In my last blog posting I commented on many marketers’ skeptical response to the vastly superior performance of loyalty members versus non-members. While few would argue that a gap in frequency and order value between members and non-members should exist, the doubters contend that the performance is merely a manifestation of inherently better customers opting-in to a program that rewards their existing loyalty.
My response: Of course we expect to see a higher proportion of best customers enrolling and participating. But, a deeper dive routinely shows that responsiveness, frequency and order value improve even within this self-selecting segment.
So, how can we measure the impact?
The single key is the ability to isolate similar groups of customers for comparison in order to remove the “bias.” For companies that already have strong customer capture (e.g. on-line/catalog companies and other retailers/travel/hospitality companies that have strong customer identification), pull a relevant subset of non-members that exhibit nearly the same pre-enrollment behavior of the loyalty member group. For instance, if the average frequency of the new member group prior to enrollment was 1.7 purchases and $125 average spend annually, select a group of non-members with the same metrics. With this rigor, comparison of behavior post enrollment (or alternatively non-enrollment) will clearly illustrate the lift most-directly correlated with this single change in customer relationship.
For businesses where the vast majority of customers shop anonymously, we recommend holding out a market for comparison – essentially piloting the program in order to see the overall impact on purchase metrics. In the online world, a number of platforms allow the ability to serve loyalty membership information to selected members only – in effect creating a virtual pilot group.
A final note on new customers. New customers by their nature do not have prior purchase history from which to compare. Again, we’d expect customers who are more likely to be best customers to enroll upon their first purchase. Rather than discount this as self-selection, be sure to use this insight as a means of reaching out to this group with a great new member/customer marketing program. Clearly this is the group who will be most receptive and will yield the highest return on your marketing investment.
