For: Headless Shopify Plus E-Commerce ArchitectureThe Speed-to-Revenue Equation in E-Commerce
Performance can affect e-commerce behavior, but there is no universal conversion loss for every 100 milliseconds. The effect varies by audience, device, journey, traffic source, and implementation. Standard Shopify themes may accumulate costly scripts, but this should be established with page-level profiling.
Headless Shopify Plus changes the performance architecture; it does not remove performance work.

Headless can help when a brand needs unusual experience design, complex integrations, or independent frontend release cycles. It also adds cost and operational complexity.
