Schema Markup
Schema.org Structured Data
A vocabulary of tags added to HTML to help search engines understand page content and display rich results.
Detalle técnico
Schema Markup directly influences click-through rates from search results. Google typically displays the first 50-60 characters of a title tag and 150-160 characters of a meta description, though it may rewrite descriptions based on query relevance. Each page should have a unique title containing primary keywords near the beginning. The meta description acts as ad copy — it doesn't directly affect rankings but affects whether users click. Open Graph (og:) and Twitter Card meta tags control social media previews separately from search results.
