Tracking -The final component

Tracking how an individual ad doing is the single most important part of succeeding with your online advertising. Without effective tracking your success will be anectodal, and hard to judge. So each individual ad should have a seperate tracking code, in order to track each change you make. While this might be time consuming, measuring the effectiveness of each individual ad will pay off over time. I would suggest one of the tools such as GoToast to automate tracking.
