Don’t you think it is correct, that one can’t manage or improve something what has never been measured? If you are marketing online and wish to earn money, there is simply nothing that is more important than measuring what does work, and what doesn’t. How to measure the progress best without being stuck in the paralysis of over- analysis?  This is a skill you need to know, and here you have three different ways of how to do it.
The fist one is to find out how much is your average customer worth. This is done simply adding up how much did the customer cost you, and subtracting it from your initial revenue from a customer. For example, if you need to pay 100 hits at .24 cents each in order to generate two sales at 47 dollars each, then each of those customers costs about 12 dollars to generate. Every customer is 35 dollars worth.
Then you have to take into consideration the cost of processing the payment and other kinds of overhead. Once you are through with this process, you have a true idea of how much you are making from each customer. Then you you should pass over to the next principle, which is measuring the lifetime value of each customer.
This will take a bit longer to do, but you will be rewarded, because you will be able to decide whether you need to pay to get more customers or possibly increase each one’s lifetime value. If you have several proposals clients can benefit from, you factor the profit of those products back into the equation.  For example, imagine that you have a data base of 5000 people and 500 of them buy your service at $100. This adds another ten dollars to the value of those customers, which increases your value to 45 dollars.
Going through the process, you will see that there are other variables involved, but this should give you an overview. When you will find out how much a customer is worth, you can put together a plan for using the third measurement key. The third key is measuring measuring the motivation for a purchase of your clients, which is done by asking them questions conducting surveys. This is the most important way to measure your marketing process, because it will it will show you how to move forward.
When it comes to marketing you can come up with all of the great ideas that you want, but in the end the customers are going to be the ones who decide what really works. So it is much more wise to find out from them first, and then create your product or service? Once you understand the worth of gaining a new customer and what their lifetime worth to you is, as well as understanding what will motivate a person to make a purchase, you can save a ton of money on marketing and really rake in the profits.
