Key Performance Indicators (KPI’s) for eCommerce

11/06/2018
  • We are going to tell you which are the Key Performance Indicators or KPI's for eCommerce. Learn about what you should measure to win

  • We are going to quantify our business success. In this post, we present a list of Key Performance Indicators(KPI's) for eCommerce that will help measure how well you are doing things and what needs to be improved. 

  • Brief definition of KPI's

  • Let´s remember that a KPI or key indicator of your online store´s performance is a numeric value that we set ourselves as objective of improvement in the performance of our eCommerce

    It is important to differentiate between metrics and KPI's because, while the metrics are data that we get from the analytical tools, KPI´s are those same metrics but with a strategic component. In other words, all are metric, but not everything is used as a reference. We explained that in detail in this post called web analytics tips for entrepreneurs: metrics, KPIs and 4 best tools to analyze the results of your strategy. 

    Finally, before we get down to business, we should say that there is an important nuance: Key Performance Indicators always have to start from a measurable and quantifiable goal with accurate figures. Selling more is not a KPI. However, increasing the average ticket 15% on PPC campaigns would be so. 

  • List of basic KPI’s for eCommerce

  • We are talking about strategy and this is something that does not accept a single recommendation. Every business is different and has its own needs goals even though it is part of the same area and has a segmentation similar to other competitors. Also, businesses are alive, so they change throughout their lives (and their Key Performance Indicators with them) 

    However, there are a series of basic KPIs which can be of help to start to measure. From now on, you can increase this list with those you consider appropriate

  • #1 – Conversion rate

  • This KPI is the most important of all. It is about knowing the number of visits that you needed to get a sale. This is expressed as a percentage. It is really simple to calculate, just apply an easy formula: 

  • Conversion rate = (Number of sales / Number of visits) x 100

  • In this way we will have clear that if we want to increase sales at a certain percentage, either we increase visits or optimize those we already have by using CRO techniques. That is why it is basic to measure and know our conversion rate. 

  • #2 – Gross margin

  • You can find it in much documentation about eCommerce. It is called Gross Margin (whether we like it or not Marketing receives many anglicisms and acronyms from English terms). 

    In this case, we are referring to margins, not to the number of sales. The noticeable difference is that we are talking about finding the benefit that they provide (Of course: taxes excluded). It is calculated as follows: 

  • Gross margin = (Sales – Cost of sales) / Sales

  • #3 – Average ticket

  • This is one of the critical KPI because it allows us to play much strategically. It refers to the amount that the average user spends on our eCommerce per order. If we manage to increase it, with the same investment in acquisition, we have a higher benefit. To calculate it, you have to: 

  • Average ticket = Total amount sold / Number of orders

  • #4 – Loyalty KPIs: rate of recurrence and CLV

  • It is much harder (and expensive) to make a new client that to sell again to a loyal one. Therefore, we must be clear at all times how many of our buyers return to place orders in our store and how often. Here we can talk about various KPI's in reality. 

    On the one hand, we have the recurrence rate, which is basically the amount of customers who buy more than once in your eCommerce. The calculation is as easy as all we have seen so far: 

  • Recurrence rate = (Total number of orders / Number of customers)

  • We would also highlight the so called CLV (Customer LifetimeValue) It consists of knowing how much we obtain from each client during his life as such. I mean: 

  • CLV = Average ticket x Number of recurrent sales  x Customer´s lifetime

  • #5 – Cost of acquisition

  • It is also of enormous importance being aware of how much we are investing in acquisition, how much cost us sell. In fact, one of the strongest points of online strategy, is that we can assess the performance of each investment very accurately. 

    To calculate the CPA we need just an operation as simple as that we have seen so far: 

  • Cost per acquisition = Costs generated by sale / Number of sales

  • The more exhaustive we are in the allocation of the cost, the better accuracy this KPI will have. In other words, to be able to add all the costs involved (SEO, SEM, human resources…)

  • #6 – Cancellation rate

  • The so-called churn rate is a key indicator that should be kept as low as possible. It is the rate of users who unsubscribe from a service. If your eCommerce sells products also will also affect it. 

    The most obvious example is the users who unsubscribe from our newsletter and our database. Also, it would also affect business as subscription boxes or any additional services such as insurance or Premium programs. 

  • To calculate the cancellation rate we will divide again, always keeping in mind that this rate is calculated within a specific period: 

  • Churn rate = Lost suscribers / Suscribers we initially had

  • The truth is that we could continue talking because there are many interesting KPI's, but the important thing is that you analyze your business before starting with the strategy

  • What do you think you should measure? Which are t he Key Performance Indicators that most affect you?
