I am defining a custom og:type. For example “watchevent:event”.
In the html page containing this “event” object i have defined meta tag,
meta property=”og:type” content=”watchevent:event”
But once i debug this html page using Facebook object debugger it is showing the og:type property as “article”.
Why is the custom og:type not shown?
Perhaps you have a caching issue?
Try adding a “refresh” parameter in the debugger:
