https://ogp.me/ states that " The four required properties for every page are:
og:title- The title of your object as it should appear within the graph, e.g., “The Rock”.
og:type- The type of your object, e.g., “video.movie”. Depending on the type you specify, other properties may also be required.
og:image- An image URL which should represent your object within the graph.
og:url- The canonical URL of your object that will be used as its permanent ID in the graph, e.g., "https://www.imdb.com/title/tt0117500/"."
But is it me, or is webflow missing the canonical url tag? I guess this could be entered manually, but that is a faff
I assume there is some code to automate this on webflow?
