When doing any marketing or advertising for your business, it is important to track all the information that comes from these activities.

But how do you know what information is the best to collect?

The most important statistics are how much money and how many customers.

The easiest way to do this is to record every sale transaction and add a reference of what advertising that customer came from.

Then you will be able to calculate the total of how many customers and how many sales came from each campaign, and record these on a daily basis.

When you do this over a week or a month, the data can then be averaged or totaled, and will give you lots of detail for the return on investment.
