Free Open Graph Checker
Use this Open Graph tester to check required OG properties, detected Open Graph tags, and preview-image data for one public page.
Validate Open Graph Tags for Better Social Preview & Sharing
Wranker analyzes your webpage's Open Graph tags, validates required OG properties, detects missing metadata, and previews how your content may appear when shared across Facebook, LinkedIn, X (Twitter), WhatsApp, and other platforms.
Validate Required Open Graph Tags
Check og:title, og:type, og:image and og:url, and distinguish missing properties from tags that are present but empty.
Review All Detected OG Properties
The OG tag checker output lists every extracted og:* value, including optional properties such as og:description and og:site_name.
Build an Open Graph Preview
Use the detected title, description, URL and og:image to create a focused simulation of the page's share-card metadata.
Review Open Graph Validation Issues
Use the Open Graph validator output to prioritise missing required properties, empty values, unavailable images, and fetch limitations.
Check Your Open Graph Tags Before Broken Social Previews Cost Clicks
Open Graph tags define the title, object type, representative image, and permanent URL used to describe a page as a social object. Wranker's Open Graph Checker helps teams review those source signals before publication, although each platform may still apply its own layout, crop, or cache.
Keep Shared-Page Identity Clear
Review og:title, og:type and og:url together so the intended page, object type, and destination are clear before the link is shared.
Catch Preview Image Problems Early
Confirm that og:image is present and that the referenced image can be fetched before editorial approval, campaign scheduling, or developer handoff.
Give Teams Clear Validation Evidence
Use the Open Graph validator output to show which required properties are missing, empty, or unavailable instead of reporting only that the preview is broken.
How to Use the Open Graph Tester in Four Steps
Use Wranker's Open Graph Checker to fetch one public page, extract its detected OG properties, check required fields and preview-image data, then review the Open Graph preview and validation findings before publishing.
Enter a Public Page URL
Submit the HTTP or HTTPS page you want the OG tag checker to analyse. Wranker fetches its HTML and records the final URL and response context.
Choose Stored or Fresh Scan
Use Wranker's stored result when appropriate, or request a fresh Open Graph check after the page's metadata has changed.
Extract and Validate Open Graph Tags
Wranker lists the detected og:* values, checks og:title, og:type, og:image, and og:url, and reviews the referenced image when possible.
Review Preview, Properties & Issues
Compare the simulated Open Graph preview with the extracted properties, then inspect required-property gaps and warnings before updating the page.
When to Use an Open Graph Checker
Use Wranker's Open Graph tester before publishing a page, when a shared link displays the wrong content, after CMS or template changes, or following redirects and migrations. Each Open Graph check provides page-level evidence for required properties, detected tags, and the preview image.
Validate Open Graph Tags Before Sharing
Run the Open Graph tags checker on a new article, landing page, product page, or campaign URL, then review the required properties and simulated Open Graph preview before promotion.
Diagnose Missing or Incorrect Share Cards
Use the OG tag checker when a shared link shows the wrong title, description, image, or destination, then inspect missing, empty, or unavailable source values.
Recheck Representative Pages After Deployment
Run the Open Graph validator on representative article, product, category, or landing-page templates after CMS, theme or plugin changes to confirm that required properties remain in the fetched HTML.
Validate Metadata After URL Changes
Repeat the Open Graph check after redirects, domain moves, or URL changes to confirm that the final page still returns the intended og:url, title, and image reference.
Continue Your Open Graph Validation Workflow
After using the Open Graph Checker, move to multi-platform social previews, canonical verification, redirect tracing, or a broader page-level SEO review.
MULTI-PLATFORM PREVIEW
Meta Tags & Social Preview Tool
Extend the Open Graph preview into Twitter Card checks, preview-image review, URL alignment, and Facebook-, LinkedIn-, and X-style simulations.
OpenCANONICAL IDENTITY
Canonical Tag Checker
Compare the declared canonical with the resolved final URL and verify the target status when og:url or page identity needs deeper review.
OpenREDIRECT PATH
URL Redirect Path Checker
Trace response codes, redirect hops, and the final destination when the Open Graph test resolves to an unexpected URL.
OpenBROADER PAGE SEO
Website SEO Analyzer
Review metadata, headings, content, links, images, indexability, and schema when the page needs more than a focused OG tag check.
Open Graph Checker FAQs
Get clear answers about Open Graph tags, required properties, preview images, validation results, fresh scans, repeated values, and how closely an Open Graph preview can match social platforms.
An Open Graph Checker fetches a public page and inspects the og:* metadata found in its HTML. Wranker reports detected properties, required fields that are present or missing, preview-image status, and a simulated card. You may also see the same tool category written as OpenGraph checker, Open Graph tester, or OG checker.
Open Graph tags are <meta> elements placed in a page's <head> to describe that page as an object in a social graph. They can specify the title, content type, representative image, and permanent URL, allowing compatible services to understand how the page should be represented when shared.
The four protocol-level required properties are: <meta property="og:title" content="Page title"> <meta property="og:type" content="website"> <meta property="og:image" content="https://example.com/image.jpg"> <meta property="og:url" content="https://example.com/page"> An Open Graph tags checker should count these separately from optional properties such as og:description, og:site_name and og:locale.
An Open Graph tester fetches the submitted page HTML, extracts detected og:* properties, checks the required property set and reviews the referenced preview image where possible. Wranker then organises the evidence into preview, tag, required-property and issue views. You can request a fresh Open Graph check when the page metadata has changed.
The terms overlap, but they can describe different levels of analysis. An OG tag checker may simply extract and display properties, while an Open Graph validator evaluates whether required fields are missing, empty, or malformed. An Open Graph tag checker or OG tags checker can combine both functions when it presents the original values and explains each finding.
The property may be absent, empty, inaccessible, redirected, protected from external requests, or returned with an unsupported response. The Open Graph protocol requires og:image and also supports structured properties for secure URL, MIME type, width, height, and alternative text. A platform cache can also continue showing an older image after the source page changes.
Open Graph supports repeated properties as arrays. When multiple og:image elements are present, the first one listed receives preference when values conflict. A checker should preserve every detected image and associate structured properties such as width, height, type, and alt text with the correct root image rather than silently discarding additional values.
No. Wranker's fresh-scan option bypasses Wranker's stored tool result and fetches the page again; it does not refresh external platform caches. Use Meta's Sharing Debugger for Facebook-specific scraping issues and LinkedIn Post Inspector when LinkedIn continues to show cached information. LinkedIn notes that refreshed data affects new posts, not existing ones.
No. An Open Graph preview is a simulation created from the metadata the checker can read. Facebook, LinkedIn and other platforms may apply their own fallback selection, image cropping, layout and caching rules. For broader Twitter Card checks and Facebook-, LinkedIn- and X-style comparisons, use Wranker's Meta Tags & Social Preview Tool.
Open Graph tags are primarily designed for social graph representation, not as direct Google ranking controls. Google documents its supported crawling, indexing, and snippet-related meta tags separately. An og:image may help indicate a representative image in some Google experiences such as Discover, but OG metadata does not replace the HTML title, meta description, canonical tags, or structured data.
