Merchant-safe CSS checklist for controlled Shopping growth.

Use this checklist to evaluate whether extra Shopping reach can run beside your existing campaigns while protecting merchant rules and measurement quality.

Boundary

Existing campaigns stay protected.

The partner should explain how merchant-owned and agency-owned campaigns remain visible, measurable and outside the replacement path.

Signal

Feed and product readiness come first.

Products should only move when attributes, titles, shipping, availability, policy and commercial value support activation.

Proof

Every click needs a readable trail.

Traffic origin, product linkage, decision history and conversion context should be available for review.

Governance

Humans approve commercial movement.

AI can score and recommend, but operators should approve scale, hold, pause and fix-first actions.

Incrementality

The growth story must be complementary.

A safe growth layer should show where extra coverage is likely and where overlap or weak value makes scaling unsafe.

Outcome

Reports should explain the decision.

The final output should show baseline, signal, action, guardrail, outcome and learning loop.

Turn the guide into a scoped decision path.

Share your market, feed and campaign context so ShopSailor can show what should scale, hold or be fixed first.
