What Shopify Optimisation Should Fix First

What Is Structured Data and Schema?
Structured data adds machine-readable context to content so search engines can display rich results like product snippets, FAQs, and event cards. Schema.org markup (JSON-LD preferred) supports entities such as Organization, Product, BreadcrumbList, and Review, improving CTR and discoverability.

Is migrating to a new theme necessary for optimisation?
Not always, but migrating to a modern, well-coded theme (OS 2.0/Dawn) often reduces client-side JavaScript and improves render performance. If the current theme is heavily customized or legacy, a refactor may be the cleaner long-term solution.

Related Concepts and Subtopics
Adjacent topics that influence prioritisation include headless/Shopify Hydrogen approaches, app governance, and analytics instrumentation. These decisions affect developer effort and long-term agility, so evaluate them after primary fixes are complete.
