Most people are very familiar with the Adwords Call Tracking with a forwarding number that is part of the call extension process. Others are surprised to know that you can also track the phone calls once the user hits your site. With a small piece of code, you can have Google dynamically swap one main phone number on your site with a tracking number. This is a great way to keep gauging the effectiveness of your PPC campaigns!
