Open Graph
Open Graph Protocol
A set of meta tags controlling how pages appear when shared on social media (title, description, image).
Detalle técnico
Open Graph 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.
