How do I set up goals and funnels?

In order for Google Analytics to calculate goal conversion metrics, you must create one or more goals. Before setting up a goal, please make sure you have the following requirements.

Requirements

* The name of the goal: Specify a name that you will recognize when viewing the goals within each set of your reports. Examples of names you might use include "email sign-up"or "article ABC download."
* The defined funnel: You may specify up to ten pages in a defined funnel. Although funnels are optional, defining one can help you map where visitors drop off during the path to completing a goal.
* The value of the goal: Google Analytics uses an assigned goal value to calculate ROI, Average Score, and other metrics. A good way to value a goal is to evaluate how often the visitors who reach the goal become customers. If, for example, your sales team can close 10% of people who request to be contacted, and your average transaction is $500, you might assign $50 (i.e. 10% of $500) to your "Contact Me" goal. In contrast, if only 1% of mailing list signups result in a sale, you might only assign $5 to your "email sign-up" goal.
