Preview social metadata with absolute, public assets
Practical example
An og:image path that works in a logged-in browser can fail for a social crawler if it is relative, blocked or requires cookies. Use an absolute HTTPS image URL and test it publicly.
Interpreting the result
Align title, description, canonical page and image with the shared content. Check image dimensions, file size, MIME type and cache refresh behavior on each target platform.
Limits and common mistakes
Platforms can crop, rewrite or cache previews and may use different fallback tags. A markup check cannot guarantee the final appearance or force a platform to refresh immediately.
