Enter a webpage URL to instantly preview how it looks when shared on Facebook, Twitter, and LinkedIn, and check OG tag completeness.
The OG Tag Preview Tool helps developers and SEO practitioners quickly check a webpage's Open Graph and Twitter Card tags, and preview how it looks when shared on social media platforms. Properly setting OG tags can significantly improve share click-through rates and brand image.
The Open Graph protocol was proposed by Facebook in 2010 and has become the de facto standard for social media sharing. Twitter Card is Twitter's extension protocol, and LinkedIn also supports OG tags. Key OG tags include: og:title (title), og:description (description), og:image (share image, recommended 1200×630px), og:url (canonical URL), og:type (content type). Twitter Card types include summary and summary_large_image.
Enter the webpage URL in the input field, and the tool will automatically fetch the page's Open Graph and Twitter Card tags, then simulate the share card preview on Facebook, Twitter, LinkedIn and other platforms.
Open Graph (OG) is a metadata protocol proposed by Facebook. It uses tags like og:title, og:description, and og:image to control the title, description, and image displayed when a webpage is shared on social media. Properly setting OG tags can significantly improve share click-through rates.
If OG tags are missing, social media platforms will automatically extract the title and description from the page, which may display incorrect or incomplete information. Images may not display or may show irrelevant images, seriously affecting share effectiveness and click-through rates.
Twitter Card is Twitter's proprietary metadata tags (twitter:card, twitter:title, etc.), while Open Graph is a universal protocol. Twitter prioritizes Twitter Card tags, falling back to OG tags if not present. It is recommended to set both for best compatibility.
