Frequently asked questions
Why does Facebook show the wrong image?
Facebook caches previews. Fix og:image, then use Facebook's Sharing Debugger to scrape the URL again.
What are Open Graph tags?
Meta tags (og:title, og:description, og:image) that tell social networks what to show for a link.
Do I need Twitter Card tags?
X falls back to Open Graph, but twitter:card=summary_large_image gives the big image layout.
