What is Open Graph Checker?

The Open Graph Checker is a free tool that analyzes any web page's Open Graph meta tags and shows you a live preview of how your link will look when shared on social media platforms like Facebook, LinkedIn, WhatsApp, Slack and Discord. Open Graph (OG) tags are HTML meta tags that control the title, description, image and other properties displayed in social share cards. Without proper OG tags, shared links appear as plain text with no image, which dramatically reduces click-through rates. This tool fetches the page server-side and extracts all og:* properties so you can verify everything looks right before sharing.

Frequently asked questions

What are Open Graph tags?

Open Graph tags are HTML meta tags (like <meta property="og:title" content="...">) that tell social media platforms what title, description, image and other info to show when someone shares your link. They were created by Facebook in 2010 and are now used by LinkedIn, WhatsApp, Slack, Discord, Telegram and more.

Which Open Graph tags are required?

The six most important OG tags are og:title, og:description, og:image, og:url, og:type and og:site_name. At minimum you need og:title and og:image for a good social share appearance. Missing og:image is the single biggest cause of poor-looking shared links.

What image size should I use for og:image?

Facebook recommends 1200x630 pixels for optimal display. LinkedIn uses the same dimensions. The image should be at least 200x200 pixels to be accepted. Keep the file size under 8MB and use JPEG or PNG format.

Why does my preview look different on Facebook vs LinkedIn?

Each platform caches OG data independently. After updating your OG tags, you need to clear the cache on each platform. Use Facebook Sharing Debugger and LinkedIn Post Inspector to force a re-scrape of your page.

Do OG tags affect SEO rankings?

OG tags do not directly affect search engine rankings. However, they significantly impact social media click-through rates, which drives traffic. Better-looking shared links get more clicks, more shares, and indirectly more backlinks — all of which help SEO.

What is og:type and what should I set it to?

og:type tells platforms what kind of content the page is. Use "website" for your homepage, "article" for blog posts, "product" for product pages. If omitted, platforms default to "website" but it is best practice to set it explicitly.

Can I check pages that require login?

No, this tool can only check publicly accessible pages. If your page requires authentication, the tool will see the login page instead of your actual content.
