Open Graph Checker
Want to see how your webpage looks when shared on Facebook, LinkedIn, or Twitter? The free Open Graph Checker by Amaze SEO Tools scans any URL and extracts its Open Graph meta tags — showing you the exact title, description, image, and other metadata that social media platforms read when someone shares your link.
Amaze SEO Tools provides a free Open Graph Checker that fetches and displays the Open Graph (OG) meta tags from any webpage, letting you verify how your content will appear across social media platforms before anyone shares it.
Open Graph is a protocol originally created by Facebook that allows web pages to control how they appear when shared on social networks. When someone shares a link on Facebook, LinkedIn, Twitter, Pinterest, Slack, WhatsApp, or Discord, those platforms read the Open Graph meta tags embedded in the page's HTML to determine which title, description, image, and URL to display in the share preview card. Without properly configured OG tags, platforms either guess at what to show — often pulling the wrong image, a truncated title, or an irrelevant description — or display a plain, unappealing link with no preview at all.
Our checker reads the OG tags on any page and presents them clearly, so you can verify that the correct information is in place, spot missing tags, and fix issues before your audience shares the link and sees a broken or unattractive preview.
Input Field about Open Graph Checker Tool
Enter a Website URL
A single-line input field is labelled "Enter a website URL" with the placeholder "https://...". Paste or type the complete URL of the webpage you want to check — for example, https://www.yoursite.com/blog/latest-post. The tool fetches the page and extracts all Open Graph meta tags found in its HTML source. A clipboard icon on the right side of the field provides quick paste or clear functionality.
reCAPTCHA (I'm not a robot)
Below the input field, tick the "I'm not a robot" checkbox to pass the security verification before checking.
Action Buttons for Check Open Graph
Three buttons appear beneath the reCAPTCHA:
Check (Blue Button)
The primary action. After entering a URL and completing the reCAPTCHA, click "Check" to fetch the page and extract its Open Graph tags. The results display each detected OG property and its value on screen.
Sample (Green Button)
Loads an example URL into the input field so you can see what the checker output looks like before entering your own page address.
Reset (Red Button)
Clears the input field and any displayed results, returning the tool to its blank default state for a new check.

- Fix any missing or incorrect tags in your page's HTML, then re-check to confirm the updates are in place.
Open Graph Tags Explained
The Open Graph protocol defines a set of meta tags placed in the <head> section of a webpage's HTML. Each tag uses the property attribute prefixed with og: and a content attribute containing the value. Here are the core OG tags the checker looks for:
og:title
The title of your page as it should appear in social share previews. This is the large, clickable headline displayed in the share card. It should be concise, compelling, and accurately describe the page content. If missing, platforms fall back to the page's <title> tag, which may not be optimised for social sharing context.
<meta property="og:title" content="Your Page Title Here" />
og:description
A brief summary of the page content displayed beneath the title in share previews. This should be one to two sentences that entice the reader to click through. If absent, platforms may pull text from the meta description or page body, often with unpredictable results.
<meta property="og:description" content="A concise summary of your page." />
og:image
The URL of the image displayed in the share preview card. This is the single most impactful OG tag — posts with compelling images receive dramatically higher engagement than those with generic or missing images. The recommended minimum size is 1200 × 630 pixels for optimal display across platforms. If no og:image is specified, platforms may select a random image from the page or display no image at all.
<meta property="og:image" content="https://yoursite.com/images/share-image.jpg" />
og:url
The canonical URL that the share should point to. This ensures that social engagement metrics (likes, shares, comments) consolidate under a single URL rather than splitting across URL variations with different query parameters or trailing slashes.
<meta property="og:url" content="https://yoursite.com/page" />
og:type
Describes the type of content the page represents. Common values include website (for general pages), article (for blog posts and news), product (for e-commerce items), and video.other (for video content). The type helps platforms understand context and may influence how the preview is formatted.
<meta property="og:type" content="article" />
og:site_name
The name of the overall website or brand. Displayed alongside the page title in some platform layouts, it provides brand context — for example, "The New York Times" or "Your Company Blog." This helps readers identify the source at a glance.
<meta property="og:site_name" content="Your Brand Name" />
og:locale
The language and regional format of the content, expressed as a locale code such as en_US (American English), en_GB (British English), or fr_FR (French). This helps platforms serve the share preview in the appropriate language context.
<meta property="og:locale" content="en_US" />
Additional Tags
The checker may also detect optional properties including og:image:width, og:image:height, og:image:alt, og:video, og:audio, and og:image:type. These provide additional metadata that helps platforms display your content optimally.
Real-World Use Cases
1. Pre-Launch Social Sharing Verification
Before promoting a new blog post, product page, or landing page on social media, run the URL through the checker to confirm the share preview looks exactly as intended. Catching a missing image or a truncated title before anyone shares the link prevents a poor first impression with your audience.
2. Debugging Incorrect Share Previews
If a page is displaying the wrong image, an outdated title, or a missing description when shared on Facebook or LinkedIn, the checker reveals exactly what OG tags the page currently contains — pinpointing which tag is wrong, absent, or serving stale cached content.
3. Auditing Competitor Social Media Presence
Analysing how competitors configure their OG tags reveals their social sharing strategy — what images they prioritise, how they craft share-optimised titles and descriptions, and which OG properties they implement. This insight informs your own social optimisation approach.
4. Quality Assurance for Web Development Projects
Developers and QA teams include OG tag verification as part of their pre-deployment checklist. The checker provides a quick pass/fail review of all social meta tags without needing to view the page source or share the link on actual social platforms during testing.
5. Content Management and Template Validation
Website managers running a CMS (WordPress, Shopify, Wix, Squarespace) use the checker to verify that their theme or SEO plugin is generating correct OG tags dynamically for each page. A template misconfiguration can cause hundreds of pages to share with incorrect metadata — catching this early saves significant remediation effort.
6. Verifying OG Tags After CMS or Plugin Updates
CMS updates, theme changes, and SEO plugin upgrades can inadvertently alter or remove OG tag output. After any significant site update, spot-checking key pages with the checker confirms that social sharing metadata remains intact and correct.
7. Optimising E-Commerce Product Sharing
Online stores benefit from product-specific OG tags that display the product image, name, and price summary when shoppers share items with friends. The checker verifies that each product page generates its own unique OG metadata rather than falling back to a generic site-wide default.
Open Graph and Social Platforms
While Open Graph was created by Facebook, its adoption extends across virtually all social and messaging platforms:
- Facebook — The native consumer of OG tags. Uses og:title, og:description, og:image, og:url, and og:type to construct share previews in the news feed, Messenger, and group posts.
- LinkedIn — Reads OG tags to generate link preview cards in feed posts, articles, and direct messages. The og:image is especially critical for professional engagement.
- Twitter/X — Supports both Twitter Card meta tags (
twitter:title,twitter:image) and falls back to OG tags when Twitter-specific tags are absent. Implementing OG tags covers both platforms. - Pinterest — Uses og:image for pin previews and og:description for pin descriptions when users save pages to boards.
- Slack and Discord — Display rich link previews in message threads using OG tag data, including the title, description, and image.
- WhatsApp and Telegram — Show link preview cards in chat messages pulled from OG tags, making the share look professional rather than displaying a raw URL.
Common OG Tag Issues and How to Fix Them
- Missing og:image. The most impactful problem. Social shares without images receive significantly lower engagement. Add an og:image tag pointing to a high-quality image of at least 1200 × 630 pixels. Use absolute URLs (starting with
https://), not relative paths. - Image too small or wrong aspect ratio. Facebook recommends 1200 × 630 pixels (1.91:1 ratio). Images smaller than 600 × 315 pixels may display as small thumbnails instead of large preview cards, dramatically reducing visual impact.
- Generic or duplicate titles across pages. Every page should have a unique og:title reflecting its specific content. If every page on your site shares the same OG title (often the site name), your social previews will look identical and uninformative regardless of which page is shared.
- Missing og:description. Without a description, platforms guess at what text to show — often pulling the first paragraph, navigation text, or cookie banner content. Write a deliberate, compelling summary for each page.
- Stale cached previews on Facebook. Facebook caches OG data aggressively. After updating your tags, use Facebook's Sharing Debugger tool to force a cache refresh. The checker shows what is currently on your page, but Facebook may serve an older cached version until manually cleared.
- Using relative image URLs. OG image tags must contain absolute URLs (
https://yoursite.com/image.jpg), not relative paths (/image.jpg). Relative URLs cause the image to fail to load in share previews on external platforms.
Open Graph Checker vs Meta Tags Analyzer
Both tools inspect page-level metadata, but they focus on different tag sets:
- Open Graph Checker (this tool) — Specifically extracts and displays OG meta tags that control social media share previews (og:title, og:image, og:description, etc.).
- Meta Tags Analyzer — Examines broader HTML meta tags including the page title, meta description, meta keywords, viewport, robots directives, and other head-level metadata that affects search engines and browser behaviour.
Use both tools together for a complete picture: the Meta Tags Analyzer for search engine optimisation, and the Open Graph Checker for social media optimisation.
Frequently Asked Questions
Q: What are Open Graph tags?
A: Open Graph tags are HTML meta tags placed in a page's <head> section that control how the page appears when shared on social media platforms. They define the title, description, image, URL, and content type that platforms display in share preview cards.
Q: Which platforms use Open Graph tags?
A: Facebook, LinkedIn, Pinterest, Slack, Discord, WhatsApp, Telegram, and many other platforms read OG tags to generate link previews. Twitter/X supports OG tags as a fallback when its own Twitter Card tags are not present.
Q: What is the recommended image size for og:image?
A: Facebook recommends a minimum of 1200 × 630 pixels with a 1.91:1 aspect ratio. Images at this size or larger display as full-width preview cards across most platforms. Smaller images may appear as reduced thumbnails with significantly less visual impact.
Q: Why does my Facebook share still show the old image after I updated the tag?
A: Facebook caches Open Graph data. After updating your OG tags, use Facebook's Sharing Debugger tool (developers.facebook.com/tools/debug/) to scrape the page again and force Facebook to refresh its cached preview. The Open Graph Checker shows your current live tags, but Facebook may serve its cached version until manually cleared.
Q: Do Open Graph tags affect SEO rankings?
A: OG tags do not directly influence search engine rankings. However, better social share previews lead to higher engagement, more shares, and increased referral traffic — which can indirectly benefit your SEO through greater visibility and more backlinks.
Q: What happens if my page has no OG tags?
A: Platforms will attempt to construct a preview by guessing — typically pulling the page's <title> tag for the headline, the meta description or first paragraph for the summary, and a random image from the page. The result is usually unpredictable and often unappealing.
Q: Can I check pages on sites I do not own?
A: Yes. The checker reads publicly accessible OG tags from any URL. This is useful for auditing competitor pages, verifying how third-party content will preview when you share it, and researching OG implementation best practices across different websites.
Q: Is the URL I enter stored or shared?
A: No. The URL you enter and the OG tag data retrieved are not saved, logged, or transmitted to any third-party service. The check runs entirely within the tool interface.
