Facebook Share/Specifying Meta Tags - Facebook Developer Wiki

by 1 other
Facebook Share passes along the URL of your page to our servers, which in turn looks up certain HTML tags within it. Those tags are used to display a preview of the page. In order to provide this preview, we always look for the title of the page, a summary of the main content and an image. If there's media content on the page, those media files are also important to identify.
