Netflix is known for recommendations, but the deeper lesson is interface personalization: which titles you see first, which artwork you see for the same show, and how rows are ordered—all tuned to increase the odds you press play.

Core angle

Use AI to personalize what users see first—not only “more recommendations” buried below the fold.

What they do

• Personalized thumbnails and creative tests per user cluster.
• Ranking models that shape the majority of viewing time.
• Dynamic homepage composition based on taste and context.

Metrics impact

The objective function is watch time and churn reduction at scale—proxy metrics include starts per session, completion rates, and return frequency. Translate to stores as session depth, repeat orders, and subscription stickiness.

Actionable takeaway

Pick the first screen shoppers see after landing (homepage, collection, or post-click LP) and run a simple segment-based layout test. Measure revenue per session and repeat rate with our Ecommerce Simulator where relevant.
