β FAQ
How to preview how a webpage looks when shared on social media?
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.
What are Open Graph tags?
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.
What happens if OG tags are missing?
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.
What is the difference between Twitter Card and Open Graph?
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.
