Cobra Open Graph Checker

Check your Open Graph and Twitter Card meta tags before sharing your page on social media. This free checker parses your HTML source, shows which tags are present or missing, gives actionable recommendations, and renders a preview of how your page will look on Facebook, LinkedIn, and Twitter. No signup, no server processing — everything runs in your browser using the native DOMParser API.

What are Open Graph tags?

Open Graph tags are HTML meta tags that control how your page appears when shared on social media platforms like Facebook, LinkedIn, and Pinterest. They define the title, description, image, and URL shown in the social share card.

Why should I check my Open Graph tags?

Pages without Open Graph tags display poorly when shared on social media — often with missing images, wrong titles, or generic descriptions. Checking your OG tags ensures your content looks professional and clickable when shared, which directly impacts traffic from social channels.

What is the difference between Open Graph and Twitter Card tags?

Open Graph tags (og:title, og:description, og:image) are used by Facebook, LinkedIn, and most platforms. Twitter Card tags (twitter:card, twitter:title, twitter:image) are Twitter-specific. Twitter falls back to OG tags if Twitter Card tags are missing, but having both gives you full control over each platform.

Can this tool fetch a live URL?

Due to browser security (CORS), fetching live URLs from a client-side tool is unreliable. The most reliable method is to paste your page's HTML source code directly. You can get this by right-clicking your page, selecting View Page Source, and copying the HTML.
