Why do you need to keep an eye on the sales data in your business?It happens to the best of us. You put out a product, and it's not just selling as much as you feel it should. Or maybe it did sell for a while, but now... not so much. So what do you do? The first thing to do is to check the data and see what it's telling you. Is there actually a problem? You might find that yes, things are a bit quiet. But maybe you know that's because you have a very seasonal business and things are always a little quiet for you at this time of year - it's a known trend in your business. And if you find that you're making more money this month than you were last month or the one before, then great. You're winning! And definitely doing something right, so now it's a matter of working out what that is so you can make more of it. But what exactly are the metrics you should keep an eye on? What's your EPSPM and why does it matter?We go on and on about this one. But it's important. Your EPSPM (bit of a mouthful, yes) is your Earnings Per Subscriber Per Month. And it's quite self-explanatory, really. It tells you how much money you're currently making for each of the subscribers on your list.How to work it out? Look at how much you made in the last month, for example, and divide your sales by the number of subscribers you had on your list. If you made $1,000 and you have 1,000 subscribers on your list, each subscriber is earning you $1. That's the figure you want to look at - once you know that, you can easily see whether that goes up or down month on month. And you know why this is a fundamental metric in your business? Because while a lot of people are focused on growing their list, if you double your list but your EPSPM doesn't go up or, worse, goes down, then having more people on your list isn't a good thing! Because you're earning less, not more.So if this month you're making $1 per subscriber and next month you double your list from 1,000 to 2,000 people, but you're still making $1,000, you've reduced the effectiveness of your email marketing because your EPSPM is now $0.50 and not $1.Focus on making more money from your listSo here's a quick tip. Focus on making more money from the list you have rather than growing your list further. As we've said many times before, this is the exact reason why we got good at email marketing. Because we couldn't afford to build our email list by investing in ads. And we couldn't afford to upset people to the point they'd unsubscribe from our list either! So we had to really focus on how to earn more for each subscriber.So our tip to you is to track this...
