Headless CMS for E-commerce: Architecture, Stack, SEO and Cost
Headless CMS + Next.js for online stores: Strapi, Sanity, Contentful, Shopify Storefront API. E-commerce SEO, SSG/ISR, ERP sync, Stripe. When headless pays off.
Classic online stores on WooCommerce or OpenCart hit limits: slow pages, weak SEO, limited UX and hard ERP integration. Headless e-commerce separates storefront (frontend) from backend (catalog, orders, payments, CMS) for full control over speed, SEO optimization and user experience.
What is headless e-commerce
| Layer | Tasks | Tech |
|---|---|---|
| Frontend | UI, UX, SEO, Core Web Vitals | Next.js, React |
| Commerce backend | Catalog, cart, orders, inventory | Medusa, Saleor, custom API |
| Headless CMS | Blog, landings, SEO copy | Strapi, Sanity, Contentful |
| Payments | Checkout, receipts | Stripe, YooKassa |
| Integrations | ERP, CRM, marketplaces | REST/GraphQL |

- Tight budget (< $2,500)
- Template UX is enough
Start monolith with API migration path.
