FAQ
Does Twitter ignore og: tags?
No — Twitter falls back to og:title / og:description / og:image when the Twitter-specific tags are absent. Adding twitter:card alone is usually enough.
Why is my preview not refreshing?
Facebook and LinkedIn cache previews aggressively. Use the Facebook Sharing Debugger and LinkedIn Post Inspector to force a refresh after updating tags.
