Is headless worth it?
Headless when your conversion ceiling is capped by theme performance or UX limits, or when you sell across multiple surfaces. Themes when traffic is under ~500k monthly sessions and the theme handles your merchandising cleanly. We settle the question in 20 minutes during the scoping call.
AI features that move ecommerce numbers
All four are in scope.
- AI-powered product search that handles natural-language queries.
- AI recommendations that respect dwell time and add-to-cart history.
- AI-generated PDP copy at scale.
- AI customer-support agents that handle order-status, returns, and sizing before a human picks up the chat.
Conversion principles we build to
- Sub-1-second LCP on every PDP hero — roughly 3x conversion lift vs. 3-second pages (Google CrUX 2026).
- Single primary CTA above the fold. Add-to-cart is the only action.
- Sticky mobile cart with running total.
- Multi-step checkout with email first, then address and payment.
- Exit-intent recovery modal on desktop with a soft offer.
- Trust signals above the fold — reviews count, years selling, payment-method badges.
- Pricing always visible. No 'log in to see price' patterns except B2B trade.
