How social link previews actually work
When you paste a URL into a post, the platform doesn't read your page; it reads a handful of hidden meta tags in your HTML head. Open Graph tags (og:title, og:description, og:image) drive Facebook, LinkedIn and most others, while X reads its own twitter:card tags first and falls back to Open Graph. A previewer pulls those exact tags and renders the card a scraper would build. The thing most people miss: platforms cache aggressively, so a fix you make today often won't show until you force a re-scrape through the platform's own debugger.
Link preview tips
- Set og:image to at least 1200x630 pixels; smaller images often render as a tiny thumbnail instead of a full card.
- X needs twitter:card set to summary_large_image for the big image; without it you get the cramped square-thumbnail layout.
- Keep og:title under about 60 characters and og:description near 110, since platforms truncate the rest with an ellipsis.
- Previewers show cached data, so always confirm changes in the platform's own debugger, which forces a fresh scrape of your tags.

Link Previewer for Social Media — common questions
Latest questions readers ask us about this topic.
Why does my link preview show the wrong image or old text?
Platforms cache scraped Open Graph data for days or weeks. After updating your meta tags, run the URL through the platform's official debugger or sharing tool to force a re-scrape and refresh the cached preview.
What meta tags control a social media link preview?
Open Graph tags do most of the work: og:title, og:description, og:image and og:url. X also reads twitter:card, twitter:title and twitter:image, falling back to Open Graph when those Twitter-specific tags are absent from the page head.
What image size should I use for link previews?
Use 1200x630 pixels, a 1.91:1 ratio, for the large card that Facebook, LinkedIn and X share. Keep the file under roughly 5MB and avoid tiny text, since the image is often scaled down in feeds.
