What you need to know
Social preview metadata gives people context before they click. A relevant title and image can make a link easier to recognize and share, while mismatched metadata can make a trustworthy page look broken.
How to apply it
Provide Open Graph title, description, URL, type, and an absolute image URL. Use a specific preview for important pages, and validate it after publishing because crawlers may cache old previews.
Common mistake to avoid
Do not copy one generic title and description across every route. Each public page should describe its own content accurately.
