How I Used Association Rule Mining to Cross-sell At Scale – Mathias Schrøder

I have been wanting to start cross-selling at my family's webshop Seniorshoppen.dk for a while. The problem is that we sell 500 different products, so I have been pushing it off as it would take a lot of time to manually select possible cross-sells for each product we sell. Therefore, I have been thinking a lot about how to automate this best using machine learning or other techniques, I just haven't got around to doing it. For Black Friday we decided to require our customers to buy a minimum of two products to get a 25% discount. So, it was a natural time to actually execute on this to "help" our customers choose a second product for their Black Friday shopping spree. This is how I did it.
