Vad är Schema Markup Structured

Schema markup (structured data) is code added to a website's HTML to describe content in a standardized format that search engines, voice assistants, and other bots understand. The most common formats are JSON-LD, Microdata, and RDFa. Schema.org provides a shared vocabulary, you mark up a product with properties like name, price, availability, rating, and Google can then display a rich snippet directly in search results. Schema markup is invisible to users but transforms plain-text search results into interactive cards. An e-commerce site selling shoes might markup a product with JSON-LD; Google shows the product image, price, star rating, and "Add to Cart" button right in the SERP, increasing click-through rate dramatically.

❓ Vanliga frågor

Why does schema markup matter for SEO?
Schema markup creates rich snippets (star ratings, prices, availability) that increase click-through rate. It also helps Google's AI understand content nuance, improving ranking relevance and featured snippet eligibility.
JSON-LD vs Microdata: which should I use?
JSON-LD is preferred by Google and easier to maintain, it lives in `<script>` tags and doesn't require attributes on HTML. Microdata embeds in HTML attributes; use only if you can't modify the template layer.
How do I validate my schema markup?
Use Google's Rich Results Test (console.google.com), Schema.org Validator, or Screaming Frog. Check structured data appears in PageSpeed Insights and Search Console's Rich Results reports.
Can I use schema markup on dynamic content (SPAs, React)?
Yes. With client-side rendering, inject JSON-LD in the `<head>` via React effect before hydration, or use server-side rendering (Next.js) to render schema at build time. Verify with Rich Results Test.
What's the ROI of adding schema markup?
Rich snippets lift CTR by 20–30% on branded queries. For e-commerce, product schema enables Shopping carousel eligibility. For news/articles, NewsArticle schema increases discoverability by 10–15%.
