Personalization

Signal-driven storefront experiences with ordered rules, payloads, targeting, rollout controls, and decision debugging.

Simple terms

Personalization chooses a visitor-specific experience from ordered rules and signals.

Signal-driven storefront experiences with ordered rules, payloads, targeting, rollout controls, and decision debugging.

Routes

  • /personalization

Implementation behavior

  • Personalization rules evaluate visitor and store signals in order and return the first eligible experience.
  • Experiences can use targeting, payload values, rollout percentage, and safe status controls.
  • Decision debugger shows matched and rejected rules so teams can understand runtime behavior.
  • The runtime uses the same event, segment, and signal foundation as experiments and flags.

How to use it

  • Create personalization only after the signal or audience is trustworthy.
  • Order specific rules above broad fallback rules.
  • Roll out gradually and inspect decisions before expanding traffic.
  • Use analytics and visitor trails to validate that the experience is reaching the intended group.

When not to use it

  • Do not use personalization when you need a clean randomized A/B test result.
  • Do not personalize from signals that are missing, noisy, or legally sensitive.
  • Do not create broad rules above specific rules unless the broad rule is meant to catch most traffic.

Implementation source

  • Pages live under src/app/(dashboard)/personalization.
  • Handlers live under /api/personalizations plus activate, pause, and archive routes.
  • Runtime decisions use segment, signal, rollout, and payload records tied to the active shop.

Data and API

  • Personalization, rule, payload, segment, signal, and decision records.
  • APIs under /api/personalizations, /api/personalizations/[id], /api/personalizations/[id]/activate, /api/personalizations/[id]/pause, and /api/personalizations/[id]/archive.
  • Uses SDK events, store facts, visitor context, and segment rules.

Failure modes

  • Wrong experience appears: rule order, broad targeting, or stale visitor signals.
  • No experience appears: paused status, rollout exclusion, missing signal, or targeting miss.
  • Hard-to-debug outcomes: use the decision debugger and visitor explorer together.
