Question 1

Why does my link look different on different platforms?

Accepted Answer

Each platform reads Open Graph tags differently. Facebook and LinkedIn use og:title, og:description and og:image. X uses twitter:title and twitter:image if present, falling back to og: tags. WhatsApp uses og: tags only. Each platform also has different image aspect ratio preferences and character limits for title/description truncation.

Question 2

Why is my og:image not showing on Facebook?

Accepted Answer

Common reasons: the image URL is not publicly accessible, the image is smaller than 200x200px (minimum for Facebook), the server returns incorrect content-type headers, or Facebook's cache is showing an old version. Use the Facebook Sharing Debugger to scrape fresh data and clear the cache.

Question 3

How do I update my social preview after changing OG tags?

Accepted Answer

Facebook and LinkedIn cache social previews aggressively. Use the Facebook Sharing Debugger (developers.facebook.com/tools/debug) to force a fresh scrape. For LinkedIn, use the Post Inspector (linkedin.com/post-inspector). Twitter/X typically refreshes within 24 hours automatically.
