In the previous articles in this series I discussed the importance of baseline data and what you should be measuring. I’m now about to dive into the most important metric that you can ever use to evaluate the success of a traffic test, the normalised revenue per thousand visitors.
I want to apologize to all those readers where mathematics isn’t your strength….that’s OK. I will try and make this article as simple as possible so that it gets across the point.
Many domain owners have learned to pay attention to the revenue per thousand visitors (RPM) that is produced by the various parking companies. The reason for this is that it takes into consideration the variation in the traffic levels for each domain. So really what is RPM? The formula for RPM is the following:
Revenue / visitors x 1000
This makes sense until you get under the both revenue and visitors. For a start, visitors is actually filtered traffic and since each parking company filters traffic differently than this number changes for each company. Another way of viewing visitors is:
Raw Traffic x Parking Company Filter
Then there is the Revenue number. What revenue number should you be using? The estimated numbers, the number confirmed 2 days later, the number less clawbacks, the number less account adjustments etc. There are about 7 different revenue numbers that need to be examined for each domain!
For example, over the years we found that some monetisation companies would say that they will pay more for domain traffic during the month and then do an account adjustment at the end of the month. This meant that they were effectively bribing the traffic routing algorithms to during the month and then taking all the money back at the end. To understand who the winner is you need to take this type of behaviour into account.
So let’s look at our formula for RPM now:
(7 Different Revenue Numbers) / (Raw Traffic x Parking Company Filter) x 1000
Because we don’t know what the parking companies use to filter their traffic let’s imagine that we can actually count the Raw Unfiltered Traffic that we send each company for each domain. Let’s also imagine that we are able to sort out the revenue and with a bit of magic work out the actual revenue number for each domain each day. The formula then simplifies and looks like the following:
(Adjusted Revenue) / (Raw Traffic) x 1000
This is the normalised RPM (nlRPM) and it allows you to directly compare any monetisation company against another. What we do is count each bit of traffic that we send each company each day and then measure the adjusted revenue that the traffic generated. When you do this for all companies you get a number for each company so that you can then know which one is actually paying the most.
Let me say from the outset that this starts to get REALLY complicated! This is also what you need to consider if you want to know who is actually winning your traffic at any point in time.
Thankfully, at my company, ParkLogic, have servers and algorithms that all the automatic mass calculation of all of these numbers. We then use these numbers to route the traffic to the winning company. Each day, we have servers that all they do is process data for about 15 hours to get to the nlRPM.
So let’s imagine that we have a domain that has a huge nlRPM and it’s smashing the baseline data out of the ballpark. Do we claim victory? Heck no! Even when you have the normalised data you need to understand WHY the domain is winning.
For example, let’s imagine that you have an education related domain and you are comparing the baseline data in July versus September. I can almost guarantee that the nlRPM will be higher in September as school’s back and this will attract the educational advertisers!
To put everything into context, the nlRPM is like the science of domaining….you have to have this number really know how you are doing. Understanding why the nlRPM is changing is the art….this is where experience comes into play.
I think that the gold rush provides a really good analogy for traffic monetisation. In the past, there used to be gold lying on the ground everywhere and you didn’t have to do anything to pick it up. Today you have to drive a shaft 3 miles deep and run side passages that follow the seam of gold. This is what I’m talking about with the nlRPM. The gold is still in the mine but you just need to dig it out and this is what I do day in day out.
