Why is my Facebook link preview image not showing up?

Facebook caches Open Graph data. If you recently updated your og:image or meta tags, you must use Facebook's Sharing Debugger to clear their crawler cache and scrape the new image.

What is the recommended Facebook link preview image size?

The recommended size is 1200 x 630 pixels with an aspect ratio of 1.91:1. This guarantees crisp rendering without cropping on desktop newsfeeds and high-DPI mobile devices.

Why Test Facebook Link Previews Before Publishing?

Facebook generates post previews by reading your website's og:title, og:image, and og:description tags. If tags are missing or improperly sized, Facebook will render a tiny, blurry thumbnail or fail to display an image at all, slashing your organic click-through rate by up to 75%.

Facebook Link Sharing Best Practices

1.91:1 Aspect Ratio: Standard 1200 × 630 px guarantees your preview renders as a full-width desktop and mobile banner.
Punchy Titles: Keep your card headline under 60 characters to prevent truncation on mobile feed cards.
Clear Facebook Cache: Use Facebook's official Sharing Debugger whenever you update Open Graph metadata.
