Open Graph & Twitter Card Checker — Preview Social Sharing
Check Open Graph and Twitter Card tags on any URL. Preview how your content looks when shared on Facebook, X, and LinkedIn. Free OG tag checker.
What is an Open Graph & Twitter Checker?
The Open Graph and Twitter Card Checker fetches any URL and extracts all Open Graph (og:) and Twitter Card (twitter:) meta tags, then renders a live preview of how the URL will appear when shared on Facebook, LinkedIn, X, and other platforms that use these protocols. It shows missing required tags, incorrect image dimensions, and any tags that are present but likely to be overridden by platform defaults.
When Should You Use Open Graph & Twitter Checker?
Use this before sharing any important URL on social media — campaign landing pages, new blog posts, product announcements, or any page where the visual preview matters for click-through rate. A page with a missing og:image or a misconfigured Twitter Card will appear as a plain text link on social platforms, dramatically reducing engagement compared to a large image card. Run it after every site migration to confirm social metadata survived the move intact.
How to Read Open Graph & Twitter Checker Results
The preview shows exactly what users on each platform will see. Missing og:title and og:description cause the platform to pull from the page title and first paragraph instead — which may or may not be appropriate for the context. The recommended image size for most platforms is 1200×630px at a 1.91:1 aspect ratio. Images below 600px wide may not trigger a large card preview on some platforms, appearing as a small thumbnail instead.
What Should You Know Before Using Open Graph & Twitter Checker?
Set og:image, og:title, og:description, og:url, and og:type on every public page. For article pages use og:type of "article" and add article:published_time and article:author. For Twitter use twitter:card of "summary_large_image" for visual content. After updating social meta tags, use Facebook's Sharing Debugger and Twitter's Card Validator to force-refresh the cached preview for URLs that have already been shared — platforms cache social metadata aggressively and will not pick up changes automatically.
Frequently Asked Questions
What is Open Graph and why do I need it?
Open Graph (OG) is a protocol that controls how URLs appear when shared on social media platforms including Facebook, LinkedIn, and X. OG tags define the title, description, and image shown in the link preview. Without OG tags, platforms generate a preview from whatever content they parse first — often producing an unappealing or irrelevant result.
What is the correct size for an Open Graph image?
The recommended OG image size is 1200×630 pixels at a 1.91:1 aspect ratio. Images below 600px wide may not trigger a large card preview on some platforms, appearing as a small thumbnail instead. Use a high-quality, descriptive image that represents the page content — avoid logos-only images, which perform poorly for click-through rate on social sharing.
What is a Twitter Card?
A Twitter Card controls how URLs appear when shared on X (formerly Twitter). The summary_large_image card type displays a large image above the link description and is the most engaging format for content pages. Without a twitter:card tag, X displays only a small text preview. Add twitter:card, twitter:title, twitter:description, and twitter:image for full control.
How do I fix my Open Graph image not showing on social media?
First, use the OG and Twitter Checker to confirm your og:image tag is present and points to a valid, publicly accessible URL. If the image tag looks correct but social platforms still show the wrong preview, the issue is cached metadata — use Facebook's Sharing Debugger or Twitter's Card Validator to force the platform to re-scrape your page and update the cached preview.
Do Open Graph tags affect SEO?
OG tags do not directly influence Google search rankings. However, they significantly affect the appearance and click-through rate of your content when shared on social media, which drives traffic and engagement signals. Well-configured OG tags that generate compelling social previews result in more shares and clicks, which indirectly supports SEO through increased branded search and backlink acquisition.
