Conversion tracking
From Adylitica
Conversion tracking is a feature in the AdWords management campaign interface that allows for the measurement of conversions integrated with the advertisement that led to the conversion.
Google lets you set a dollar amount for conversions, which can tell you how justified your CPCs are. This is important in trial and error testing, however all conversion information will not be used by Google outside of the management interface, it is purely for your information.
Conversion tracking is highly recommended and is one of the pillars of intelligent adwords optimization, as it allows you to intelligently decide budget placement and settings.
