One of our customers discourse instance is configured that people have to register before they can access the content. One unwanted side-effect is when people share the URL of the website on social media the preview image shown on Facebook and Twitter is not their default opengraph image or twitter summary large image. On the login page the og:image and twitter:image html tags are not used in the HTML.
Currently there is no Opengraph meta data on the login page. Is this intentional? How would we be able to work around that?
It would probably be as simple as adding this (which is what we do in show.html.erb)
<% if @title %>
<% content_for :title do %><%= @title %><% end %>
<% content_for :head do %>
<%= raw crawlable_meta_data(title: @title, description: SiteSetting.site_description) %>
<% end %>
<% else %>
<% content_for :head do %>
<%= raw crawlable_meta_data(title: SiteSetting.title, description: SiteSetting.site_description) %>
<% end %>
<% end %>
I think all the data that gets used for OG Meta tags is already present on the login page… so I don’t think it’s omitted for privacy reasons or anything? Seems like we should add it.
