Google Analytics is a free service from google that lets you see where your website traffic is coming from. This is great way to track what is working and what is not with your advertising. If you want to get a little bit more in-depth, you can track what are called conversions.

These are specific actions that a user does that quantifys a favorable response I.E. filling out an application, or submitting a question. With this you can track not only where your traffic is coming from, but what advertising source is generating the most business. If you don't have google analytics you can contact your website provider they can install it for you. If you need help with seting up conversions and analyzing the data you can call us!
