What does assigning a value to a Google Analytics Goal enable?

Goals measure how well your site or app fulfills your target objectives. Defining goals is a fundamental component of any digital analytics measurement plan. Having properly configured goals allows Analytics to provide you with critical information, such as the number of conversions and the conversion rate for your site or app. When you set up a goal, you have the option of assigning a monetary amount to the conversion. Each time the goal is completed by a user, this amount is recorded and then added together and seen in your reports as the Goal Value. Tip: You can change the currency unit for the goal Value in your view settings.
