
make sure you don't see the same advert too many times.
If websites choose to
pool some of the information this type of cookie collects as part of an
ad network, the systems used by advertising delivery companies can
create "segments" of browsers that display similar behaviours.
They will use this to try
to draw conclusions about what the people behind the browsers might be
interested in: "basketball lovers" or "hair product enthusiasts" or
"adventure holiday takers", for example. Cookies that do this are known
as third-party advertising cookies.
Over time they learn
which types of adverts are most effective to these groups and can sell
this service to advertisers.
