Is there a way to cascade the og metatags to all pages rather than having to enter them in each page?
Put them in the CODE section in the SETTINGS tab in the left menu, under RESSOURCES.
Just a heads up. Not a good idea for SEO. They should all be unique to each page in relation to the content on the page.
Thanks for the feedback. I do have a different description and title for each page, my primary concern was that the image does not have to be different for many of the pages.
