About Open Graph Checker

An open graph checker scans any URL and pulls out the OG meta tags that control how your links look when shared on Facebook, LinkedIn, X (Twitter), and messaging apps like WhatsApp. ToolsPivot's Open Graph Checker validates tag values, flags missing properties, and shows a real-time preview of your social share card, all without sign-up or usage caps.

How to Use ToolsPivot's Open Graph Checker

Paste your URL: Copy the full address of the page you want to check and drop it into the input field on the ToolsPivot Open Graph Checker page.
Click "Check": The tool fetches your page's HTML, scans the section, and extracts every OG meta tag it finds.
Review the tag list: You'll see each detected property (og:title, og:description, og:image, og:url, og:type, og:site_name, og:locale) with its current value displayed in a clear table.
Check the preview: A visual mockup shows how your link will appear on Facebook and X feeds. Compare the preview against your intended headline and thumbnail.
Fix flagged issues: Any missing or misconfigured tags are highlighted. The tool provides ready-to-copy HTML code for tags you need to add to your page's section.

The whole process takes about 5 seconds. Run it again after making changes to confirm everything looks right before you share.

What ToolsPivot's Open Graph Checker Does

Full tag extraction: Pulls og:title, og:description, og:image, og:url, og:type, og:site_name, and og:locale from any public URL. You see exactly what social platforms will read when someone shares your link.
Visual share preview: Generates a realistic mockup of how your link card will look on Facebook feeds and X timelines. No need to actually post a link just to see the result.
Missing tag alerts: Flags which required OG properties are absent. The Open Graph Protocol defines four required tags (og:title, og:type, og:image, og:url), and this checker tells you if any are missing.
Character length validation: Warns you when og:title exceeds 60 characters or og:description runs past 160 characters, since both get truncated on most platforms.
Image dimension check: Verifies whether og:image meets the recommended 1200x630 pixel size. Images below 600x315 pixels may not display at all on Facebook.
Code generation: Produces copy-ready HTML meta tags for any properties your page is missing. Paste the code into your section and you're done.
Twitter Card detection: Identifies whether twitter:card, twitter:title, and twitter:image tags exist alongside your OG tags. If they don't, the tool flags it so you can generate Twitter Card tags separately.
Protocol compliance scoring: Checks your implementation against the official Open Graph Protocol spec (ogp.me) maintained by Facebook. You'll know right away if your tags follow the standard or not.

Benefits of ToolsPivot's Open Graph Checker

No sign-up, no limits: Check as many URLs as you want. There's no account creation, no daily cap, and no paywall hiding features behind a subscription. Most competing OG checkers (like Sitechecker or OpenGraph.xyz premium features) require registration or restrict free usage.
Catch broken previews before they go live: A shared link with a missing image or a truncated title looks unprofessional. One check before publishing saves you from that. Studies suggest that well-formatted social previews can boost click-through rates by up to 40% compared to links with generic or blank cards.
Faster debugging: Instead of posting a test link on Facebook, waiting for it to render, realizing the image is wrong, editing the tag, and clearing the cache, you can spot every issue in a single scan. Pair it with ToolsPivot's Open Graph Generator to create corrected tags instantly.
Works for any public URL: WordPress blogs, Shopify product pages, custom-coded sites, Wix landing pages, static HTML files. If the page is publicly accessible, the checker can scan it.
Full metadata context: Beyond OG tags, you'll also see the page's standard meta title and meta tag data, giving you a fuller picture of how search engines and social platforms interpret your page.
Spot competitor strategies: Paste any competitor's URL and see exactly which OG tags they've set. That's free competitive intelligence. Run their page through the meta tag generator too if you want to see how your own tags stack up.

Reading Your OG Checker Report

The results page breaks down into three parts, and each one tells you something different about your page's social sharing readiness.

The tag table lists every OG property found in your HTML. Green values mean the tag exists and passes validation. If a tag is present but the value is too long, the tool flags it in yellow. Missing required tags show up in red. Focus on the red items first.

The four required OG tags per the Open Graph Protocol are og:title, og:type, og:image, and og:url. If any of these are missing, social platforms will either guess (and often guess wrong) or display a blank card. Facebook, for example, may pull a random image from the page if og:image isn't set. That random image might be a site logo, an ad banner, or nothing at all.

The preview card shows a visual mockup of your shared link. Compare the displayed title, description, and image against what you actually want people to see. If the preview doesn't match your expectations, the tag table tells you exactly why. Maybe your og:image URL is pointing to an old file or a placeholder.

The code output gives you HTML you can copy and paste. If you're running WordPress with Yoast SEO or Rank Math, you can paste these values into the plugin's social tab instead. Shopify stores can edit OG tags through the theme's theme.liquid file or use a dedicated SEO app.

Fixing the Most Common OG Tag Problems

After scanning hundreds of URLs, certain mistakes come up again and again. Here's what to look for and how to fix each one.

No og:image at all. This is the single biggest issue. Links shared without an image tag display as plain text on Facebook and LinkedIn. The fix is straightforward: add a meta tag pointing to a high-quality image. Use 1200x630 pixels as your default size. If your images are too large, run them through an image compressor to keep the file under 1MB.

Image is too small. Facebook won't render images under 200x200 pixels, and anything below 600x315 gets displayed as a tiny thumbnail instead of a large card. You can resize your image to the recommended dimensions before setting it as your og:image.

Using relative URLs for og:image. An image path like /images/hero.jpg works in a browser, but social platform crawlers sometimes can't resolve it. Always use the full absolute URL: https://yourdomain.com/images/hero.jpg.

Title too long or too vague. Titles exceeding 60 characters get chopped with an ellipsis. And generic titles like "Home" or "Untitled" waste the strongest real estate on your share card. Write a concise, specific title. If you need help crafting one, try the AI meta title generator as a starting point.

Stale cached data. You fixed your tags, ran the checker again, and everything looks good. But when you share on Facebook, the old image still shows up. That's because Facebook caches OG data the first time someone shares your URL. Use the Facebook Sharing Debugger to force a re-scrape, and LinkedIn's Post Inspector for the same purpose on LinkedIn.

Mixed HTTP/HTTPS. If your site uses HTTPS but your og:image URL starts with HTTP, some platforms will block the image entirely due to mixed content rules. Double-check that every URL in your OG tags uses https://.

Who Needs an OG Tag Checker (And When)

If you share links on social media, run ads that link to web pages, or manage a site where other people share your content, you need OG validation. But some situations make it especially critical.

Before launching ad campaigns. Facebook and LinkedIn ads pull preview data directly from OG tags. Running a $5,000 ad campaign with a broken preview image is an expensive mistake. Marketers at agencies handling multiple client accounts run OG checks on every landing page before campaign launch.

After CMS updates or theme changes. A WordPress theme update or a Shopify template switch can silently break your OG tag output. One day your social cards look perfect; the next, they're blank. A quick check with ToolsPivot's tool catches this before your audience does. Combine it with a full website SEO audit to catch other technical issues at the same time.

E-commerce product launches. When you're about to promote a new product on Instagram, Facebook Groups, or Pinterest, you want the share card to show the right product image, the right title with the product name, and a description that includes the price or key feature. Retailers who validate OG tags on product pages before promotion see more consistent branding across channels.

Content distribution workflows. Blog editors and SEO professionals who publish 5 to 20 articles per week often add OG checking into their publish checklist, right between "run the readability checker" and "submit to Google Search Console." It takes 10 seconds per article and prevents bad social previews from reaching hundreds of thousands of followers.

How Social Platforms Use OG Tags Differently

Every major platform reads OG tags, but each one has quirks worth knowing about.

Facebook is the original home of the Open Graph Protocol. It recognizes all standard OG properties and caches them aggressively. Minimum image size is 600x315 pixels; the recommended size is 1200x630 pixels for a 1.91:1 aspect ratio. Use the Facebook Sharing Debugger to clear the cache after making any changes to your tags.

X (Twitter) falls back to OG tags when dedicated Twitter Card meta tags aren't present. So if you've set og:title and og:image but haven't added twitter:card, X will still display a preview, though you get more control with dedicated Twitter Card markup. The summary_large_image card type gives you the biggest visual impact on X timelines.

LinkedIn follows standard OG implementation closely but caches data for about 7 days. Use LinkedIn's Post Inspector tool to force a refresh. Images work best at the 1.91:1 aspect ratio, just like Facebook.

WhatsApp and Telegram both generate link previews from OG tags in real time. If og:image loads slowly (over 2-3 seconds), the preview might appear without an image entirely. Keep your OG images lightweight. For best results, check your page load speed and make sure the image file loads quickly on its own.

Pinterest reads og:image but favors vertical images with a 2:3 aspect ratio. If you're targeting Pinterest traffic specifically, consider adding a taller image and using og:image alongside Pinterest-specific rich pin markup.

Quick Answers About the Open Graph Checker

What is an open graph checker?

An open graph checker is a tool that scans a webpage's HTML code and extracts the OG meta tags that control how the page appears when shared on social media. It validates whether required tags like og:title, og:image, og:url, and og:type are present and correctly formatted.

Is ToolsPivot's Open Graph Checker free?

Yes, 100% free with no usage limits. You can check unlimited URLs without creating an account, entering an email address, or paying anything. All features are available to every user on every scan.

What are the four required Open Graph tags?

The Open Graph Protocol requires og:title, og:type, og:image, and og:url on every page. These four tags give social platforms the minimum data needed to render a proper link preview card. Missing any one of them can result in a blank or broken social share.

What size should my og:image be?

The recommended size is 1200x630 pixels with a 1.91:1 aspect ratio. Facebook requires a minimum of 600x315 pixels to display a large link preview card. Images below 200x200 pixels may not display at all. Keep file size under 1MB for fast loading across platforms.

How is this different from the Facebook Sharing Debugger?

Facebook's debugger only shows how your link will render on Facebook. ToolsPivot's checker validates OG tags against the full protocol spec, previews how the link appears across multiple platforms, flags character length issues, and generates code for missing tags. It's a broader diagnostic tool, not just a Facebook preview.

Can I check OG tags on a competitor's website?

Yes. Paste any public URL into the checker. You'll see the exact OG tags your competitors are using, including their chosen images, titles, and descriptions. This is useful for benchmarking your social sharing strategy against others in your niche. You can also run their URL through the source code viewer for a broader view.

Do I need OG tags if I already have meta title and description?

Standard meta tags and OG tags serve different purposes. Meta title and meta description control how your page appears in Google search results. OG tags control how it appears on social media. Without OG tags, platforms will guess, and the result is often a mismatched image or a truncated headline.

Why does my link show the wrong image on Facebook?

Facebook caches OG data the first time a URL is shared. If you've changed your og:image since then, the old image persists until you clear the cache. Use the Facebook Sharing Debugger to scrape the URL again. Also confirm your og:image URL uses HTTPS and points to a valid, accessible image file.

How do I add OG tags to WordPress?

Install an SEO plugin like Yoast SEO, Rank Math, or All in One SEO. Each plugin adds OG tag fields to every post and page editor. Fill in the social title, description, and image, and the plugin inserts the proper meta tags into your HTML automatically. Run ToolsPivot's checker afterward to confirm everything rendered correctly.

Does the checker validate Twitter Card tags too?

It detects whether Twitter Card meta tags exist alongside your OG tags and flags their absence. For detailed Twitter Card validation and preview, use ToolsPivot's dedicated Twitter graph checker. Both tools complement each other for a complete social sharing audit.

Can OG tags help with SEO?

OG tags don't directly affect Google rankings. But they do affect how often your content gets clicked, shared, and linked to from social media. Higher engagement on social platforms drives referral traffic, brand mentions, and backlinks, which indirectly support SEO. Pair OG optimization with proper schema markup for the strongest combined effect.

What happens if I don't set any OG tags?

Social platforms will try to pull a title, description, and image from your page automatically. The result is unpredictable. Facebook might grab an irrelevant sidebar image. LinkedIn might truncate your title mid-sentence. Messaging apps might show a blank card. Setting explicit OG tags puts you in control of what people see.
