Open graph tags are meta information in the source code of a website, which provide information about the content of the website.

With the help of these OG tags, the title of the article, the desired thumbnail, information about the author, a short summary of the content and other information can be specified.

A complete list of all open graph tags and information on how to use them can be found here:

If this is a website that your team controls, your team can correct the open graph tags in the article's source code based on the error message. The Facebook Sharing Debugger helps you identify the error:

Note: due to API limitation, preview images are always displayed in 1200x600 pixels format.

If you have any further questions, don't hesitate to contact our support team either via chat or via support@swat.io!
