OpenGraph Preview
See exactly how any URL looks when shared on Twitter/X, LinkedIn, and Facebook. Inspect every OG and Twitter Card meta tag your page is sending.
Why OpenGraph tags matter
When someone shares your URL on social media, the platform fetches your page and reads the og:title, og:description, og:image, and og:site_name meta tags to build the preview card. Without these tags, platforms fall back to guessing — often picking the wrong image or showing a blank card with just the URL. A compelling OG image and title can double the click-through rate on shared links.
Twitter uses its own set of meta tags (twitter:card, twitter:title, twitter:description, twitter:image) but falls back to OG tags if the Twitter-specific ones are absent. Adding twitter:card with a value of summary_large_image enables the big image format — the one that takes up most of the tweet. Without it, you get a small thumbnail or no image at all.
OG images should be 1200x630 pixels (1.91:1 ratio) for best compatibility across all platforms. LinkedIn caches previews aggressively — use their Post Inspector tool to force a re-scrape after you update your tags. Facebook similarly caches for 24 hours unless you submit the URL to their Sharing Debugger. This tool fetches live, so it always shows your current tags without cache interference.
