Not long ago, the main source of Web traffic data was clickstream (the recorded paths that visitors take through a Web site). Even now, many people feel that Web analytics = clickstream. However, clickstream is just a small piece of a much larger Web intelligence picture. Unfortunately, clickstream is still the major source of data used for Web decision-making by a significant number of professionals. Therefore, many companies are confounded by the lack of real, actionable insights that clickstream offers.
Modern practitioners have adopted the concept of Key Performance Indicators (KPI’s). These enable professionals to look beyond the raw clickstream data, and illustrate how well a site is performing against the real-world business goals that have been set. Each company has different business models, and different companies will likely have a unique mix of KPI’s. Below are some common KPI’s that a typical e-commerce Web site might be most concerned about, and their definitions in terms of an e-commerce operation:
Conversion Rate
Conversion Rate is the percentage of visitors who complete a transaction, based on the marketer’s intended action and is calculated as:
(Number of Sales / Number of Visitors) X 100 = Conversion Rate
Conversion Rate is an important KPI in that it enables the enterprise to keep a pulse on the Web site’s overall ability to turn visitors into paying customers. A rising Conversion Rate demonstrates that sales efforts are improving overall, although this KPI cannot indicate what specific strategies have worked. If this KPI value is falling, it signals that action is needed, although it cannot diagnose what the specific problem might be.
Conversion Rate for a Specific Campaign
Similar to “Conversion Rate”, this is the percentage of visitors who complete a transaction for a specific marketing campaign. Conversion rates should not only be monitored against benchmarks monthly, but also before, during, and after campaigns, special seasons, etc. Landing pages are often used to make it easier to measure the response to a specific campaign.
Average Cost Per Conversion
The Average Cost Per Conversion describes the cost of acquiring a customer. In terms of e-commerce, the “conversion” refers to an actual sale. Here is the formula:
Sum of Acquisition Marketing Costs / Conversions = Average Cost per Conversion
Should a campaign’s Average Cost per Conversion rise markedly, it likely indicates that a costly program has been launched, and that it is failing to drive an appropriate number of conversion outcomes. Such a program should be monitored closely, and well thought out measures should be undertaken to remedy the problem if no improvement is seen.
Average Order Value
The Average Order Value or AOV is the average amount spent for a single checkout purchase on a retail site for a particular customer segment or group. It is calculated as follows:
Sum of Revenue Generated / Number of Orders Taken = Average Order Value
Working to increase the Average Order Value is an effective means of increasing revenues. However, it’s crucial to monitor this particular KPI in conjunction with the Conversion Rate. For example, consider a situation wherein most customers buy high-ticket items in small numbers. The AOV will be high, as most orders will be of a large monetary value. Outside of the context of Conversion Rate, these would appear to be good numbers, however the overall revenue may actually be down. This can happen when each customer has spent a lot of money, but there are not many actual customers. Also note that when the AOV falls, but the Order Conversion Rate rises, the revenue per visitor should stay roughly the same. However, when both AOV and Conversion Rate shrink, revenue per visitor will likely be strongly impacted in a negative fashion.
Wish lists and recently viewed product lists that are saved across visits (even for unregistered customers) should be employed to remind shoppers about items of interest, and make it easy to buy when they are ready. Enticing every customer to spend more with every purchase is an essential part of maximizing revenue.
Average Items Per Cart Completed
This is the measurement of the number of units or items in each successfully completed cart. Calculated as:
Sum of Products Purchased / Number of Completed Shopping Carts = Average Items per Cart
This KPI is a good indicator of the success of up-sell and cross-selling efforts. However, this metric may decrease upon the implementation of a successful promotion of a single item, thereby increasing the number of single-item orders. If no recent efforts have been made to improve up-sell and cross-selling opportunities, an increase in this KPI might show that better-qualified traffic has been attracted to the site, or that a very successful campaign has been established.
Shopping Cart Abandonment Rate
This is the percentage of visitors that start an order by initiating the check-out process, but depart before the purchase is completed. This KPI is calculated as:
(Number of transactions completed / Number of transactions started) X 100
Regardless of industry, e-commerce Web sites experience some rate of shopping cart abandonment. If this KPI begins to rise, it is time to ensure that the checkout process is as streamlined as possible. For example, it has been shown that streamlining the checkout process by removing even one Web page from the purchase routine lowers the abandonment rate by a significant margin. Another common problem is that some retailers do not disclose all additional shipping rates or handling fees on their products up front, only to disclose them later during the checkout. Additionally, it is best to offer as many payment options as possible. Enterprises should avoid placing any extra marketing content in the shopping cart area that might distract purchasers. Anything that retailers can do to make it quicker and easier for customers to make an informed decision to buy and check out quickly will lower their Shopping Cart Abandonment Rate KPI.
