Image Not Showing
Symptoms
Shared links show a text-only preview without an image.
Causes
Missing og:image meta tag, image URL returns 404, image is too small (minimum 200×200 for most platforms), or CORS headers prevent the crawler from accessing it.
Solution
Add a proper og:image tag with an absolute URL. Ensure the image is accessible without authentication. Use dimensions of at least 1200×630.
Old/Wrong Preview Showing
Symptoms
The preview shows outdated title, description, or image even after updating.
Cause
Social platforms cache link previews aggressively (24-72 hours).
Solution
Use platform debugger tools to force a cache refresh. Facebook Sharing Debugger lets you 'Scrape Again'. For Twitter, re-fetching via Card Validator clears cache.
Title/Description Wrong
Cause
Platforms prioritize Open Graph tags over HTML title/meta description. If og:title is missing, they fall back to which may include site name suffixes.
Solution
Set both og:title and og:description explicitly for every shareable page. These can differ from the HTML title and meta description to be optimized for social sharing context.
