What Are Open Graph Meta Tags?

Open Graph (OG) meta tags are snippets of HTML code that control how your web pages appear when shared on social media platforms. Created by Facebook in 2010, the Open Graph protocol has become the universal standard for social media previews. When someone shares your URL on Facebook, Twitter/X, LinkedIn, Discord, Slack, or WhatsApp, these platforms read your OG tags to generate a rich preview card with a title, description, and image.

Without Open Graph tags, social media platforms attempt to guess what to display, often pulling the wrong image, a truncated title, or no description at all. This results in unappealing link previews that get fewer clicks and shares. An Open Graph checker like this tool lets you verify your tags are correct before sharing, ensuring every link you post looks professional and drives maximum engagement.

Example Open Graph tags:

<meta property="og:title" content="Your Page Title" />
<meta property="og:description" content="A brief page summary" />
<meta property="og:image" content="https://example.com/image.jpg" />
<meta property="og:url" content="https://example.com/page" />

All Open Graph Tags Explained

og:titleRecommended

The title of your page as it should appear in social media previews. Keep it concise and compelling, this is the headline people see when your link is shared.

Pro tip

Keep under 60 characters to avoid truncation on most platforms.

og:description

A brief summary of your page content. This appears below the title in social media cards and should entice users to click.

Pro tip

Aim for 55-200 characters. Front-load important keywords.

og:imageRecommended

The preview image URL shown in social media cards. This is the most visually impactful tag, a good image dramatically increases click-through rates.

Pro tip

Use 1200x630px (1.91:1 ratio). Always use an absolute URL starting with https://.

og:urlRecommended

The canonical URL of your page. This tells social platforms which URL to use as the permanent link, even if the page is accessed via a different URL.

Pro tip

Use the same URL as your <link rel="canonical"> tag.

og:typeRecommended

The type of content on the page. Common values are "website" for homepages and "article" for blog posts. This helps platforms categorize your content.

Pro tip

Use "website" for landing pages, "article" for blog posts, "product" for e-commerce.

og:site_name

The name of your website or brand. This appears above the title in some social previews (like Facebook) and helps users identify the source.

Pro tip

Use your brand name, not your domain.

og:locale

The language and region of your content in the format language_TERRITORY (e.g., en_US). Helps platforms serve the right language version.

Pro tip

Default is en_US if not specified. Use for multilingual sites.

og:image:width

The width of the og:image in pixels. Specifying dimensions helps platforms render your image faster without needing to download it first.

Pro tip

Set to 1200 for the recommended 1200x630 image size.

og:image:height

The height of the og:image in pixels. Combined with og:image:width, this prevents layout shift when the preview card loads.

Pro tip

Set to 630 for the recommended 1200x630 image size.

Twitter Card Tags Explained

Twitter Card tags control how your links appear specifically on Twitter/X. When both OG tags and Twitter Card tags are present, Twitter uses the Twitter-specific tags. When only OG tags exist, Twitter falls back to those.

twitter:card

Controls the card type: "summary" (small square image) or "summary_large_image" (large landscape image). This is the most important Twitter-specific tag.

Pro tip

Use "summary_large_image" for most pages, the larger image gets significantly more engagement.

twitter:title

The title shown in the Twitter/X card. Overrides og:title when present. Twitter truncates titles longer than about 70 characters.

Pro tip

If your og:title works well, you can skip this tag, Twitter will use og:title as fallback.

twitter:description

The description shown in the Twitter/X card. Overrides og:description when present.

Pro tip

Keep under 200 characters. Twitter may truncate longer descriptions.

twitter:image

The image shown in the Twitter/X card. Overrides og:image when present. Must be an absolute URL.

Pro tip

Minimum 144x144 for summary, 300x157 for summary_large_image. Max 5MB.

twitter:site

The @username of the website or brand that the content belongs to. Appears in the card footer.

Pro tip

Include the @ symbol. Example: @flyn_to

twitter:creator

The @username of the content author. Useful for articles and blog posts to credit the writer.

Pro tip

Use for blog posts and articles where the author has a Twitter/X account.

Common Open Graph Mistakes to Avoid

Missing og:image tag

Without an og:image, social platforms display a generic placeholder or try to extract a random image from your page. This dramatically reduces click-through rates. Always include a high-quality, relevant preview image.

Using relative image URLs

Open Graph image URLs must be absolute (starting with https://). Relative paths like "/images/preview.jpg" will not work. Social media crawlers cannot resolve relative URLs since they do not know your domain.

Image too small or wrong aspect ratio

Images smaller than 200x200 pixels may be ignored by Facebook. The recommended size is 1200x630 pixels (1.91:1 ratio). Using square images when summary_large_image is set results in awkward cropping.

Not setting twitter:card

Without a twitter:card meta tag, Twitter/X defaults to a basic link with no image preview. Set twitter:card to "summary_large_image" for the best visual impact in the Twitter/X feed.

Duplicate or conflicting tags

Having multiple og:title or og:description tags confuses crawlers, they may pick the wrong one. Ensure each OG tag appears exactly once in your HTML <head>. Check for duplicate tags from CMS plugins.

Forgetting to clear social media cache

Social platforms cache your OG data for hours or days. After updating tags, use Facebook Sharing Debugger, Twitter Card Validator, or LinkedIn Post Inspector to force a re-scrape and see your changes.

Custom OG Tags + Link Shortener: Why You Need Both

Checking your OG tags is the first step. With Flyn, you can override OG tags on any short link, even if the destination page has poor or missing tags.

Custom preview images

Set a custom og:image on your short link. Perfect for affiliate links, landing pages, or sites you do not control.

Custom titles & descriptions

Override og:title and og:description for each link. Tailor social previews for different audiences and campaigns.

Preview before sharing

Frequently Asked Questions

What are Open Graph tags?
Open Graph (OG) tags are meta tags placed in the <head> section of your HTML that control how your page appears when shared on social media platforms like Facebook, Twitter/X, LinkedIn, Discord, Slack, and WhatsApp. They define the title, description, image, and URL that appear in the social media preview card. Without OG tags, platforms guess what to display, often resulting in broken or unappealing previews.
What is the difference between Open Graph tags and Twitter Cards?
Open Graph tags (og:title, og:description, og:image) were created by Facebook and are used by most social platforms as the default standard. Twitter Cards (twitter:card, twitter:title, twitter:description, twitter:image) are Twitter/X-specific tags that override OG tags when present. If you only set OG tags, Twitter will fall back to them. For the best results, set both OG tags and Twitter Card tags so you have full control over how your content appears on every platform.
What is the ideal Open Graph image size?
The recommended Open Graph image size is 1200 x 630 pixels with a 1.91:1 aspect ratio. This works well across Facebook, LinkedIn, Discord, and most platforms. For Twitter/X summary_large_image cards, the same 1200x630 size works perfectly. For Twitter summary cards (small square), use 144x144 pixels minimum. Always keep your image under 5MB and use JPG or PNG format. Place important content in the center of the image, as some platforms crop edges.
Why is my Open Graph image not showing on Facebook?
Common reasons your OG image is not showing on Facebook: the image URL is incorrect or returns a 404, the image is too small (minimum 200x200 pixels), the image file is too large (over 8MB), Facebook has cached an old version of your page, or your server blocks Facebook's crawler. Use Facebook's Sharing Debugger tool to clear the cache and force a re-scrape. Also check that your og:image tag uses an absolute URL (starting with https://), not a relative path.
What Open Graph tags are required?
The four essential OG tags recommended by the Open Graph protocol are: og:title (the title of your page), og:type (the type of content, usually "website" or "article"), og:image (the preview image URL), and og:url (the canonical URL of your page). Additionally, og:description is strongly recommended for better social previews. For Twitter, include twitter:card to control the card type (summary or summary_large_image).
How do I add Open Graph tags to my website?
Add OG tags as <meta> elements in the <head> section of your HTML. For example: <meta property="og:title" content="Your Page Title" />, <meta property="og:description" content="Your description" />, <meta property="og:image" content="https://example.com/image.jpg" />, and <meta property="og:url" content="https://example.com/page" />. In Next.js, use the metadata export. In WordPress, use plugins like Yoast SEO or RankMath. In Shopify, themes usually handle OG tags automatically.
How do I debug Open Graph tags?
Use this Open Graph checker tool to instantly preview how your URL appears on 6 major platforms. For platform-specific debugging: use Facebook's Sharing Debugger (developers.facebook.com/tools/debug/) to clear Facebook's cache, Twitter Card Validator (cards-dev.twitter.com/validator) for Twitter/X, and LinkedIn Post Inspector (linkedin.com/post-inspector/) for LinkedIn. Our tool checks all tags at once and gives you a social share score with actionable recommendations.
Do Open Graph tags affect SEO?
Open Graph tags do not directly affect your search engine rankings. Google uses its own algorithms to generate search snippets and does not rely on OG tags. However, OG tags indirectly impact SEO by improving click-through rates from social media. A compelling title, description, and image in social previews drive more clicks, shares, and traffic, which can improve engagement signals. Think of OG tags as social media SEO, they optimize your content for social discovery.
How often should I check my Open Graph tags?
Check your OG tags whenever you publish new content, redesign your website, change your CMS or theme, or notice broken social previews. It is also good practice to audit OG tags quarterly across your most-shared pages. Common issues include missing images after site migrations, broken image URLs after CDN changes, or outdated descriptions that no longer match the page content.
What is a social share score?
The social share score in our Open Graph checker is a 0-100 rating that evaluates how well-optimized your page is for social media sharing. It checks for essential OG tags (og:title, og:description, og:image), Twitter Card tags, proper image dimensions, description length, canonical URL, favicon, and more. A score of 80+ means your page is well-optimized for social sharing. The tool also lists specific issues to fix and what you are doing right.
Is this Open Graph checker free?
Yes, this Open Graph checker is 100% free with no sign-up required. You can check unlimited URLs, preview social cards for 6 platforms (Twitter/X, Facebook, LinkedIn, Discord, Slack, WhatsApp), view all meta tags, and track your check history, all without creating an account.
