Begin with a signal map that documents what data is trustworthy, its freshness, and its owner. Spin up lightweight agents for discovery, merchandising, and checkout that can only act within pre-approved charters. Each charter includes allowed actions, prohibited actions, KPI, and rollback triggers. Start with a discovery agent that can reorder collections and recommendations, then layer a checkout concierge that adjusts incentives within a safe margin band.

Unify zero-party data (quiz answers, preference captures) with behavioral scores and inventory so the AI can propose the right SKU in two steps. Precompute micro-segments such as high-margin urgency shoppers or replenishment buyers. Allow the AI to personalize hierarchy: hero copy, bundles, payment order, and delivery promises. Measure success by win rate versus static variants and profit per session, not only conversion.

Publish speakable schema, keep a library of pre-approved product claims, and cache inventory-safe offers so responses stay under one second. Route high-intent voice sessions to an autonomous cart builder that can prefill items, propose payment plans, and hand off to humans when risk or trust thresholds are hit. Track voice-to-cart completion, latency, and abandonment as core CRO metrics.

Define a brand and compliance style guide for every AI surface: tone, claims, disallowed phrases, and regulated categories. Add business guardrails (margin floors, inventory buffers), technical guardrails (latency ceilings, rate limits), and human guardrails (override policies). Keep immutable audit trails that log prompts, data inputs, outputs, and overrides with timestamps and owner IDs.

Use question-first tests tied to business KPIs instead of random copy tweaks. Limit concurrent experiments per surface so attribution stays clear. Require every AI-led test to ship with an experiment ID synced to GA4, CDP, and the orchestration layer. Report lift, variance, time-to-confidence, and manual hours saved. Promote winners to a guarded automation mode that can self-tune within defined ranges.

Days 0-30: clean analytics, map signals, and launch a discovery agent on limited traffic. Days 31-60: expand to cart and checkout incentives with hard margin guardrails, wire audit logs, and measure override rate. Days 61-90: introduce voice and post-purchase retention automations, set executive dashboards, and rehearse kill-switch drills.
