Amazon's product discovery experience is renowned for how many ways they target customers psychologically. From visually prominent urgency cues to default recurrence of past behaviours, the experience is heavily optimised to shift users from casual scrolls to considered actions.

Personalised content blocks and filtering mechanisms scaffold user motivation, but also introduce cognitive noise, especially when persuasive elements are overstacked without context.

The flows we reviewed

sentiment_very_satisfied

What works

  • Clear and persistent visual anchors (e.g. sticky filters, bundle pricing) guide users toward action
  • Social validation is seamlessly embedded through viewer counts, ratings and recommendations
  • Use of urgency (limited time deals) and scarcity (low availability) stimulates conversion
  • Personalised repeat purchase nudges reduce effort and increase relevance
  • Comparison-framed modules (e.g. highest rated vs lowest price) support choice confidence
sentiment_sad

What doesn't work

  • Ambiguous labels like "recent trends" lack clarity on peer group or logic behind suggestions
  • Sponsored content blends too closely with genuine recommendations, risking trust erosion
  • Repeated modules across different screens may cause fatigue or distraction
  • Filters and list mechanics assume user intent without offering sufficient customisation
