Internet marketing can be very intangible. Although Google Adwords and MSN AdCenter gives you valuable data, it doesn’t show you the complete success of your PPC campaign. It’s hard to see the results, when nearly every part of the sales process is done online.
Your sponsored ads might drive 80% of the traffic to your e-commerce page, and you might not even have a clue that your PPC campaign is working well. It can be very difficult to understand how much money you are making (if any) from your PPC campaign if you do not take the right steps to learn its profitability.
