What are explicit and implicit feedback?
Explicit feedback is collected as users interact with the recommendations. Implicit feedback infers user preferences by analysing actions like purchase history, navigation history and time spent on web pages.
Are there recommendation engines for mobile environments?
Yes. Automated mobile recommendations offer personalised, context-sensitive recommendations, which can be based on location, season, daypart and more.
How do you measure a recommendation engine’s performance?
A/B testing can reveal a system’s performance. Marketers use several metrics, including customer lifetime value, click-through rate, conversion rate and ROI to measure results.
