TIP
How can a website track me online?
The most common method is by using a
cookie
, a small text file that it stores on your Mac
Pro. Cookies are used routinely by any website that needs to “remember” information
about your session at that site: shopping cart data, page customizations, usernames, and
so on.
A
third-party cookie
is a cookie set by a site other than the one you are viewing. An advert-
ising site might store information about you in a third-party cookie and then use that cookie
to track your online movements and activities. The advertiser can do this because it might
have an ad on dozens or hundreds of websites, and that ad is the mechanism that enables
the site to set and read its cookies.
