As the Director of Client Services for ATG’s automated recommendations service (an increasingly hot technology in the industry), I am bumping into some unexpected questions from retailers about how the tool actually goes about making recommendations to consumers. They’re seeing that some of the recommendations it generates don’t seem to make sense at first glance. As I think about it, the questions are very understandable and probably more common than I had realized.
Predictive Recommendations– A quick primer
First, here’s just a little background if you’re not familiar with what an automated recommendations service does. It’s basically a predictive merchandising solution. This tool, which operates as an on demand service running on top of an existing commerce site, recommends products for individual consumers, based on each person’s specific shopping behavior. Sometimes called “predictive merchandising tools,” these kinds of services are helping merchants generate higher average order value and increase conversion rates.
But don’t let this simplistic explanation mislead you into thinking this is simplistic technology. There is a great deal of extremely sophisticated science that goes into creating the algorithms that drive the service. Behind the scenes of a shopper’s online experience, the services is observing behavior and employing very complex predictive models to collect all sorts of behavorial and demographic data points, and then recommends products to those shoppers based on the collected behavior of their shopping session and shopping sessions of other similar consumers.
These tools actually “learn” shopping behavior and grow smarter with every session they observe. As a result, the tools know when I am interested in purchasing a new pair of jeans vs. when I’m looking for some really high-end perfume.
What does a duffle bag have to do with a black blazer?
But back to that question I referred to earlier. One major clothing retailer recently asked me, “If this tool is so great about recommending the right product, why doesn’t it always recommend the matching pants with the jacket of a clearly identify pant/jacket set?” That is a great question! It turns out that while retailers market pants and jackets as sets, many women actually buy clothing as separate pieces – either the jacket or the pants, but not both together. In addition, the automated recommendations tool has learned over time that the shopper is far more likely to buy the black blazer in the same shopping cart as a duffle bag. No human being would ever have predicted that combination, but the recommendation service has observed the correlation over time. So why not serve the shopper product ideas which include both the merchant-defined clothing sets and the products discovered by the automated tool? By the way, yes, the tool can be tuned to display catalog style sets (but wouldn’t that spoil the fun?).
Best practice: Have predictive technology coexist with merchant-defined rules
Back to that retailer. As he and I continued talking, it became clear that the best practice is to combine manual and predictive merchandising techniques as a comprehensive strategy. The retailer will continue to market products in sets, as doing so helps create a fashion look and suggests buying options. But they will also use a predictive recommendations engine to get inside the mind of the shopper and suggest products which meet the shopper’s immediate desires.
Data from the automated recommendations sessions will suggest new trends and will help the retailer lead the fashion scene. So this retailer will have the best of both worlds – an ability to promote a certain look every season, and to lead the fashion industry in trend identification.
