What is schema markup and do you need it?

Schema markup is structured data — a vocabulary (schema.org) that tags content with meaning. A product page without schema tells Google ‘here are some words.’ With Product schema, it tells Google ‘this is a product named X, priced $Y, in stock.’ Search engines use schema to generate rich results: star ratings, prices, FAQ accordions, breadcrumbs, and more. These rich results get more clicks than plain blue links.

Schema can be implemented in microdata, RDFa, or JSON-LD. Google strongly recommends JSON-LD — it’s cleaner, easier to maintain, and separated from HTML. Add JSON-LD in a `<script type="application/ld+json">` block in the page head or body. Use Google’s structured-data generators or write it directly. Every major CMS (Next.js, WordPress, Shopify) supports JSON-LD injection via plugins or code.

Organization: your business identity (name, logo, URL, sameAs social profiles). BreadcrumbList: navigation context on every inner page. WebSite: with potential SearchAction for sitelinks search box. These three go site-wide. Beyond that: Article on blog posts, Product on product pages, FAQPage on FAQ sections, LocalBusiness if you have a physical location, Recipe for food, Event for events. Pick what’s relevant — don’t force schema that doesn’t fit.

FAQ schema earns expandable FAQ snippets in search results — high-CTR real estate. Use it on genuine FAQ sections, not marketing Q&As. Each question must exist visibly on the page (not hidden). Each answer should be 30–100 words, plain text, no markdown. Don’t stack 20 FAQs on every page — Google limits the snippet to 2–4 questions shown. Put the questions you most want visible first.

Product schema is mandatory for ecommerce SEO. Required fields: name, image, description, brand, sku. Strongly recommended: aggregateRating (stars!), review (individual reviews), offers (price, priceCurrency, availability). Avoid: inflating review counts, showing prices you don’t actually charge, marking out-of-stock items as in-stock. Google suspends rich results for deceptive schema — and the suspension applies site-wide, not per page.

Use Google’s Rich Results Test (search.google.com/test/rich-results) to validate schema and preview rich snippets. Then check Search Console → Enhancements for ongoing issues. Schema rich results don’t appear immediately — it takes Google 2–8 weeks to re-crawl and start displaying. Don’t panic if rich snippets don’t show the day after implementation; monitor for 30 days before concluding something’s wrong.
