The wrong reason

Do not choose headless because the current site looks dated. A strong platform-native rebuild can still be the better business decision.

The right reason

Use headless when the public storefront needs a different model: richer editorial pages, strict speed and SEO control, better product presentation, or cleaner long-term maintenance.

The test

Before building, name what each system owns: storefront, CMS, products, checkout, customer state, schema, analytics, Cloudflare, deployment, and support.
