“[C]ustomers in the experiment group were more likely to click on the games shown in the recommendations section, at a rate almost 15% higher than the control group,” they said. “The increased personalization means there is an even greater variety of games being shown in this section, and customer impressions are more evenly distributed among them.
“To get a feel for the breadth of titles that were being visited, we measured how many games members of the experiment group visited via the ‘Recommended For You’ section compared to a sample of customers who were not in the experiment for a few days. The results were very promising: we saw a 75% increase in the number of unique games visited, and a 48% increase in the average visits per game.”
