You can’t edit ghost_head because it’s a helper. If you want to override the metadata, you’ll need to create a template that doesn’t use the helper, but does include the same content
Obviously I can view the HTML output but not the helper file. I want to make some small changes to the social graph output and don’t want to break anything else.
I was looking for more information such as the following, https://github.com/TryGhost/Ghost/issues/3900 this gives a lot of the intention of ghost_head structured data and open graph, but some information is missing
