What is an Open Graph tag checker?

The Open Graph Checker reads and validates all Open Graph (OG) meta tags on any webpage. Open Graph tags control how your content appears when shared on Facebook, LinkedIn, Slack, and other platforms that support the OG protocol — including the title, description, image, and content type shown in social link previews.

When users share your content on social media, platforms read OG tags to generate a rich preview card. Without proper OG tags, platforms may display an incorrect title, wrong image, or no image at all — resulting in lower click rates from social shares. Properly configured OG tags directly impact your social media traffic.

Why use an Open Graph tag checker?

Social media is a significant traffic driver for most websites. A compelling, correctly configured Open Graph card dramatically increases click-through rates from social shares. This tool helps you ensure every page is optimised for maximum social media visibility.

What are Open Graph tags?

Open Graph tags are meta tags in your page's HTML head section that control how your content appears when shared on social media platforms. They were created by Facebook and are now used by most major platforms.

Which OG tags are required?

The four required OG tags are og:title, og:type, og:image, and og:url. Without these, platforms will attempt to scrape content automatically, often with poor results.

What size should og:image be?

The recommended og:image size is 1200×630 pixels with a 1.91:1 aspect ratio. This displays correctly on Facebook, LinkedIn, and Twitter. Images smaller than 600×315 won't generate large preview cards.

Do OG tags affect Google search rankings?

Open Graph tags don't directly influence Google search rankings. However, they improve social media click-through rates, driving more traffic and potential links — which can indirectly support SEO.

What if my og:image doesn't show on Facebook?

Use Facebook's Sharing Debugger to clear cached OG data for your URL after updating tags. Facebook caches OG data aggressively, so changes may not appear immediately without refreshing the cache.

Each one opens on its own page and works straight away, with no sign-up.
