How to Preview Social Media Link Cards Before Publishing
Why Preview Matters
A poorly formatted link card — wrong image, truncated title, missing description — can reduce click-through rates by 30–50%. Since social platforms cache previews aggressively, a bad first impression can persist for hours after you fix the underlying tags.
How OG Preview Tools Work
OG preview tools fetch the target URL, parse Open Graph and Twitter Card meta tags, and render a simulation of how each platform will display the link. Some tools also check image dimensions, load times, and tag validity — flagging problems before they reach users.
Platform-Specific Differences
Facebook and LinkedIn read og: tags similarly but have different image cropping behaviors. Twitter applies its own twitter: tags but falls back to og: tags when twitter: tags are absent. Slack and Discord read og: tags and typically show a compact version. Testing across all four surfaces prevents surprises.
