What it is

A recommendation engine combining collaborative filtering, content-based filtering, and deep learning surfaces the right products to each shopper at the right moment. Retailers typically see a 15–30% lift in conversion rate and a 10–20% increase in average order value within 3–6 months of deployment. The system continuously learns from browse, purchase, and session data to improve relevance over time. It can power homepage widgets, product detail pages, cart upsells, and email retargeting.

Data you need

Historical purchase transactions, product catalog attributes, and user browsing/clickstream event data covering at least 6–12 months.

Required systems

  • ecommerce platform
  • data warehouse
  • marketing automation

Why it works

  • Maintain a clean, well-attributed product catalog with rich metadata to power content-based fallback recommendations.
  • Instrument all key user interactions (views, clicks, add-to-cart, purchases) with a reliable event tracking pipeline before model training.
  • Run continuous A/B or multi-armed bandit experiments to validate each recommendation placement and iterate quickly.
  • Establish a retraining schedule (weekly or triggered by performance thresholds) to keep models fresh.

How this goes wrong

  • Cold-start problem: new users or products receive irrelevant recommendations due to insufficient interaction history.
  • Data sparsity: low transaction volumes make collaborative filtering ineffective, producing generic or repetitive suggestions.
  • Model drift: seasonal shifts in demand or catalog changes degrade recommendation quality if the model is not retrained regularly.
  • Lack of A/B testing discipline leads to inability to measure true incremental impact versus baseline.

When NOT to do this

Do not build a custom deep-learning recommendation system if your catalogue has fewer than 10,000 SKUs or your monthly active users number in the hundreds — off-the-shelf tools will outperform a bespoke model with far less investment.
