The challenge

A mid-premium jewelry brand sells $325 gifts but shoppers hesitate over materials, sizing, authenticity, and delivery timing.

What WKND built

Ad groups by buyer question: Gift occasions (40% or $18,000); Materials and craftsmanship (35% or $15,750); Style and sizing comparison (25% or $11,250).

Landing page

Use occasion-specific collections that link to detailed product pages. Show material composition, dimensions, care, guarantees actually offered, delivery cutoff, and returns. Avoid vague premium claims when a clear close-up or measurement will answer the question.

Intake and follow-up

Send product-specific reminders and buying guidance with consent. Capture gift occasion only if the customer volunteers it and use it responsibly. Later gifting or accessory offers are modeled separately, with initial purchases and refunds fully reconciled first.

The lesson

Premium order value and contribution margin must support the actual cost per order after the budget increase. The case includes refunds, program costs, and later repeat value so revenue growth does not conceal declining acquisition efficiency.
