Metafields are custom data fields attached to Shopify resources — products, collections, pages, customers. They store structured information the standard fields don’t cover (ingredients, size charts, care instructions) and render in themes via dynamic sources.
For SEO, metafields enable scaled unique content: store per-collection FAQ text or specification tables in metafields and render them in templates, giving every page distinct, indexable content.
Liquid is Shopify’s open-source templating language, used in all themes to render dynamic content with objects ({{ product.title }}), tags ({% if %}), and filters (| money). Understanding basic Liquid lets merchants customize themes without a developer.
A collection page is a Shopify category page that groups related products — for example /collections/summer-dresses. Collection pages are the highest-traffic-potential pages on most stores because they match commercial search queries like "linen summer dresses" better than individual products do.
Structured data is information formatted in a standardized, machine-readable way — on the web, usually schema.org vocabulary expressed as JSON-LD. It lets search engines and LLMs parse facts (prices, ratings, authors) without guessing from prose.
