Frequently asked
Why does my shared link have no image?
Almost always a missing or non-absolute og:image tag. The image URL must be absolute (https://...) and reachable by the scraper.
Do I need both Open Graph and Twitter tags?
Open Graph covers Facebook, LinkedIn, and (as a fallback) Twitter/X. Add twitter:card to control the X presentation specifically.
