How the Open Graph Checker Works

This tool fetches any webpage and extracts all social sharing metadata. Here's the process:

  1. Enter a URL — paste any page address. The tool fetches the full HTML just like a social media crawler would.
  2. Tag extraction — it reads all Open Graph tags (og:title, og:description, og:image, etc.), Twitter Card tags, and standard meta tags.
  3. Platform previews — see visual mockups of how your link will appear on Google, Facebook, X/Twitter, LinkedIn, Discord, and WhatsApp.
  4. Score and issues — get a quality score (0–100) plus specific flags for missing or problematic tags.

Why Open Graph Tags Matter

Every time someone shares a link — on social media, in a group chat, on Slack, or in an email client that renders previews — the platform reads your OG tags to build the preview card. Without them, you're leaving first impressions to chance.

  • Click-through rates — links with a compelling image, title, and description get significantly more clicks than plain URLs or auto-generated previews.
  • Brand consistency — OG tags let you control exactly what appears. No more random images pulled from your sidebar or footer.
  • Cross-platform reach — Facebook, X, LinkedIn, Discord, WhatsApp, Slack, Telegram, and iMessage all use OG tags. One set of tags covers almost every sharing surface.
  • GEO and AI visibility — AI search engines display rich cards when citing sources. Well-structured metadata helps your content stand out in AI-generated answers.

For the full technical picture, pair this with the SSL Certificate Checker (HTTPS is required for OG images on most platforms) and the Robots.txt Tester to make sure crawlers can actually access your pages. After OG tags, check your schema markup — structured data gives you even richer signals to search engines and AI. Preview the full Google search result with the SERP Preview Simulator.

Essential Open Graph Tags for Every Page

Not sure which tags to add? Here's the minimum set every page should have:

  • og:title — the title shown in link previews. Keep it under 60–70 characters for best display.
  • og:description — a short summary. 100–160 characters works well across platforms.
  • og:image — the preview image. Use 1200×630px for universal compatibility. This is the single most impactful tag for engagement.
  • og:url — the canonical URL of the page. Helps platforms consolidate share counts.
  • og:type — usually website for homepages and article for blog posts.
  • twitter:card — set to summary_large_image for large image previews on X/Twitter, or summary for smaller ones.

These tags work together with your SEO setup — they share the same content strategy but serve different surfaces.

Open Graph Checker: FAQ

What are Open Graph meta tags?
Open Graph (OG) meta tags are HTML tags that control how your page looks when shared on social media. They define the title, description, image, and URL that platforms like Facebook, LinkedIn, Discord, and WhatsApp display in link previews. Without OG tags, platforms guess what to show — and they usually guess poorly.
What does this Open Graph checker do?
This tool fetches any webpage, extracts all Open Graph and Twitter Card meta tags, shows you exactly what each platform will display, calculates a quality score, and flags missing or problematic tags. It also pulls standard meta tags like title, description, canonical, and robots.
What is a Twitter Card and how is it different from Open Graph?
Twitter Cards (now X Cards) are meta tags specific to Twitter/X that control link previews on that platform. The main tag is twitter:card which sets the card type (summary or summary_large_image). Twitter also reads OG tags as fallback, so if you have OG tags but no Twitter Card tags, your links will still preview — just without Twitter-specific optimizations.
What OG tags should every page have?
At minimum: og:title, og:description, og:image, og:url, and og:type. The image is especially important — links without an og:image get significantly less engagement on every platform. For Twitter/X, also add twitter:card with a value of summary_large_image for the best visual impact.
What is the ideal og:image size?
The recommended size is 1200×630 pixels. This works well across Facebook, LinkedIn, Twitter/X (summary_large_image), Discord, WhatsApp, and Slack. Keep the file size under 5MB. Use JPG or PNG format. Avoid text-heavy images since they may be cropped differently on each platform.
Why does my link preview look wrong on Facebook?
Facebook caches OG data aggressively. If you recently changed your OG tags, the old preview may still show. Use Facebook's Sharing Debugger (developers.facebook.com/tools/debug) to clear the cache. Also check that your og:image URL is publicly accessible — Facebook cannot read images behind authentication or localhost.
Do OG tags affect SEO?
Not directly — Google does not use OG tags as ranking signals. But indirectly, yes. Better link previews lead to higher click-through rates on social media, more shares, and more traffic. OG tags also help control how your pages appear in messaging apps and platforms that feed into broader visibility.
Is this Open Graph checker free?
Yes. This tool is completely free with no signup, no limits, and no ads. Built for website owners, developers, marketers, and agencies.
Does this tool store the URLs I check?
No. The tool fetches the page, extracts the tags, and returns the result. We do not store URLs, page content, or personal data.
