Reference guide

Every OG tag
explained

Open Graph protocol tags control how your content appears across every major social platform. Missing or misconfigured tags can cut click-through rates by up to 40%.

Full OG guide
og:title
Required

The title of your content as it should appear in the social card. Overrides the HTML <title> tag on social platforms.

<meta property="og:title" content="Your Article Title Here" />
Keep under 60 characters. Facebook truncates at ~65 chars; Twitter at ~70 chars. Test different titles for different platforms using og:title vs twitter:title.
og:description
Required

A short description of your content shown below the title in link cards. Should be unique and compelling - this is your 160-character sales pitch.

<meta property="og:description" content="Your compelling description..." />
Aim for 120–160 characters. Avoid duplicating the title. Facebook shows ~300 chars but only ~2 lines are visible above the fold.
og:image
Required

The thumbnail image that dominates the link card. This is the single biggest factor in whether someone clicks your shared link.

<meta property="og:image" content="https://example.com/og-image.png" />
Minimum size: 1200×630px. Must be an absolute URL (https://). Images under 600×315px may not generate a card at all. Max file size: 8MB.
twitter:card
Recommended

Controls the layout of X/Twitter link cards. summary_large_image shows a large hero image. Without it, Twitter falls back to og: tags.

<meta name="twitter:card" content="summary_large_image" />
Values: summary, summary_large_image, app, player. Use summary_large_image for articles and blog posts to maximize click-through.
og:image:width / og:image:height
Optional

Explicit image dimensions allow social crawlers to display the image without needing to download it first. This speeds up link card rendering significantly.

<meta property="og:image:width" content="1200" />
<meta property="og:image:height" content="630" />
Always provide these alongside og:image. Crawlers will display cards faster since they can allocate space without downloading the image first.

Why this matters

The business case for
perfect link previews

Bad OG tags aren't a minor detail. They directly impact how much traffic you get from every link you share.

3×

More clicks with og:image

Social posts with a large preview image receive up to 3× more clicks than plain text link posts. Missing your og:image is the single most costly OG mistake.

Hootsuite Social Media Research, 2024
40%

CTR drop from missing tags

Pages without properly configured Open Graph tags see an average 40% lower click-through rate when shared on Facebook and LinkedIn compared to pages with complete OG data.

Everything you need to know about Open Graph tags, social sharing previews, and how to fix them.

Ask a question
A link preview is the card that appears when you paste a URL on Facebook, X, LinkedIn, or in iMessage. It shows a title, description, and image pulled from the page's Open Graph meta tags. Without these tags, platforms either show no card or generate a generic, often ugly, fallback.
The tool extracts and validates: og:title, og:description, og:image, og:url, og:type, og:site_name, og:locale, og:image:width, og:image:height, twitter:card, twitter:title, twitter:description, twitter:image, canonical, and standard <title> plus meta name="description".
Facebook's Sharing Debugger only shows Facebook's cached view of a page and only simulates one platform. Our tool shows previews for 6 platforms simultaneously - Facebook, X/Twitter, LinkedIn, WhatsApp, iMessage, and Google Search - with live extraction and no cache lag.
Each platform has different specs and uses a slightly different priority order for fallback tags. Twitter reads twitter: tags first, then falls back to og: tags. LinkedIn and Facebook both use og: tags but crop and truncate text at different lengths. Google ignores OG entirely and uses <title> and meta description. This tool shows you all six at once.
The most common causes: the image URL is relative (not absolute with https://), the image is smaller than 600×315px, the image returns a redirect, the image URL is blocked from external crawlers, or the platform has a stale cached version. Use this tool to see exactly what the crawlers see, then use the platform's debugger to force a cache refresh.
The gold standard is 1200×630px (1.91:1 ratio). This works across Facebook, LinkedIn, WhatsApp, and iMessage without cropping. Twitter uses a 2:1 ratio, so 1200×600px is the closest universal compromise. Always specify og:image:width and og:image:height alongside the image URL to speed up card rendering.
The extractor needs to fetch the page over the internet, so it requires a publicly accessible URL. For staging environments behind basic auth or VPNs, you'll need to temporarily whitelist the extractor's requests or test on a public staging URL. You can also manually input tag values in the decoder section to preview them.
