Cache |

Click-through |
This
refers to the action of actually clicking on an ad. Advertisers assume

points to.
|
Click-through

Connection
Speed |
The
speed of the connection (the bps -- bits per second) that determines
the rate information can be transferred from the Internet to a particular
computer. This depends on the type of connection, i.e. modem, cable,
DSL, etc.
|
Conversion |
Measures
the rate of goal achievement. It could be used to mean the number
of orders or leads that are generated from an ad.
|
Cookie |
A
cookie is a small text string that is placed on a computer. When an
Internet browser fills out information in a form, when the browser
returns to the site, an application checks for the existence of a
cookie. If one is found, the information that the user submitted on
the form can be retrieved from the database. If a user submits information,
this allows their subsequent visits to the same area to be tracked.
Although several Internet applications are dependent on cookies, their
use can be disabled in the browser application. For more information
check CookieCentral.com.
